Screens (working title)

A VNC / RFB remote-desktop client for iPhone and iPad, modeled on Screens by Edovia. 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.

Setup

1. Install xcodegen:

   brew install xcodegen
   

2. Generate the Xcode project from the repo root:

   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

# 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 (MIT) — RFB protocol, encodings, auth.
• Apple first-party only: Network, SwiftData, Security, UIKit, SwiftUI, Observation.
