Is it possible to reorder collection view cells similar to the way the home screen works on the Apple TV?The APIs appear to be all there, but I tried a bunch of stuff (setting installsStandardGestureForInteractiveMovement to true, returning true from canMoveItemAtIndexPath, implementing moveItemAtIndexPath, setting editing to true) in the UIKitCatalog sample and didn't observe any difference. Perhaps I don't know what the "standard gesture" is, or some other delegate methods need to be implemented as well, or maybe it just doesn't work on tvOS. Does anyone know if this is possible and if so, how to make it happen?
