Follow-up to #452, from dogfooding the merged build on a real iPhone.
A mod fused into game.love sits in the read-only app bundle: the mod
manager's Delete can't remove it and it reappears every launch, and an
imported newer version can never fully replace it. iOS now packs no
mods, matching every other platform - mods install as .zips at runtime
with a real install/upgrade/delete lifecycle.
With nothing fusing it, mods/pokewalker moves out of this tree to its
canonical home, https://github.com/mresnick67/Gen1ReComp-Pokewalker
(already at 0.2.0 there with move learning and a paged credit dialog;
in-tree 0.1.0 was stale). docs/ios-install.md points at it. The
event:save.loaded coverage-debt entry returns to gate_meta_coverage:
its coverage came from the mod's test suite and leaves with it.
Local reproduction of the ci workflow on this branch: all tiers, mod
lint, fingerprint + meta-coverage gates green.

Makes the iOS build a first-class citizen: ROM/mod/save import through
the system document picker (the README's missing "UIDocumentPicker
handoff"), Files-app drop-in support, and an opt-in Apple Health
step-sync seam consumed by a new gallery mod (Pokewalker).
Native layer (mobile/ios/native/, wired by mobile/ios/patch_love_src.py
on every build, so the fetched love-src tree stays pristine + re-patchable):
- GRPickerBridge.swift: love.system.pickFile("rom"|"mod"|"sav") and
love.system.createFile on iOS with the same contract as love-android's
SAF picker (picked_rom.gb / picked_mod.zip / picked_save.sav /
export_done.flag in the save dir). Reached from wrap_System.cpp via the
ObjC runtime, so liblove needs no Swift interop.
- GRBootstrap.m: sweeps .gb/.gbc/.zip/.sav dropped in Documents (Files
app / Finder sharing) into the save dir on every activation;
UIFileSharingEnabled + LSSupportsOpeningDocumentsInPlace in the plist
overlay. Drop a ROM, open the app, it imports with zero taps.
- GRHealthBridge.swift: love.system.syncHealthSteps() -> read-only
HealthKit step query anchored to the last sync, delivered as
steps_pending.json (merge-not-overwrite). HealthKit entitlement +
usage description included.
Lua:
- RomImporter: iOS rides the Android mobile flows; a 0.5s poll consumes
picker deliveries (iOS pickers are in-process modals, so the Android
refocus rescan never fires); failed pick copies surface as an
on-screen notice via pick_error.txt.
- main.lua: on iOS, stop forwarding touchpressed to the Importer - LOVE
already synthesizes a mousepressed for the primary touch, and the
resulting same-frame double-present made the document picker
auto-dismiss with zero documents (silent import failure).
- mods/pokewalker: opt-in Pokewalker mod (manifest v2, MECHANIC,
permissions declared, mod.card, CHANGELOG, headless test suite 9/9,
modkit validate --base imported + lint clean). Fused into iOS
game.love only; loads dormant anywhere without the bridge.
Build (scripts/build_ios.sh):
- Fix Xcode 26: the global PRODUCT_NAME override also renamed liblove.a
and broke the app link; the app bundle is renamed after the build
instead.
- Fix nondeterministic pack failures: grep -q + pipefail races SIGPIPE
on the game.love content checks.
- Simulator builds sign ad-hoc so entitlements embed (HealthKit works in
the simulator).
- Device builds: signing team auto-detected from the keychain,
CODE_SIGN_STYLE=Automatic + -allowProvisioningUpdates for CLI-only
provisioning, per-team derived bundle ID (explicit App IDs are
globally unique, so third parties can't sign the project default),
gitignored mobile/ios/bundle_id.local pin, and --install to push to a
connected iPhone.
- docs/ios-install.md: a zero-knowledge walkthrough from bare Mac to
playing on an iPhone.
Backward compatibility: no behavior change on desktop or Android. The
new love.system functions exist only under LOVE_IOS; RomImporter's
mobile flag simply includes iOS alongside Android; the main.lua change
is iOS-gated; the Pokewalker mod is packed only by the iOS build script
and its option defaults off.
Verified on an iPhone 17 Pro simulator and an iPhone 16 Pro device:
scripted ROM import to title screen, Files-drop zero-tap import,
picker-driven mod install and save import/export, HealthKit permission
sheet + step credit (4000 steps -> +200 EXP at the default rate through
the engine growth curve).
