How to do it...

With Xcode open, let's get started:

1. Create a new project in Xcode. Go to File | New | Project | iOS App.
2. In Main.storyboard, add the following:
   1. Add UISegmentedControl with two options (Photo / Camera Roll and Live Camera).
   2. Next, add a UILabel view just underneath. 
   3. Add a UIImageView view beneath that.
   4. Finally, add a UIButton component.
3. Space these accordingly using AutoLayout constraints with UIImageView being the prominent object:

4. Once we have this in place, let's hook these up to our ViewController.swift file:

@IBOutlet weak var imageView: UIImageView!
@IBOutlet weak var labelView: UILabel!
@IBAction func onSelectPhoto(_ sender: Any)

Take note that in the preceding, we have two IBOutlet and one IBAction (we don't need an outlet for UIButton, we just care about its action).

5. Next, populate IBAction with the following code:
