Deploying the managed iOS app

VoiceCat's supported iOS client is the .NET 10 UIKit application in clients/apple/dotnet/VoiceCat.iOS. The checked-in scripts build its native Opus/RNNoise dependency, compile and sign the managed app and Swift ReplayKit extension, stage the bundle, install it, and launch it on a paired physical device.

Prerequisites

• macOS 27, Xcode 27, .NET SDK 10.0.401, and the matching iOS workload.
• An unlocked, trusted iPhone connected by USB or visible to Xcode over the network.
• Apple Development profiles for me.iamtalon.voicecat and me.iamtalon.voicecat.broadcast, both with App Group group.me.iamtalon.voicecat.

List available devices:

clients/apple/dotnet/deploy-ios-device.sh --list

Build, install, and launch

Set the Apple developer team explicitly. The .NET host and Xcode-built extension use separate build systems, and Xcode needs the team to select the extension profile.

export VOICECAT_DEVELOPMENT_TEAM=FJV8L966W4
clients/apple/dotnet/build-ios-device.sh --configuration Debug
clients/apple/dotnet/deploy-ios-device.sh \
  --device "Talon’s iPhone" \
  --configuration Debug \
  --no-build

The verified bundle is staged at dist/ios-managed-device/VoiceCat.iOS.app. Omit --no-build to build and deploy in one command. Add --console to attach the launch to device logs.

Confirm that the process stayed alive:

xcrun devicectl device info processes --device "Talon’s iPhone" | rg VoiceCat

Signing findings

The development team ID is FJV8L966W4. Do not infer it from the parenthesized suffix in an Apple Development certificate name; that value can identify the certificate holder and need not equal a profile's TeamIdentifier.

The extension wrapper uses automatic signing with installed profiles. If a profile is absent and Xcode has a valid signed-in developer account, permit Xcode to create or download it:

export VOICECAT_ALLOW_PROVISIONING_UPDATES=1

Leave that variable unset when valid profiles are already installed. A stale command-line Xcode account can otherwise make provisioning updates fail even though offline signing can succeed.

Troubleshooting

Stale CMake source path

After moving the native shim from dotnet/native to native/media, an old CMake cache can report a source-directory mismatch. Move the generated directories aside and rebuild:

mv dotnet/artifacts/native-build-ios-arm64-cmake /tmp/
mv dotnet/artifacts/native-build-iossimulator-arm64-cmake /tmp/

Locked restore reports changed runtime identifiers

The managed libraries' lock files must include ios-arm64 and iossimulator-arm64. Regenerate them after runtime changes, then verify that dependency versions did not change:

/usr/local/share/dotnet/dotnet restore \
  clients/apple/dotnet/VoiceCat.iOS/VoiceCat.iOS.csproj \
  -p:VoiceCatIosStatic=true \
  --force-evaluate

Developer disk image cannot be mounted

CoreDevice errors 10003 or 12040 mean the phone locked. Unlock it, keep the display awake, and rerun deployment with --no-build.

Verified hardware result

On 2026-09-19, the Debug build completed with .NET 10.0.401 and Xcode 27.0. The host and ReplayKit extension were signed under team FJV8L966W4, installed wirelessly on Talon's iPhone, launched as me.iamtalon.voicecat, and remained in the device process list. Audio, background/lock behavior, Bluetooth, ReplayKit, ScreenCaptureKit, and VoiceOver remain separate manual hardware gates.
