## Core Workflows

### 1. Prepare for TestFlight

```bash
# Validate project configuration
xcodebuild -project MyApp.xcodeproj -scheme MyApp -showBuildSettings

# Increment build number
agvtool new-version -all $(( $(agvtool what-version -terse) + 1 ))

# Set marketing version
agvtool new-marketing-version 1.0.0
```

### 2. Archive Build

```bash
# Clean build folder
xcodebuild clean -project MyApp.xcodeproj -scheme MyApp

# Archive for App Store
xcodebuild archive \
  -project MyApp.xcodeproj \
  -scheme MyApp \
  -configuration Release \
  -archivePath ./build/MyApp.xcarchive \
  -destination "generic/platform=iOS"
```

### 3. Export Archive

```bash
# Export for App Store / TestFlight
xcodebuild -exportArchive \
  -archivePath ./build/MyApp.xcarchive \
  -exportPath ./build/export \
  -exportOptionsPlist ExportOptions.plist
```

### 4. Upload to TestFlight

```bash
# Using xcrun altool (legacy)
xcrun altool --upload-app \
  --type ios \
  --file ./build/export/MyApp.ipa \
  --apiKey YOUR_API_KEY_ID \
  --apiIssuer YOUR_ISSUER_ID

# Using xcrun notarytool (for macOS)
xcrun notarytool submit MyApp.pkg \
  --key ./AuthKey.p8 \
  --key-id YOUR_API_KEY_ID \
  --issuer YOUR_ISSUER_ID \
  --wait
```

## ExportOptions.plist Templates

### App Store / TestFlight Export
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>method</key>
    <string>app-store</string>
    <key>teamID</key>
    <string>YOUR_TEAM_ID</string>
    <key>uploadSymbols</key>
    <true/>
    <key>signingStyle</key>
    <string>automatic</string>
    <key>destination</key>
    <string>upload</string>
</dict>
</plist>
```

### Development Export
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>method</key>
    <string>development</string>

    <string>YOUR_TEAM_ID</string>
    <key>signingStyle</key>
    <string>automatic</string>
</dict>
</plist>
```

## App Store Connect API

### Authentication (JWT Generation)
```swift
import Foundation
import CryptoKit

func generateJWT(keyID: String, issuerID: String, privateKey: P256.Signing.PrivateKey) -> String {
    let header = ["alg": "ES256", "kid": keyID, "typ": "JWT"]
    let now = Date()
    let payload: [String: Any] = [
        "iss": issuerID,
        "iat": Int(now.timeIntervalSince1970),
        "exp": Int(now.addingTimeInterval(1200).timeIntervalSince1970),
        "aud": "appstoreconnect-v1"
    ]

    // Encode and sign...
    return jwt
}
```

### API Endpoints

```

## Troubleshooting

### Common Issues

| Issue | Cause | Solution |
|-------|-------|----------|
| "No signing certificate" | Missing distribution cert | Install from Apple Developer Portal |
| "Provisioning profile not found" | Profile not installed | Download from Xcode or portal |
| "App Store Connect upload failed" | Invalid credentials | Verify API key and issuer ID |
| "Build processing stuck" | Apple servers | Wait or contact Apple |
| "Export compliance required" | Missing declaration | Add ITSAppUsesNonExemptEncryption to Info.plist |

### Debug Commands
```bash
# Check available signing identities
security find-identity -v -p codesigning

# List provisioning profiles
ls ~/Library/MobileDevice/Provisioning\ Profiles/

# Verify archive
xcodebuild -exportArchive -archivePath MyApp.xcarchive -exportOptionsPlist ExportOptions.plist -exportPath . -allowProvisioningUpdates

# Validate IPA
xcrun altool --validate-app -f MyApp.ipa --apiKey KEY_ID --apiIssuer ISSUER_ID
```

## Best Practices

1. **Automate build numbers** - Use agvtool or CI to auto-increment
2. **Use API keys** - Avoid password-based authentication
3. **Test locally first** - Validate before uploading
4. **Keep certificates secure** - Use CI secrets, not repo
5. **Write good release notes** - Testers need context
6. **Monitor processing** - Builds can fail processing
7. **Use internal testers first** - No review required
8. **Set up notifications** - Know when builds are ready

Build reliably, ship confidently.
