UIKit Drawing Tutorial Fix
I tried the tutorial from raywenderlich.com but the behavior was incorrect. The canvas or UIImageView
seems to move after lifting my finger.

It tried to run the official project from raywenderlich.com but it has the same strange behavior.
Luckily I found a solution, you need to change this line inside touchesEnded
function
// from
UIGraphicsBeginImageContext(mainImageView.frame.size)
// change to
UIGraphicsBeginImageContext(view.frame.size)
And that's it.
