addTraget to UIButton in UIView. getting error “terminating with uncaught exception of type NSException”
I have a UIView class and inside it I have a UIButton and when clicked it supposed to open a UIViewController class. However every time I click it I get an error in AppDelegate - Thread 1: signal SIGABRT. terminal: terminating with uncaught exception of type NSException.
lazy var signupButton: UIButton = {
let button = UIButton(type: .system)
button.setTitle("Sign me up", for: .normal)
button.setTitleColor(UIColor.blue, for: .normal)
button.backgroundColor = UIColor.white
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 17)
button.translatesAutoresizingMaskIntoConstraints = false
button.addTarget(self, action: #selector(handleLogin(vc:)), for: .touchUpInside)
return button
}()
@objc func handleLogin(vc: UIViewController) {
let loginController = LoginController()
vc.present(loginController, animated: true, completion: nil)
}

The problem is with the parameter to func handleLogin. You have it set up to expect an instance of a UIViewController but it will actually be the sender of the selector, which will be a UIButton in this case.
You need to update it to the following:
@objc func handleLogin(sender: UIButton) {
let loginController = LoginController()
present(loginController, animated: true, completion: nil)
}
You could alternately do this since you don't need the sender parameter at all.
button.addTarget(self, action: #selector(handleLogin), for: .touchUpInside)
return button
@objc func handleLogin() {
let loginController = LoginController()
present(loginController, animated: true, completion: nil)
}
