View being blocked by UITransitionView after being presented

Answer 1

I had a similar issue where a UITransitionView kept blocking my views, preventing any user interaction.

In my case this was due to an uncompleted custom animated UIViewController transition.

I forgot to properly complete my transition with:

TransitionContext.completeTransition(transitionContext.transitionWasCancelled)

or

TransitionContext.completeTransition(!transitionContext.transitionWasCancelled)

In the

func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {}

from the UIViewControllerAnimatedTransitioning protocol
