In my ios app with new Xcode 11 GM Seed 2 after deploy, apple returned error:
ITMS-90683: Missing Purpose String in Info.plist with NSBluetoothAlwaysUsageDe
If your app has a deployment target earlier than iOS 13, add the NSBluetoothPeripheralUsageDescription key to your app’s Information Property List file in addition to NSBluetoothAlwaysUsageDescription key as one or more of third party in your project uses bluetooth functionality.
