## Discussion

Check this property in your implementation of the delegate methods [`centralManagerDidUpdateState(_:)`](/documentation/CoreBluetooth/CBCentralManagerDelegate/centralManagerDidUpdateState(_:)) and [`peripheralManagerDidUpdateState(_:)`](/documentation/CoreBluetooth/CBPeripheralManagerDelegate/peripheralManagerDidUpdateState(_:)) to determine whether your app can use Core Bluetooth. You can also use it to check the app’s authorization status before creating a [`CBManager`](/documentation/CoreBluetooth/CBManager) instance.

The initial value of this property is [`CBManagerAuthorization.notDetermined`](/documentation/CoreBluetooth/CBManagerAuthorization/notDetermined).
