Draw Idea

Draw Idea is a modern SwiftUI iOS game for two nearby players:

• Player 1 writes a sentence.
• Player 2 draws that sentence.
• The writer sees drawing updates in real time.

The app uses MultipeerConnectivity for local peer-to-peer communication (Bluetooth / peer-to-peer Wi-Fi / local Wi-Fi).

Features

• Two-player session flow:
  • Create session (host)
  • Join session (discover nearby host)
• Real-time collaboration:
  • Live stroke sync while drawing
  • Writer sees drawing updates instantly
• Role-based gameplay:
  • Sentence Writer
  • Drawer
• Drawing tools:
  • Color palette selection
  • Smooth freehand strokes
  • Done drawing action
• Round management:
  • New round reset
  • Keep playing multiple rounds in one session
• Connection UX:
  • Clear connection states (hosting, browsing, inviting, connecting, failed)
  • Dedicated “player joined” and continue actions
  • Reconnect session button
  • Auto reconnect attempt on app resume after lock/background disconnect
• Device behavior improvements:
  • Keeps screen awake during active hosting/session (isIdleTimerDisabled)
  • Tap anywhere to dismiss keyboard

App Flow

1. Open app on two devices.
2. Device A taps Create Session.
3. Device B taps Join Session and selects host.
4. Once connected, continue to role selection.
5. Pick opposite roles:
   • Writer enters sentence and sends it.
   • Drawer receives sentence and starts drawing.
6. Writer watches live drawing updates.
7. Drawer taps Done Drawing.
8. Tap New Round to play again.

Connectivity Notes

• Transport is automatically chosen by Apple via MultipeerConnectivity.
• Bluetooth is supported, but not forced exclusively (system may use Wi-Fi/P2P).
• If a lock/background interruption drops the link, the app can show reconnect and retry.

Permissions / Info.plist

The app includes required local-network Bonjour keys:

• NSLocalNetworkUsageDescription
• NSBonjourServices with "_drawidea._tcp."

Project Structure

• draw-idea/ContentView.swift - Main UI screens and flow
• draw-idea/SessionManager.swift - Session state + peer networking logic
• draw-idea/Models.swift - Shared models/enums for game + connection states
• Info.plist - App permissions and Bonjour settings

Requirements

• Xcode (recent version with SwiftUI support)
• Two physical iOS devices for realistic nearby testing

Run Locally

1. Open draw-idea.xcodeproj.
2. Build and run on two physical devices.
3. Accept Local Network permission when prompted.
4. Start one host and one joiner.

Known Limitations

• Session continuity across screen lock/background depends on iOS lifecycle behavior.
• MultipeerConnectivity transport selection is system-managed.
• Best experience is on real devices (simulator may be unreliable for nearby networking).
