Discussion

Before changing the value of this property, you must call lockForConfiguration() to acquire exclusive access to the device’s configuration properties. Otherwise, setting the value of this property raises an exception. When you finish configuring the device, call unlockForConfiguration() to release the lock and allow other devices to configure the settings.

You can observe changes to the value of this property using Key-value observing.

See AVCaptureDevice.FocusMode for possible values.
