Voice — iOS client for Hope Voice

Native SwiftUI iOS app (iOS 17+) that talks to the Hope Voice agent: voice/text conversation, transcript history, voice & model pickers, and a background-tasks panel. Uses hope-voice-api.

Status: Core functionality is implemented and verified in simulator to the extent the environment allows. Full device qualification (mic capture, interruption behavior) remains pending. The native Talk/Activity redesign is implemented — see PLAN.md and docs/DEVICE_TESTING.md.

Prerequisites

• Xcode 16+ (Swift 6), iOS 17 simulator or a real iPhone on the LAN.
• xcodegen (brew install xcodegen).
• The voice container running on Unraid (LiveKit + token server).
• Mic: the simulator mic is unreliable in this environment (CoreAudio -4010, 0 input channels) — voice mode needs a real device. If the simulator was wiped, grant permission first: xcrun simctl privacy booted grant microphone dev.shane.voice.

Build & run

xcodegen generate   # regenerate Voice.xcodeproj after file changes
xcodebuild -project Voice.xcodeproj -scheme Voice_iOS \
  -destination 'generic/platform=iOS Simulator' build

The scheme is Voice_iOS (not Voice). Bundle id: dev.shane.voice. To run in the simulator, use Xcode or xcrun simctl with the built app.

Server configuration

Default base URL is https://192.168.86.2:9178 (see Sources/App/SettingsStore.swift). Change it at runtime in Settings → Server URL (the app disconnects and recreates the session when idle). The app derives the LiveKit signaling endpoint from this base URL.

TLS cert pinning

The deployment uses a persistent self-signed cert. The entrypoint regenerates it if missing or issued for a different IP. The pinned SHA-256 in Sources/Networking/TLSPinning.swift must match after any actual cert rotation:

openssl s_client -connect 192.168.86.2:9178 </dev/null 2>/dev/null \
  | openssl x509 -outform der | openssl dgst -sha256

Paste the new hash into TLSPinning.pinnedCertSHA256Hex. Until you do, token calls fail with a pin mismatch (not a network error).

Features

• Conversation — LiveKit room with the Hope agent; voice mode (mic + TTS) and text mode (composer), toggleable and persisted. State machine (idle/connecting/listening/thinking/ speaking) driven by audio levels, with a compact status indicator and mic meter.
• Transcripts — partials updated in place, finals with timestamps, delivery-marker stripping, last-50 history persisted to UserDefaults, clear button.
• Voice & model pickers — 13 Azure TTS voices; LLM models from the agent's models message. Both persist and sync on join (set_voice/set_model).
• Activity tab — live task_event updates (steps, result, error) with an active count badge on the tab.

Known limitations

• Simulator mic: CoreAudio returns -4010 (no usable input source) in this environment; voice capture must be verified on a real device. Text mode works in the simulator.
• Cert pin rotation: see above — re-export the pin after each server cert regeneration.
• LiveKit signaling uses plain ws://192.168.86.2:7880 (not wss) because the Swift SDK cannot trust the self-signed cert on its WebSocket; token calls still go over pinned TLS.
