AVMutableCompositionTrack
A mutable track in a composition that you use to insert, remove, and scale track segments without affecting their low-level representation.
Declaration
class AVMutableCompositionTrackOverview
Use this object to define constraints for the temporal arrangement of the track segments. If you set the composition’s track segments, you can test whether they meet the constraints by calling the validateSegments(_:) method.
