# Build Script Improvements

**Date:** 2025-11-13  
**Status:** ✅ **FIXED**

---

## Issues Fixed

### 1. Missing Build Folder ✅

**Problem:**
- Script was looking for `build` directory: `find build -name "*.app"`
- Xcode actually builds to `DerivedData`: `~/Library/Developer/Xcode/DerivedData/App-*/Build/Products/`

**Solution:**
- Updated script to search in `DerivedData`:
  ```bash
  DERIVED_DATA_PATH="$HOME/Library/Developer/Xcode/DerivedData"
  APP_PATH=$(find "$DERIVED_DATA_PATH" -name "App.app" -path "*/Build/Products/Debug-iphonesimulator/*" -type d 2>/dev/null | head -1)
  ```

**Result:** ✅ App path now correctly detected

---

### 2. Simulator Not Launching ✅

**Problem:**
- Script only built the app, didn't boot or launch simulator
- No automatic deployment after build

**Solution:**
- Added automatic simulator boot detection and booting
- Added Simulator.app opening if not already running
- Added boot status polling (waits up to 60 seconds)
- Added automatic app installation
- Added automatic app launch (with fallback methods)

**Implementation:**
```bash
# Boot simulator if not already booted
if [ "$SIMULATOR_STATE" != "Booted" ]; then
    xcrun simctl boot "$SIMULATOR_ID"
    open -a Simulator  # Open Simulator app
    # Wait for boot with polling
fi

# Install app
xcrun simctl install "$SIMULATOR_ID" "$APP_PATH"

# Launch app
xcrun simctl launch "$SIMULATOR_ID" com.timesafari.dailynotification.test
```

**Result:** ✅ Simulator now boots and app launches automatically

---

## Improvements Made

### Boot Detection
- ✅ Polls simulator state every second
- ✅ Waits up to 60 seconds for full boot
- ✅ Provides progress feedback every 5 seconds
- ✅ Adds 3-second grace period after boot detection

### App Launch
- ✅ Tries direct launch first
- ✅ Falls back to console launch if needed
- ✅ Provides manual instructions if automatic launch fails
- ✅ Handles errors gracefully

### Error Handling
- ✅ All commands have error handling
- ✅ Warnings instead of failures for non-critical steps
- ✅ Clear instructions for manual fallback

---

## Current Behavior

1. ✅ **Builds** the iOS test app successfully
2. ✅ **Finds** the built app in DerivedData
3. ✅ **Detects** available iPhone simulator
4. ✅ **Boots** simulator if not already booted
5. ✅ **Opens** Simulator.app if needed
6. ✅ **Waits** for simulator to fully boot
7. ✅ **Installs** app on simulator
8. ✅ **Launches** app automatically

---

## Known Limitations

### Launch May Fail
- Sometimes `xcrun simctl launch` fails even though app is installed
- **Workaround:** App can be manually launched from Simulator home screen
- **Alternative:** Use Xcode to run the app directly (Cmd+R)

### Boot Time
- Simulator boot can take 30-60 seconds on first boot
- Subsequent boots are faster
- Script waits up to 60 seconds, but may need more on slower systems

## Testing

**Command:**
```bash
./scripts/build-ios-test-app.sh --simulator
```

**Expected Output:**
```
[INFO] Build successful!
[INFO] App built at: /Users/.../DerivedData/.../App.app
[STEP] Checking simulator status...
[STEP] Booting simulator (iPhone 17 Pro)...
[STEP] Waiting for simulator to boot...
[INFO] Simulator booted successfully (took Xs)
[STEP] Installing app on simulator...
[INFO] App installed successfully
[STEP] Launching app...
[INFO] ✅ App launched successfully!
[INFO] ✅ Build and deployment complete!
```
