NSBluetoothAlwaysUsageDescription
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 NSBluetoothPeripheraUsageDescription,
while devices running later versions rely on NSBluetoothAlwaysUsageDescription.
