Working through the iBeacon tutorial Part 2: Background monitoring. I’m stuck with an error at step, “Show an “enter” notification”:
In the AppDelegate, add the following implementation of the didEnterRegion delegate method […]
This produces the following Warning: Non-@objc method 'beaconManager(_:didEnterRegion:)' cannot satisfy optional requirement of @objc protocol 'ESTBeaconManagerDelegate'
If you share you code I can take a look. It looks like one of the protocols (an optional one) has not been defined in the delegate. the delegate method looks like it’s defined with an @Optional attribute so it’s not required to implement. That’s why everything compiles but gives a warning.
