peripheral(_:didDiscoverServices:)

Tells the delegate that peripheral service discovery succeeded.

Declaration

optional func peripheral(_ peripheral: CBPeripheral, didDiscoverServices error: (any Error)?)

Parameters

  • peripheral:

    The peripheral to which the services belong.

  • error:

    The reason the call failed, or nil if no error occurred.

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.
