[SOLVED] beaconManager(_ , didRangeBeacons, inRegion) never called?

I can’t detect beacons in my app. (Previously it was working)

In my ViewController (ESTBeaconManagerDelegate)

func beaconManager(_ manager: Any!, didRangeBeacons beacons: [AnyObject]!, inRegion region: CLBeaconRegion!) {
    // codes here has never called
}

I also tried

@nonobjc
    func beaconManager(_ manager: Any!, didRangeBeacons beacons: [AnyObject]!, inRegion region: CLBeaconRegion!) {
    // codes here has never called
}

Development logs:

You can also see my git logs here.

I’m not sure why the code which has been operating is no longer does not work.
Anything has been changed in the past year?
I’m happy if you share me any ideas.

Sorry, I found the label has been changed (not ‘inRegion’ but ‘in’).
