The podspec's prepare_command only fires on `pod install`. Once a
framework was generated, Rust source changes were silently ignored
because Xcode kept re-bundling the stale framework into Runner.app.
Manifested today as: ran `cargo build --release --target
aarch64-apple-ios` to pick up the lenient voice_join fix, ran
`flutter build ios`, but Runner.app/Frameworks/chanora_bridge.
framework/chanora_bridge was still the framework from the previous
pod install (16:10) not the just-built 18:30 dylib.
Add an explicit `script_phase` to the podspec that re-runs:
1. cargo build --release --target aarch64-apple-ios -p chanora_bridge
2. cp dylib into Frameworks/chanora_bridge.framework/chanora_bridge
3. install_name_tool -id @rpath/...
on every Xcode 'Build', not just on pod install. The script short-
circuits when the framework's binary mtime is newer than the cargo
output (fast no-op on incremental builds where Rust didn't change).
Side effect: every Xcode build now invokes cargo, which can take
~5 s on a warm cache and ~1 min cold. This is the right trade-off
because the previous behavior silently shipped stale Rust code.
iOS rejects loose .dylib loads (`dlopen` of any path outside the
app bundle is sandboxed), so a Flutter-Rust bridge has to ship
inside the .app as an Embed-and-Sign framework that
flutter_rust_bridge's runtime loader can dlopen via its default
`chanora_bridge.framework/chanora_bridge` lookup path.
This commit wires the bridge into the iOS build via a CocoaPods
podspec. Same role Cargokit plays for other Flutter+Rust setups,
done by hand against this repo's layout to avoid the Cargokit
vendoring footprint that was previously dropped.
apps/chanora_flutter/ios/chanora_bridge.podspec
New file. `prepare_command` invokes
`cargo build --release --target aarch64-apple-ios -p chanora_bridge`
with IPHONEOS_DEPLOYMENT_TARGET=13.0 +
CMAKE_POLICY_VERSION_MINIMUM=3.5 (satisfies audiopus_sys's
cmake invocation on modern CMake 4.x), then wraps the
produced libchanora_bridge.dylib into
chanora_bridge.framework with an Info.plist that declares
iPhoneOS / MinimumOSVersion=13.0, and rewrites LC_ID_DYLIB
to @rpath/chanora_bridge.framework/chanora_bridge.
`vendored_frameworks` exposes the result to CocoaPods, which
integrates it into Runner.xcodeproj with Embed & Sign
automatically. No Xcode UI edits required.
apps/chanora_flutter/ios/Podfile
Add `pod 'chanora_bridge', :path => '.'` to the Runner
target.
apps/chanora_flutter/ios/Podfile.lock
Generated by `pod install` after the pod was added. Pins
chanora_bridge 1.0.0 + checksum so iOS builds on other
developer machines pull the same framework version.
.gitignore
Add `/apps/chanora_flutter/ios/Frameworks/` so the
~13 MB built framework (regenerated on every pod install) is
not committed.
Verified end-to-end on the M1 Mac (coder@100.118.130.73):
pod install ok

Notes for owners installing on physical iOS devices:
The Personal Apple Team in Xcode requires a unique
PRODUCT_BUNDLE_IDENTIFIER (the default 'app.chanora.chanoraFlutter'
may already be claimed in the App Store registry). Set this
locally in Xcode -> Runner target -> Signing & Capabilities ->
Bundle Identifier (e.g. yourname.chanora.chanoraFlutter); do
NOT commit that change back since it is user-specific.
