# Screens (working title)

A VNC / RFB remote-desktop client for iPhone and iPad, modeled on [Screens by Edovia](https://www.edovia.com/en/screens/). See `/Users/treyt/.claude/plans/i-want-to-make-sprightly-pike.md` for the full plan.

> The name "Screens" is owned by Edovia. Pick a different App Store name before any public release.

## Layout

```
Screens/
├── Screens/           # iOS app target (thin shell: @main, RootView, AppStateController)
├── Packages/
│   ├── VNCCore/       # Protocol + transport + storage. Tested with `swift test`.
│   └── VNCUI/         # SwiftUI views + UIKit framebuffer. Tested in-simulator.
├── Project.yml        # xcodegen project definition — generates the .xcodeproj
├── README.md
└── .gitignore
```

## Setup

1. Install [xcodegen](https://github.com/yonaskolb/XcodeGen):
   ```sh
   brew install xcodegen
   ```
2. Generate the Xcode project from the repo root:
   ```sh
   xcodegen generate
   ```
3. Open `Screens.xcodeproj` in Xcode 16+. First open resolves the RoyalVNCKit SPM dependency.
4. Select an iOS 18 simulator (or a signed device) and run.

## Testing

```sh
# Fast unit tests (no simulator)
cd Packages/VNCCore && swift test
cd Packages/VNCUI   && swift test

# Full app + UI tests (simulator)
xcodebuild -project Screens.xcodeproj -scheme Screens -destination 'platform=iOS Simulator,name=iPhone 16' test
```

## Phase 0 status

Scaffold only. Tapping a saved connection starts a `SessionController` but it only opens the TCP socket — no RFB handshake yet. Phase 1 wires RoyalVNCKit into `SessionController` and implements framebuffer rendering.

## Dependencies

- [RoyalVNCKit](https://github.com/royalapplications/royalvnc) (MIT) — RFB protocol, encodings, auth.
- Apple first-party only: `Network`, `SwiftData`, `Security`, `UIKit`, `SwiftUI`, `Observation`.
