Apple has a Section called "Handling Multi-Touch Events" here: https://developer.apple.com/library/content/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/multitouch_background/multitouch_background.html
It is the official Apple guide on how you can handle almost all of your touch events with the standard controls and gesture recognizers in UIKit.
