How to use addTarget method in swift 3

Question

here is my button object

    let loginRegisterButton:UIButton = {
    let button = UIButton(type: .system)
    button.backgroundColor = UIColor         


        

Answer 1

Instead of

let loginRegisterButton:UIButton = {
//...  }()

Try:

lazy var loginRegisterButton:UIButton = {
//...  }()

That should fix the compile error!!!
