iOS dynamic UI in simple terms?

This may be too basic or require rephrasing. I am in the process of learning Swift and iOS programming and have developed a basic application that runs successfully on my iPhone 5. The app consists of a label, a button, and a UIImageView. It looks the way I want it to on my iPhone 5.

I figured most of this out by just playing around and so I am creating all these elements programatically. The code looks like this:

let banner = UILabel(frame: CGRect(x: 10, y: 10, width: 300.0, height: 75.0))
let button = UIButton(frame: CGRect(x: 45, y: 75, width: 235.0, height: 60.0))
let imageView = UIImageView(frame: CGRect(x: 22, y: 150, width: 280.0, height: 410.0))

And then I configure them in viewDidLoad to make them show stuff.

Now the question...how to I make them all the right size when running on different devices? I can load up the app on my iPad Mini but it's all scrunched over to the left of the view. So I need to do some kind of dynamic layout but not sure where to start.

All help appreciated!

Rather than creating the view sizes explicitly with initWithFrame: constructors, you can programmatically create and NSLayoutConstraints to your views to automatically layout your views, the same as if you used Auto Layout with the Interface Builder. See Apple's Auto Layout Guide for more details.
