Two follow-ups after the iOS Rust build went green at 5de6ecc:
1. cpal-side framing constants (SAMPLE_RATE / FRAME_SAMPLES /
MAX_OPUS_FRAME) are dead code in the current iOS commit
because the VPIO callbacks are still no-op stubs and don't
reach the constants yet (commits 3 + 4 will). They are
genuinely live on every other platform via the cpal capture
pipeline. Mark each with #[allow(dead_code)] and add a
comment pointing at the commits that will reactivate them on
iOS, instead of cfg-gating per-platform (the constants are
framing invariants of the engine itself, not per-backend
details).
2. ios/Podfile.lock regenerated on the Mac via 'pod install'
to register package_info_plus (0.4.5) which landed in
97a6ba6. Without this regen the Xcode build fails with
'The sandbox is not in sync with the Podfile.lock' because
Xcode's CocoaPods integration check sees a new plugin in
pubspec.yaml that has no matching Pod entry. Five pods now
in the lockfile: Flutter, audio_session, chanora_bridge,
connectivity_plus, package_info_plus.
Build counter 61 -> 62 — the About dialog will display
v1.0.0-rc.8+62 so the user can confirm the build under test
matches this commit (the previous build said +61).
User reported: the 'output device' picker only listed AirPlay
destinations (other iPhones / AirPlay speakers / AppleTV) and not
the speaker / iPhone receiver / AirPods / wired headset choices.
Root cause: audio_router 1.1.1's iOS path uses AVRoutePickerView,
which is Apple's **AirPlay** picker UI \u2014 by design it only lists
AirPlay-eligible output destinations, NOT the input/output route
choices we need (speaker vs receiver vs Bluetooth HFP vs wired).
AVRoutePickerView is the right UI for 'cast audio elsewhere'; for
'pick how I hear / talk' (VoIP) the right primitive is direct
AVAudioSession calls.
Fix: replace audio_router with audio_session 0.2.3 (Ryan Heise,
verified publisher, 865k downloads, MIT). audio_session exposes:
* AVAudioSession.availableInputs \u2014 enumerate every real input
port: builtInMic, bluetoothHfp, bluetoothA2dp, headsetMic
(wired), usbAudio, carAudio, airPlay.
* AVAudioSession.currentRoute \u2014 .inputs + .outputs of the
active route.
* AVAudioSession.setPreferredInput(port) \u2014 switch the input
(HFP / wired / USB / car audio also move output to themselves).
* AVAudioSession.overrideOutputAudioPort(.speaker | .none) \u2014
toggle built-in speakerphone vs receiver/earpiece.
* AVAudioSession.routeChangeStream \u2014 live notifications when
the user plugs / unplugs / connects a device while the picker
is open.
This is exactly the same primitive Discord, WhatsApp, FaceTime
use for their VoIP audio chooser. No native UI plugin needed.
New widgets in voice_compact.dart:
* _AudioOutputTile: shows the active output port name (Speaker /
iPhone / AirPods / 'Phil's Wired Headset' / etc.) with the
matching icon. Subscribes to routeChangeStream for live
updates. Tap opens _AudioOutputPickerSheet.
* _AudioOutputPickerSheet: bottom sheet with 'Choose audio' title
and a Discord-style list:
- Speaker (volume_up)
- iPhone (phone_in_talk; the receiver/earpiece)
- <BT name> (bluetooth_audio)
- <Wired headset> (headset)
- <USB / Car> (usb / directions_car)
Selected row is highlighted + has a check mark. Tap routes:
- Speaker -> overrideOutputAudioPort(.speaker)
- iPhone -> overrideOutputAudioPort(.none) + setPreferredInput(builtInMic)
- External -> overrideOutputAudioPort(.none) + setPreferredInput(port)
* _PickerRow: shared row widget with selected/check styling.
AppDelegate.swift is unchanged: the manual AVAudioSession
.setCategory(playAndRecord / .voiceChat) we already do at launch
(0466000 / 4ee2b38) is fully compatible with audio_session \u2014 the
plugin only adds Dart-side accessors over the same underlying
AVAudioSession singleton.
Removed l10n keys not used anymore (audioRouteUsb was already gone).
Kept audioRouteSpeaker / Receiver / Bluetooth / WiredHeadset /
CarAudio / Airplay / Unknown \u2014 all still used by the new picker.
flutter analyze: 6 pre-existing Radio deprecation infos (unchanged).
flutter build ios --release --no-codesign: 54.9 s, Runner.app
30.4 MB (+200 KB vs audio_router build).
Two user-reported issues addressed:
1. 'on supported devices such as iphone or android user should be
able to select audio device such as speaker or airpods or phone'
2. 'the bottom folder is duplicated with the app bar settings'
Issue 1 \u2014 audio output route picker:
Added the audio_router 1.1.1 plugin (MIT, supports iOS + Android)
which renders the platform-native picker:
* iOS: Apple AVRoutePickerView system sheet \u2014 the same UI as
Control Center's audio chooser. Lists Speaker / iPhone receiver /
AirPods / connected Bluetooth devices / AirPlay / CarPlay.
System manages the device list; we don't have to track route
changes manually.
* Android (post-rc.8 when we wire the platform): Material Design 3
dialog backed by AudioManager.setCommunicationDevice() with
SCO Bluetooth + USB headsets filtered for VoIP.
The picker prerequisite documented by the plugin (audio session
must be playAndRecord/voiceChat before the picker fires) is already
satisfied by our AppDelegate.swift configuration from commit 0466000.
The new _AudioOutputTile widget in voice_compact.dart subscribes to
AudioRouter.currentDeviceStream so the row label + icon auto-update
when the user plugs in headphones, connects AirPods, etc. \u2014 no
manual KVO observation needed.
Tile is mobile-only (Platform.isIOS || Platform.isAndroid). Desktop
hosts continue to use the system mixer; the tile is hidden.
Plugin caveat: the published enum AudioSourceType has no .usb
variant (despite README mentioning USB support). We map only the
seven real enum cases: builtinSpeaker / builtinReceiver / bluetooth /
wiredHeadset / carAudio / airplay / unknown.
Issue 2 \u2014 collapse voice controls into the single modal sheet:
The AppBar gear icon (Icons.tune) that opened VoiceSettingsDialog
was removed. It duplicated the configuration entry point that the
status chip \u2192 modal-sheet path already provides, and the user found
that duplication confusing on a phone-narrow screen where AppBar
real estate is precious.
The voice modal sheet (showVoiceDetailsSheet) is now the **single**
voice-controls surface on mobile, with layout (top to bottom):
1. Audio output route picker tile (iOS / Android only) \u2014 new.
2. Mode + bind / release-tail recap (display only).
3. 'Adjust mode & release tail' OutlinedButton that closes the
sheet and opens the same VoiceSettingsDialog the gear icon
used to open. One config form, not two.
4. Mic level meter.
5. TX / RX frame counts + mic state.
6. PTT capability badge (desktop only).
Sheet title renamed from 'Voice settings' (which collided with the
gear-icon tooltip) to 'Voice'. New l10n keys: voiceSheetTitle,
voiceAdjustSettings, audioOutputLabel, audioRoute{Speaker,Receiver,
Bluetooth,WiredHeadset,CarAudio,Airplay,Unknown}. en + zh translated.
Build: flutter build ios --release --no-codesign clean, 50.5 s,
Runner.app 30.2 MB (+200 KB from audio_router). flutter analyze
clean (6 pre-existing Radio.groupValue deprecation infos in
voice_settings.dart, unchanged).
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
chanora_bridge.framework generated at
apps/chanora_flutter/ios/Frameworks/chanora_bridge.framework
Install name: @rpath/chanora_bridge.framework/chanora_bridge
flutter build ios --release --no-codesign 12.7 s
-> Runner.app 29.9 MB (was 16.9 MB without the bridge)
-> Runner.app/Frameworks/chanora_bridge.framework present
alongside Flutter.framework, App.framework,
connectivity_plus.framework, objective_c.framework.
DEC-025: iOS / iPad officially in scope for P0.
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.
Building the bridge for `aarch64-apple-ios` failed in two ways with
the previous TLS stack:
1. `aws-lc-sys` (transitive: rustls -> aws-lc-rs -> aws-lc-sys)
does not cross-compile cleanly to iOS — the build produced
undefined symbols for architecture arm64 (mldsa44, ec_GFp_mont,
etc).
2. `audiopus_sys` linked against the wrong iOS runtime version,
missing `___chkstk_darwin`.
Following the rustls-platform-verifier docs and the standard Rust+
iOS+TLS pattern used by 1Password / Signal / rustup / Bitwarden,
this commit swaps the TLS provider to **native-tls** so each
platform picks its own:
* macOS + iOS -> Security.framework (no external C deps)
* Windows -> SChannel
* Linux/BSD -> system OpenSSL
Changes:
crates/chanora_protocol/Cargo.toml
crates/chanora_audio/Cargo.toml
* Drop `default-tls` from tsclientlib's features. The remaining
`audio` feature is what we actually use; default-tls was a
reqwest convenience that picked rustls+aws-lc-rs.
* Add a direct `reqwest` dep with `default-features = false,
features = ["charset", "http2", "native-tls"]`. Cargo's
workspace feature unification carries this through the
transitive `tsclientlib -> reqwest` chain.
apps/chanora_flutter/ios/Podfile
* Uncomment `platform :ios, '13.0'` so CocoaPods stops emitting
the implicit-platform warning and Xcode's iOS deployment-
target check is honored.
apps/chanora_flutter/ios/Podfile.lock
* Generated by `pod install` after the platform pin. Committed so
iOS builds on other developer machines pull the exact same Pod
versions.
apps/chanora_flutter/ios/Runner.xcodeproj/project.pbxproj
apps/chanora_flutter/ios/Runner.xcworkspace/contents.xcworkspacedata
* CocoaPods auto-integration: adds Pods_Runner.framework +
Pods_RunnerTests.framework references and the Pods xcconfig
file references. Standard `pod install` output; reviewing the
diff shows only Pod-bookkeeping additions, no signing or
target-config drift.
Verified end-to-end on the M1 Mac (coder@100.118.130.73):
cargo build --release -p chanora_bridge 29.09 s
cargo build --release --target aarch64-apple-ios 24.32 s
(with IPHONEOS_DEPLOYMENT_TARGET=13.0 and
CMAKE_POLICY_VERSION_MINIMUM=3.5 in the env to satisfy the
audiopus_sys cmake invocation; documented as a P1 build-glue
follow-up.)
flutter build ios --release --no-codesign ok
Built build/ios/iphoneos/Runner.app (16.9 MB)
Xcode GUI build of Runner.xcworkspace ok
(after the user opened Runner.xcworkspace, NOT
Runner.xcodeproj, and Clean Build Folder.)
Tests on macOS unchanged: chanora_audio 34 / 0 / 0.
