Class does not conform to 'CBPeripheralManagerDelegate' in Swift

I'm trying to build iBeacon emitter in Swift and I cannot get my class to adopt the CBPeripheralManagerDelegate protocol.

This protocol is required in Objective-C for initializing the PeripheralManager object, but in Swift, I will get the following error:

class MyBeacon: CBPeripheralManagerDelegate {
    // ...
}

gives error:

'MyBeacon' does not conform to 'CBPeripheralManagerDelegate'

Since my class is not adopting the protocol, I also get an error when I try to initialize the PeripheralManager using auto complete

self.peripheralManager = CBPeripheralManager(delegate: self, queue: queue)

gives error:

Could not find an overload for 'init' that accepts the supplied arguments

Can anyone please shed some light?

Solution

  • You have to implement this method as this method not optional and must be implemented if you confirming CBPeripheralManagerDelegate

    func peripheralManagerDidUpdateState(_ peripheral: CBPeripheralManager) {

}

    write this in class error will go off

    refer docs

    The delegate of a CBPeripheralManager object must adopt the CBPeripheralManagerDelegate protocol, a protocol consisting of numerous optional methods and one required method.The protocol’s required method, which indicates whether the peripheral manager is available, is called when the peripheral manager’s state is updated.
