Hey All, I'm interested in creating a interactive transition much like the 'pinch to view/dismiss' transition of the photos app or Instagram, but I'm unsure what feature of UIKi are most helpful for me. Also, I've seen more and more apps presenting modal content in a card that the user can 'swipe down to dismiss'. I'm also investigating that. Could anyone point me in the direction of some UiKit framework components that apply here? I recall that interactive transitions and animations were part of some previous iOS releases, but I don't recall the component names to search more specifically. Thank you!
