# pi-remote iOS

Native iOS app for the [pi-remote-control](https://git.vpsj.de/jay/pi-remote-control) sidecar.

## Requirements

- Xcode 16.4+
- iOS 17.0+ device
- pi-remote-control sidecar running (Phase 1)

## Building

```bash
# Open in Xcode (first time: Xcode downloads device support files automatically)
open piRemote.xcodeproj

# Or via CLI (after first Xcode open with device connected):
xcodebuild build -project piRemote.xcodeproj -scheme piRemote \
  -destination "platform=iOS,name=<YourPhone>" \
  CODE_SIGNING_STYLE=Automatic DEVELOPMENT_TEAM=KNXX8R3648
```

## Dependencies (via SPM)

- [SwiftTerm](https://github.com/migueldeicaza/SwiftTerm) — terminal emulator
- [Starscream](https://github.com/daltoniam/Starscream) — WebSocket client

## Apple Developer setup (one-time)

1. In [Apple Developer Portal](https://developer.apple.com/account):
   - Create App ID: `de.vpsj.pi-remote`, enable **Push Notifications**
   - Generate an **APNs Auth Key** (`.p8`) — *download once, keep safe*
   - Note your **Key ID** and **Team ID** (`KNXX8R3648`)
2. Copy `.p8` key to `~/.local/share/pi-remote/apns/AuthKey_<KeyID>.p8`
3. Update `[apns]` section in pi-remote-control config
