A message that tells people why the app is requesting the ability to connect to Bluetooth peripherals.
Discussion
For apps with a deployment target of iOS 13 and later, use NSBluetoothAlwaysUsageDescription instead.
For deployment targets earlier than iOS 13, add both NSBluetoothAlwaysUsageDescription and NSBluetoothPeripheralUsageDescription to your app’s Information Property List file. Devices running earlier versions of iOS rely on NSBluetoothPeripheralUsageDescription, while devices running later versions rely on NSBluetoothAlwaysUsageDescription.
