SwiftUI app that:

• Authenticates with Firebase to obtain an ID token
• Talks to the backend at https://sfu-place-web-server.vercel.app
• Embeds a Unity AR scene with a transparent SwiftUI overlay

• macOS with Xcode 15+

• iPhone (iOS 16+), a USB cable, and Developer Mode enabled Settings → Privacy & Security → Developer Mode → On

• An Apple ID added in Xcode (for free “Personal Team” signing)

• Access to the same Firebase project used by the server:

  • Web API Key
  • A test email/password account

1. Server + Firebase keys In ContentView.swift, set:

   let api = APIClient(
     serverBase: "https://sfu-place-web-server.vercel.app",
     firebaseApiKey: "<FIREBASE_WEB_API_KEY>"
   )

   Replace "<FIREBASE_WEB_API_KEY>" and use valid credentials when signing in.

2. Camera permission (Info.plist) Add Privacy – Camera Usage Description: Used for AR camera feed.

3. Signing

   • Target Stormhacks 2025 → Signing & Capabilities:

     • ✔ Automatically manage signing
     • Team: Your Personal Team
     • Set a unique Bundle Identifier (e.g., com.yourname.stormhacks2025)

1. Plug in your iPhone → Trust computer → ensure Developer Mode is ON.

2. In Xcode:

   • Scheme: Stormhacks 2025
   • Destination: Your iPhone

3. Run (▶).

4. In the app:

   • Sign In → Create Surface → Send stroke (see logs in Xcode console).
   • Open AR Canvas (if you wired the AR screen) to see the Unity camera background with SwiftUI controls on top.

The server is HTTPS; no ATS exceptions required.
