A Boolean value indicating whether the animator is interruptible and can be paused or stopped.
Mac Catalyst 13.0+
When the value of this property is YES, you can use the pauseAnimation and stopAnimation: methods to interrupt the animations and make changes. When the value of this property is NO, the animations run to completion (and without interruption) after you call the startAnimation method. If you use a view property animator object to implement an interruptible view controller transition, this property must be YES.
