Two iOS bugs with the same shape: unconditional rebuilds where a conditional check belongs. The audio graph was torn down on every unintentional disconnect and every foreground transition. A lost connection ran the same teardown as an explicit disconnect, deactivating the AVAudioSession and so dropping the Bluetooth HFP link for a transport blip, and foregrounding always called Reconfigure even though the `audio` background mode keeps the graph live. Both cost seconds of dead audio on a headset. Split "session ended" from "transport blipped". Detach unbinds the client but keeps the session, graph, and route, so a reconnect rebinds to a live HFP link; the route is parked on stream id 0 so capture cannot feed the next connection a stream it never announced. StartListening reuses a running graph, StartMicrophone reuses a running tap of the same width, and Reconfigure gained a non-forcing mode that no-ops when tap presence, channel width, and voice processing all still match. Foregrounding now ensures the graph is running and only reconfigures if it actually stopped. Route changes, media-services resets, and the stall watchdog still force a full rebuild. Every list also reloaded on a model event raised 20 times a second by the microphone level timer. ReloadData recreates the accessibility element tree, so VoiceOver explore mode re-announced the row under a dragging finger and a double tap landed on an element that no longer existed. No controller ever unsubscribed, so popped controllers kept reloading too. Move the level to its own LevelChanged event, and reload lists through ListRefresher, which subscribes only while on screen and only reloads when the rendered content signature changed. The voice bar publishes its accessibility value on 5% steps, MoveUserController reloads just its two checkmark rows, and the chat transcripts skip reassigning identical text. The changed logic sits on UIKit and AVFoundation types the net10.0 test project cannot reference, so this carries no tests; the Bluetooth reconnect and foreground paths need device verification.
Apple clients
VoiceCat.Mac and VoiceCat.iOS are .NET 10 AppKit and UIKit clients over the shared managed
core. The ReplayKit upload extension under native/apple/broadcast remains Swift because it
runs under the extension memory limit and writes the versioned shared audio ring.
Build on macOS with Xcode and the pinned .NET workloads:
./scripts/build-native.ps1
./scripts/build-native-ios.sh
dotnet restore clients/apple/VoiceCat.Apple.slnx
dotnet build clients/apple/VoiceCat.Apple.slnx -c Debug --no-restore
Use publish-macos.sh --dry-run to validate a local ad-hoc macOS bundle. The dry-run build does
not enable hardened runtime because ad-hoc signatures have no Team ID and cannot satisfy macOS
library validation. The script normalizes nested signatures and installs the verified bundle at
both VoiceCat.Mac/bin/Release/net10.0-macos27.0/osx-arm64/VoiceCat.app and
VoiceCat.Mac/bin/Release/distribution/VoiceCat.app. Distribution builds remain hardened and
require VOICECAT_CODESIGN_IDENTITY; optional notarization uses APPLE_ID, APPLE_TEAM_ID, and
APPLE_APP_PASSWORD.
For a physical iOS device, use build-ios-device.sh and deploy-ios-device.sh. The host and
ReplayKit extension require signing profiles with App Group group.me.iamtalon.voicecat.
Hardware validation must cover VoiceOver, background and lock behavior, interruptions, route
changes, Bluetooth, ReplayKit, and iOS 27 ScreenCaptureKit audio.
For iOS voice stability, leave a call joined with the microphone active for at least 30 minutes
and confirm speech stays clear and VC_AUDIO reports no growing feedDrops. While still joined,
toggle Wi-Fi off and on, switch between Wi-Fi and cellular, and confirm the app stays open,
reconnects, and restores the voice session. Repeat with mono, stereo, and voice processing.
The iOS remote-user manual gate must also cover Users → user detail → independent microphone and screen-audio gain/mute controls, microphone receive noise reduction, the no-active-stream state, and Private Chats → conversation → User/audio settings. Repeat the navigation with VoiceOver and disconnect the remote user while its detail and conversation views are open.
App Store builds use the same device builder with --configuration Release. Set
VOICECAT_BUILD_NUMBER, VOICECAT_DISPLAY_VERSION, VOICECAT_DEVELOPMENT_TEAM, the host
VOICECAT_CODESIGN_KEY/VOICECAT_CODESIGN_PROVISION pair, and the extension
VOICECAT_BROADCAST_CODESIGN_KEY/VOICECAT_BROADCAST_CODESIGN_PROVISION pair. The host and
extension profiles must both be App Store Connect profiles and include the shared App Group.
The complete TestFlight workflow is documented in docs/apple-ios-release.md. The shared ring
contract is documented in docs/broadcast-ring-format.md.
