Set UIViewController view property to custom UIView class without storyboard / nib

Question

I have a UIViewController called LoginViewController. I want to build the view of that LoginViewController fully programmatically<

Answer 1

In your Viewcontroller's loadView method do this:

class LoginViewController: UIViewController {
    override func loadView() {
        super.view = LoginView()
    }
}

In your UIView's custom class do this:

class LoginView: UIView {
    convenience init() {
        self.init(frame: UIScreen.main.bounds)
        setupLabels()
    }
}

Now your UIView has a frame , and you can setup all your views through code by providing them frames.
