white or light ASAuthorizationAppleIDButton "Sign in with Apple" button - Swift

Question

I am implementing ASAuthorizationAppleIDButton - as per Apple's request - but unfortunately my login background is dark and I can't find how to change the button color to a light or white button like the ones Apple show in many of their examples?

This is what I have:

let appleButton = ASAuthorizationAppleIDButton()

override func viewDidLoad() {
    super.viewDidLoad()       
    setAppleButtonStyle()
}

func setAppleButtonStyle() {
    if #available(iOS 13.0, *) {
        appleButton.translatesAutoresizingMaskIntoConstraints = false

        view.addSubview(appleButton)
        NSLayoutConstraint.activate([
            appleButton.centerYAnchor.constraint(equalTo: facebookLoginView.centerYAnchor, constant: -70),
            appleButton.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 16),
            appleButton.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -16),
            appleButton.heightAnchor.constraint(equalToConstant: 50)
        ])
    } else {
        //Do Nothing
    }

}

Answer 1

Simply provide the desired style when you instantiate the button instance.

E.g.

let appleButton = ASAuthorizationAppleIDButton(type: .default, style: .white)

Answer 2

This would be what you would use if you were using Objective-C:

 ASAuthorizationAppleIDButton *appleIDButton = [ASAuthorizationAppleIDButton buttonWithType:ASAuthorizationAppleIDButtonTypeContinue style:ASAuthorizationAppleIDButtonStyleBlack];
