How to create action for UIButton and conner Radius in swift 5

Question

create login button( set title and conner Radius on UI button)

 lazy var loginButton: UIButton = {
    let button = UIButton()
    button.setTitle("Log In", for: .normal)
    button.layer.cornerRadius = 15
    button.backgroundColor = UIColor.red
 
    
    return button
}()

Answer 1

The modern way is to add the action as a UIAction.

lazy var test: UIButton = {
    let test = UIButton()
    test.translatesAutoresizingMaskIntoConstraints = false
    test.setTitle("See More Answers", for: .normal)
    test.setTitleColor(.systemBlue, for: .normal)
    let action = UIAction { action in
        print("howdy!")
    }
    test.addAction(action, for: .touchUpInside)
    return test
}()

Nicer syntax can be achieved through an extension, as I demonstrate here.
