The More info sheet now lists every ranking a station qualifies for, directly under the map and above the price and distance: the same StationLabelBadge the listing rows render, in a flow layout so two or three capsules wrap to a new line rather than truncating at large Dynamic Type.
The rules are not restated. StationRanking defers to StationRecommendationBadge.badge for the Best Value gate, and takes Cheapest and Top as the flags the host list already computed for its own rows, so the sheet cannot award a capsule the row behind it withheld. A host passes one of the two, never both: Stations sends isCheapestInRange, Favourites sends isTopFavourite. No calculation, ranking, eligibility or savings logic changed.
Rename the card heading Best Value to Value breakdown, since the working behind it can end in Costs rather than a saving, and drop the green section tint so the card matches the neutral background used elsewhere in the sheet. The Saves, Break even and Costs capsules and every breakdown row are untouched.
Rename the explanation link to How does FuelBoard calculate value? It names the calculation rather than the feature, of which the Best Value gate is only the last step. The sheet's own title stays short: the full question truncated to 'How does FuelBoard...' as a navigation title at both inline and large display modes, so the row carries the question and the sheet names the topic.
Tests: 269 pass, 5 new covering capsule selection, order and sheet-vs-row agreement on Best Value.
One adaptive tone palette and one shape rule now drive every capsule on
Stations, Favourites, the detail sheet and the Key.
- CapsuleTone: the light/dark palette pairs in one place, resolved through a
UIColor dynamic provider so a List row that re-renders without rebuilding
its body still follows an appearance switch. Every pair clears 4.5:1
foreground-on-background in both appearances (4.96-6.72:1).
- AdaptiveCapsule: capsule at one drawn line, rounded rect at two or more,
radius 8 -> 10, measuring content before padding so insets cannot inflate
the line count.
- Listing verdict capsules move from white-on-muted-solid to the tinted
palette, so Saves, Break even, Costs and Closest station read the same in
the rows and in the detail sheet.
- Best Value is purple, not green: green stays reserved for a financial
saving, which is what the Saves capsule beside it means.
- Price dots standardise to 12pt in the app (widget keeps its own 6pt dot;
PriceRatingDot now takes a diameter so the difference is deliberate).
- Station labels are sentence case with their recommended symbols (medal, tag,
location.north.fill, trophy) and StationLabelKind replaces the Key's
string-literal dispatch, so renaming a label can no longer drop a row.
- Key says "Costs", matching the capsule's own headline (was "Costs more").
29 was used for two different binaries during the listing refinement, so
the next install would have been indistinguishable from the last one.
Raised in all eight configurations — app, widget, watch app and watch
extension, Debug and Release — so the whole bundle reports one number.
Favourites gains the same info button the Stations list has, last in
the trailing toolbar group so it sits to the right of Edit. It stays
visible when the list is empty, because the legend explains the prices
and labels before anything is starred — Trends and Edit still hide
with no favourites.
The legend itself is now one view, KeySheetView, lifted out of
StationsView's private computed property so both tabs present the
same sheet and cannot drift apart. It lives in StationsView.swift
because the key's row types are file-private there, which keeps the
Xcode project untouched. Stations passes its selected fuel's tint and
Favourites its active tab's, so the station-label pump badge matches
the rows on screen; everything else — detents, the two nested sheets,
and the -showKeySheet / -showBestValueInfo / -showImportantInfo QA
launch hooks — behaves exactly as before.
The capsule's shape was keyed to the verdict's declared line count, so
"Closest station" — one declared line — always drew as a Capsule while
its text wrapped to two lines in the row's narrow column, leaving the
semicircular ends crowding the words they wrapped. Saves never showed
this because its amount line makes the declared count two.
The shape now follows the DRAWN height: a GeometryReader behind the
text block reports what it actually rendered, divided by the caption's
line height taken through ScaledMetric so the test holds at every
Dynamic Type size. One drawn line keeps the capsule; two or more get
the same 8pt rounded rect the other verdicts use. The first layout
pass, before there is a height, falls back to the declared count.
The listing's verdict capsule now carries white text on muted semantic
fills instead of the neutral secondary tint: Saves #45825E, Costs
#A9635B, Break even #707070, Closest #58789D.
Fixed tones, not translucent tints, because white text on a 15% tint
over a white row measures ~1.8:1. Each tone sits at a relative
luminance of ~0.18 — the band where white clears 4.5:1 AND the pill
still separates ~3:1 from both a white row and the dark card fill — so
one value each works in light and dark without a dynamic colour. The
saturated palette colours cannot carry white text at all: systemGreen
measures 2.2:1, systemRed 3.6:1.
"Save" becomes "Saves", matching the detail sheet and reading as a
statement of the outcome; amounts, symbols, padding, radius and the
shape-follows-line-count rule are unchanged. Saves and Costs share an
84pt minimum width so their trailing edges line up down the list.
The price and its capsule are now one vertically grouped element (5pt),
with the badge keeping the column's full 12pt above, so the row no
longer reads as three equal lines.
Station names cap at three lines with a tail ellipsis: unbounded wrap
let one very long forecourt name set the height of the whole row. 59 of
the 8,073 names in the dump exceed three lines and now ellipsise; the
full name is always in Station Details. Addresses still wrap freely.
The baseline pill moves onto ListingFuelSavingsCapsule so the listing
shows the same soft blue and white text as its siblings, leaving
FuelSavingsCapsule to the detail sheet, which it now alone uses.
Badges keep their tinted styling: they annotate a price rather than
report an outcome.
Verified: 261/261 swift test; Debug simulator and Release device
builds; all four fills and their white text measured from simulator
pixels in both appearances, and the detail sheet's .blue absent from
the listing entirely.
Station and Favourite rows share one capsule, so both now read
"Save / £3.10" and "Costs / £1.20 more" instead of the amount-free
"Saves" / "Costs more". "(approx.)" is appended on its own line when the
journey behind the figure was estimated. Break even carries no figure —
±£0.05 is noise — so it stays a single line unless the qualifier adds one.
- Split `listingCapsuleHeadline()` into a structured `ListingVerdict`
(headline / amount / qualifier) drawn as one Text per line, so where the
capsule breaks is decided by the data rather than by the width the price
column happened to hand it: the figure can never straddle two lines.
- The capsule's shape follows its line count: one line stays a Capsule, two
or more switch to a rounded rect at 8pt, whose corners do not crowd a
taller block the way a pill's semicircular ends do.
- The Key sheet's legend renders the same component with `showsAmount:
false`, so it demonstrates the wording without displaying the placeholder
£1.00 figure it was built from.
- The new words ("Save", "Costs", "(approx.)", "%@ more") go into
Localizable.strings so the copy editor owns them; amounts run through
FuelSavingsFormat.money and the amount line is monospaced.
- VoiceOver keeps the single-line form, since a drawn break is a pause
mid-phrase when spoken.
Tests cover the line structure for all four statuses, the estimated
qualifier and the amount-free legend. Pixel measurement on the simulator
confirms the shape rule: one line measures a radius of h/2 (a pill), two
lines measure 8pt, in both light and dark.
- Alerts: drop the alert-type picker and the Best Value alert path, so
proximity alerts always follow the cheapest station. A stored `bestValue`
selection now falls back to cheapest when loaded.
- Key sheet: the price-rating, savings, station-label and favourite wording
comes from `KeySheetContent` in Shared/FuelSavings.swift — a Foundation-only
model with tests that pin the exact meaning of each indicator — and the
sheet is built from that model rather than inline strings.
- BACKLOG: record the plan to restore Best Value proximity alerts behind one
shared evaluator (user-location baseline, a single disclosed qualification
rule, and real/Test alert parity).
- Bump CURRENT_PROJECT_VERSION to 29.
One sheet, reachable from the bottom of the Key sheet and from the bottom
of Settings, with each topic as its own card and heading:
- Fuel Prices, Fuel Availability, Savings & Best Value, Journey Estimates,
Before You Travel and Disclaimer, in that order.
- Every heading carries an SF Symbol in a fixed-width, Dynamic-Type-aware
slot, so heading text lines up across sections regardless of glyph width.
Icons take the accent colour, headings are semibold and primary, and each
description sits beneath its heading in secondary text.
- All copy lives in en.lproj/Localizable.strings keyed by the English
literal, ready for the web copy editor.
- The sheet, its trigger row and the .importantInformationSheet(isPresented:)
modifier live in one file, so any further entry point is a one-line change
and the wording cannot drift between them.
- DEBUG-only `-showImportantInfo` launch hook, chained behind the Key sheet,
for screenshotting without a tap.
The Replay onboarding section rendered its description as a section footer, so
the text sat below the card while every other control card shows its description
inside the card above a hairline. Move the same copy into the section body as a
footnote/secondary row. Wording, the replay action and its behaviour are
unchanged; only the Fuel Savings general explanation and the Support tip note
remain section footers.
The Tap action section rendered its description as a section footer, so the
text sat below the card while Units, Distances and Data checking show their
descriptions inside the card, separated from the control above by a hairline.
Move the same copy into the section body as a footnote/secondary row so the
card matches its neighbours. Wording is unchanged and no behavioural or
persistence code is touched.
Rewrite the Settings screen in short British English and remove the
duplicated paragraphs, keeping every control, binding and preference key as
it was.
- Fuel Savings: one-line descriptions for Best Value, average fuel economy,
fill-up amount (worded for the unit in use) and minimum saving; one concise
general explanation replaces the long footer; the orange "New comparison
basis" notice is removed.
- Units: "Station sign" becomes "Pence per litre"; the combined paragraph
becomes two contextual descriptions.
- Distances: "Accurate distances" becomes "Driving distances" with a short
description; the route-request and search-radii paragraph is removed.
- Tap action: "Open map"/"More info" become "Directions"/"Station details"
with a short description.
- Data checking: Standard and Smart summaries cut to one line each, one shared
background-update note, duplicated footer removed.
- Replay onboarding: shorter description. Support FuelBoard untouched.
Copy and layout only: no calculations, ranking, refresh schedules, stored
values or persistence changed. New and reworded literals live in
FuelBoard/en.lproj/Localizable.strings.
Both sliders now move a local draft (mpgDraft / fillUpDraft) and write once,
when the drag ends, via Slider's onEditingChanged. While the thumb is down only
this screen redraws: no store write, no fuelSavingsSettings mutation, and so no
app-wide recompute — ContentView re-ran its body, rebuilt the savings lookup,
and passed all 8,130 stations through the alert monitor on every step.
The drafts are Double?, where nil means "not dragging" and the stored setting is
shown. That falls back naturally after a commit, so the control shows what was
actually saved (the clamps can lower it) and anything changing the setting from
outside — a unit switch, the in-list control, a QA hook — is reflected without
any re-seeding.
The MPG and fill-up read-outs follow the draft, so the figure still tracks the
thumb.
The keychain write deliberately stays on the main thread: it is the
authoritative mirror on read, so an async write could hand a relaunch or a
widget a stale value. One write per gesture is cheap enough not to need it.
The Settings sliders called persistFuelSavingsSettings() on every value change,
which rewrote all four keys — four UserDefaults writes and four keychain round
trips per step, on the main thread, up to 90 times per drag. That is what made
them stutter.
saveFuelSavingsField(_:from:) writes just the field that moved, so a slider
gesture touches one key.
writeKeychain now uses SecItemUpdate and only falls back to SecItemAdd on
errSecItemNotFound. Delete-then-add cost two round trips to securityd and
briefly left the key holding no value at all — a window where the keychain, the
authoritative mirror on read, could disagree with the app-group defaults.
Tests pin the store half: a single-field save leaves the other three keys alone,
and the whole-settings save still writes all four.
The explanation sheet now carries a full-width button that closes it and the
sheet it was opened from, then lands on Settings — whose Best Value section is
the first thing in its list, so the controls are on screen on arrival. It uses
.controlSize(.large), the standard iOS button height.
Both the More info sheet and the Key sheet are presented by StationsView, and
FavouritesView presents its own More info sheet — not ContentView's monitor as
assumed — so each host closes whichever sheet it owns on the notification.
Before this, one of them stayed up over the Settings tab. The button now
announces itself half a second after its own dismissal, so the child and parent
dismissals cannot race and drop one of the two.
The Best Value card states its verdict once. The badge is now the large capsule form the sheet used to repeat on its own line, so the same headline no longer appears twice, and the comparison caption ("vs closest station" / "your baseline") sits under the capsule — on the card and on the listing rows alike. The row's size-class split, which put the caption beside the capsule at regular width, is gone, so the pair reads the same on every device.
The facts row's price now follows Settings -> Units -> Price display. It called FuelStore.priceText(price, style: .stationSign) with the style hardcoded, so a Pounds & pence user still saw the bare forecourt figure under the map. It now uses priceTextAttributed with the style passed down from the list that opened the sheet (ContentView, StationsView, FavouritesView) — the same call the listing row makes, at the same @ScaledMetric(relativeTo: .title2) 22pt so it still scales with Dynamic Type.
"How Best Value works" gains a step-by-step section in plain English: the baseline and why it is the closest station by journey, the return trip and why the extra return travel can read larger than the one-way distance, the extra driving cost, the fuel-price saving, the total and its inversion when the drive costs more than the price saves, and where the minimum saving is set. Every statement matches the arithmetic in FuelSavingsCalculator. The sheet opens at 72% instead of 42% to give it room.
No calculation, ranking, wording or data source changed: comparisonLabel, priceTextAttributed and the shared FuelSavingsResult are the same calls they were.
The sheet leads with the station name and address inside the card, above the map, then a two-column facts row (fuel price on the left, distance and return on the right, split by a hairline) and the two station actions divided the same way. The Best Value block becomes a tinted card: verdict badge, the two figures the estimate is made of, the working and the total. "How Best Value works" moves to its own row below it, using the shared HowBestValueRow the Key sheet already shows.
Presentation only: every figure still comes from the shared sources (FuelStore.priceText, stationDistanceDisplay, FuelSavingsResult), so the sheet cannot disagree with the listing row, the widget or the Live Activity, and no calculation, ranking or freshness rule changed.
StationDistanceDisplay.returnLabel(unit:) and FuelSavingsFormat.extraTravelDistanceLabel(...) are split out of their caption forms so a surface printing the return or extra-travel figure on its own line takes it from the same place, confidence marker included; their existing output is unchanged, pinned by tests. FuelSavingsSummaryView is deleted - the sheet's card supersedes it and nothing referenced it.
DEBUG-only QA hooks: -qaConfigureSavings configures a Fuel Savings plan (the Best Value card and the Worth the Drive sort are gated on it), -qaDetailBottom scrolls to that card (defaultScrollAnchor is a no-op on a List) and -qaCopyPostcode holds the copied confirmation long enough to screenshot.
Two columns split by a 1pt hairline: identity on the left at a fixed 52%
share so rows line up when scrolling, price and savings on the right,
leading-aligned on one axis with the price dominant. The favourites star
sits under the station logo, freeing the width the pounds-and-pence price
needs to render in full rather than scaled or truncated.
Badges stay tinted rather than filled — BEST VALUE green, CHEAPEST blue,
none for nearest — and the verdict capsule is one shared view across the
listing, the detail sheet and the compact summary, so wording and colour
cannot drift between them.
Best Value's minimum saving moves from Alerts to Settings, Fuel Savings,
beside the fill size and MPG that produce the saving; the Alerts tab reads
it back instead of offering it twice. Its options are now 50p steps to £5
(was 50p/£1/£2/£5), so £2.50 and £3 are reachable, with a test pinning the
step, the ceiling and the store's string round-trip.
The verdict capsule scales to 0.7 before truncating. Measured on a 393pt
screen its copy is handed ~69pt while "Closest station" needs ~90pt, so the
old 0.8 floor could not reach it and rows showed "Closest stati..." instead.
Verified: Debug build clean, swift test 249/249.
The relay's price_updated is the maximum price_last_updated across the grades it maps, so it cannot vouch for the selected grade: stop using it to score, gate or warn about Best Value.
- FuelPriceFreshness is now station-level and display-only: one age per station, fresh/outdated/unknown/invalid, "May be outdated" past 30 days, with future-tolerance and non-finite guards.
- Best Value restores the closest-station-selling-the-selected-fuel baseline and its savings ranking; eligibility gating, eligible-first sorting and the unavailable banner are gone.
- Price age appears in the More info sheet only - no listing-row warnings, no extra banners.
- Copy reverted from "closest eligible station" to "closest station"; stale price-confidence strings removed, "May be outdated" added.
- Dormant per-grade timestamp plumbing removed, and regression tests added for every fuel type, missing/invalid/future stamps and the bundled offline dump.
- More info lists the fuel price first, with "Price updated" beneath it:
the price is what the row is about, the age qualifies it.
- The detail sheet stacks "vs closest eligible station" under the verdict
capsule, matching the listing rows, so the caption no longer shares a
line with the verdict it describes.
The verdict capsule shared a line with "vs closest eligible station"; the
caption's layoutPriority squeezed the capsule until it truncated
("Approx. £2.75 better off after tra…"), and in this sort mode the verdict
is the point of the row.
- The capsule now owns the line and the caption sits under it.
- The capsule text also shrinks rather than truncating at large Dynamic
Type sizes, since nothing competes with it for width.
- The detail sheet keeps its side-by-side layout: it has the room, and the
verdict there is the sheet's headline.
Dated pricing had crowded More info and the station rows, and most of the
extra copy described a distinction the data cannot make: every station
carries a single station-wide timestamp, so "grade-specific vs
station-wide" never varied in practice.
- More info shows one row, "Price updated 28h ago" (or "Not provided"),
replacing the separate station-report and fuel-update-time rows and the
blanket "price freshness is not confirmed" label.
- Rows and the detail sheet stay quiet when a saving is shown; only an
ineligible comparison explains itself. Provisional savings already read
as estimates from the capsule, so the fuel-named warning lines are gone.
- Freshness/eligibility logic is unchanged: it still gates the baseline and
still supports grade-specific timestamps for when the relay emits them.
- Tests updated; localisation keys for the removed copy dropped.
- RoadDistanceService builds route endpoints with MKMapItem(location:address:)
instead of the MKPlacemark path deprecated in iOS 26.
- LiveActivityManager updates through ActivityContent, replacing the
ActivityKit update(using:) call deprecated in iOS 16.2.
- The location-update hook no longer captures an unused state object; the
closure body already runs on self, so behaviour is unchanged.
- Station detail now separates the station's own report age from the
selected fuel's update time, so a recent station-wide report no longer
reads as an old price.
- Warning copy names the fuel and says which side is weak: the station's
price is not individually dated, or the baseline's is. The misleading
"unverified or older than 7 days" line is gone.
- Wording stays "Closest" throughout; new copy uses Unleaded / Premium /
Diesel rather than the internal grade codes.
- Localisation: new and updated keys for the added copy.
- Add FuelPriceFreshness: selected-fuel-aware eligibility plus a shared
comparison confidence, so a saving is presented as verified only when
both the candidate and the baseline pass the gate for the fuel on screen.
- Rank against the closest station with an eligible selected-fuel price
instead of the physically closest station, so a single stale neighbour
can no longer invalidate every comparison in the list. Ordinary Closest
sorting still includes every priced station.
- Keep ineligible prices visible, fall back to pump-price order, and label
Best Value unavailable when no comparison qualifies.
- Widget: same baseline and confidence path as the app.
- Tests: stale-closest baseline, alert baseline, eligibility policy,
boundary and missing-timestamp regressions.
The More info row went inside the Best Value card's `if let fuelSavings`, but the
Key sheet row was left ungated, so it stayed visible with Best Value switched off.
It is now gated on `fuelSavingsSettings.isConfigured` — exactly the condition
`savingsForStation` uses, i.e. the same gate as the card — so the two rows appear
and disappear together.
Verified on the simulator by toggling Best Value in Settings and scrolling the Key
sheet to its end (four drags, sheet still up and its footer in view each time):
- OFF: the row is absent at every scroll position, and the More info sheet shows
neither the card nor the row;
- ON: the row is present, and the More info card and its row are both back.
210 tests pass; Release builds.
The first onboarding screen showed the app icon inside AnimatedOnboardingIcon's
soft circle — a 10% tinted disc with an 18% ring around it. The wrapper now takes
`showsHalo`, defaulting to true so the other five pages and BestValueIntroView keep
theirs unchanged; the welcome page passes false.
Verified with before/after installs on the simulator:
- the icon's artwork is pixel-identical and unmoved (centre 603,661, 95 pt);
- the halo is gone — the tile's non-background footprint falls from the 118 pt
ring to exactly the 96 pt tile, and the ring pixels at r=59 pt lose their tint;
- page 1 differs only by the status-bar clock, so the other pages are untouched.
The copy below the icon tightens by ~11 pt: the page block is centred between two
spacers and the icon's container no longer contributes 22 pt of height. The page
dots and the Continue button do not move. The icon keeps its soft accent shadow.
The capsule label was just "Copied", which reads oddly above a row whose hint is
"Copies the postcode". It is now "Postcode copied".
Still centred over the address row (centre x 603 of a 1206 px screen) and still a
pure overlay: the bands above and below the capsule are pixel-identical while it
is up (no reflow), and the row stays tappable straight through it.
The "Copied" localisation key goes with its only use; "Postcode copied" replaces it.
The explanation used to be a section inside the Key sheet. It is a standalone
HowBestValueSheet now, opened from a tappable row with a chevron: at the bottom of
the Key sheet, and at the bottom of the More info sheet below the Best Value card.
Gating: the More info row sits INSIDE the same `if let fuelSavings` as the card it
follows, so it disappears with the feature. Verified with Best Value toggled off in
Settings: the More info sheet then shows neither the card nor the row. The Key
sheet row is deliberately ungated — that sheet is the legend and is reachable
whatever the feature is doing.
Copy is unchanged: the same Localizable.strings strings are reused, and the old
section header became the sheet's title. A DEBUG-only `-showBestValueInfo` hook
opens the sheet without a tap.
The confirmation belongs to the address row, so hovering it over the map read as
belonging to the map. It now overlays the address row itself, horizontally centred
on the address line, as .overlay(alignment: .center) on the row with
allowsHitTesting(false) still keeping the row tappable through the capsule.
Verified: with the capsule up, the OCR box sits at y 1189-1231 inside the address
band (map bottom is 1075), the tint blob is centred at x 602.5 against a screen
centre of 603, the row's ink runs outside the capsule footprint are byte-identical
to the idle frame, and a real tap on the capsule's own footprint still copies.
The address row is back to a single line: the copy glyph now sits on the address
line itself (trailing, plain glyph — the confirmation says it elsewhere), and the
always-reserved second line is gone.
The "Copied" confirmation is now a green-tinted capsule that floats over the
bottom of the map, directly above the address and horizontally centred. It is an
overlay with allowsHitTesting(false), so nothing reflows while it is up (verified:
the address row's ink, column for column, does not move) and the map's tap target
stays live underneath (verified: tapping where the capsule floats still opens
Apple Maps). A material base keeps it legible against map tiles, where a 14% wash
alone — the notice-capsule recipe — disappears. Timing is unchanged: 2s, then
fades, with the success haptic on copy.
The map already reads as its own block, so the row separator below it only
added clutter. Removed with .listRowSeparator(.hidden, edges: .bottom) on the map
row, leaving the Address/Distance and Distance/actions hairlines in place.
The map, the address, the distance, any notices and the Directions/Report issue
row now share a single section, in that order, with the buttons as the last row.
The list's own row hairlines separate them (inset like Address/Distance), so no
hand-rolled Divider is added — that would double the line.
The map loses .listRowInsets(EdgeInsets()) so it sits inset inside the card with
its rounded corners, aligned with the hairlines and text rather than butting the
card edges.
Directions/Report issue keep .buttonStyle(.borderless); verified with real
simulated taps in the merged card that each fires alone.
