livePhotoMovieFileURL
A URL at which to write Live Photo movie output.
Declaration
var livePhotoMovieFileURL: URL? { get set }Discussion
Live Photos capture both a still image and a short movie, which the system presents together in user interfaces such as the Photos app. By default, this property’s value is nil, disabling Live Photo capture. Set this property to a file URL to capture Live Photos.
When you enable Live Photo capture, the following requirements apply:
The photo output’s isLivePhotoCaptureEnabled property must be true, and its and isLivePhotoCaptureSuspended property must be false.
The URL you specify must be a file URL to an accessible location in your app’s sandbox.
Your delegate object must implement the photoOutput(_:didFinishProcessingLivePhotoToMovieFileAt:duration:photoDisplayTime:resolvedSettings:error:) method.
The capture output validates these requirements when you call the capturePhoto(with:delegate:) method. If your settings and delegate don’t meet these requirements, that method raises an exception.
