Discussion
Core Bluetooth invokes this method when your app calls the discoverServices(_:) method. If the peripheral successfully discovers services, you can access them through the peripheral’s services property. If successful, the error parameter is nil. If unsuccessful, the error parameter returns the cause of the failure.
