In Swift, how do I get the width (or height) at runtime, of a UIView that\'s created programmatically using auto layout constraints?

I\'ve tried view1.frame.size.

    Just one thing about these fields:

    self.view1.frame.size.width
    self.view1.frame.size.height
    

    Are only actual user device size if the view has been drawn to screen, else they are what ever you set them as in the storyboard. So if your trying to perform some kind of calculation before the view is drawn you will have to figure out the width or height another way!
