Running the iOS demo

If you are running the iOS app locally, provide your Apple Team ID in an ExternalDeveloper.xcconfig file so local signing settings stay out of git:

1. Run cp Configuration/ExternalDeveloper.xcconfig.example Configuration/ExternalDeveloper.xcconfig
2. Edit Configuration/ExternalDeveloper.xcconfig and set TEAM_ID=YOUR_APPLE_TEAM_ID
3. Clean and rebuild the iOS app in Xcode
