# Voice — iOS client for Hope Voice
|
|
|
|
Native SwiftUI iOS app (iOS 17+) that talks to the [Hope Voice](https://github.com/) 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](PLAN.md) and [docs/DEVICE_TESTING.md](docs/DEVICE_TESTING.md).
|
|
|
|
## Prerequisites
|
|
|
|
- Xcode 16+ (Swift 6), iOS 17 simulator or a real iPhone on the LAN.
|
|
- [xcodegen](https://github.com/yonaskolb/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
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
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.
