## Discussion

During initial detection execution, [`cameraLensSmudgeDetectionStatus`](/documentation/AVFoundation/AVCaptureDevice/cameraLensSmudgeDetectionStatus) returns `AVCaptureCameraLensSmudgeDetectionStatusUnknown` until the detection result settles. Once a detection result is produced, [`cameraLensSmudgeDetectionStatus`](/documentation/AVFoundation/AVCaptureDevice/cameraLensSmudgeDetectionStatus) returns the most recent detection result. This property can be key-value observed.
