Tinder like pan iOS

Answer 1

You can create custom class of card with own gesture recognizer and create delegate with methods didSwipeLeft/Right. Delegate will get call back on swiping and move next card to the front. For code reusing you can create universal manager for this cards. You can look at the implementation of card and manager here: https://github.com/Yalantis/Koloda
