    Use withAlphaComponent:

    profileView.layer.borderColor = UIColor.white.withAlphaComponent(0.5).cgColor

    or:

    profileView.layer.borderColor = UIColor.white.cgColor.copy(alpha: 0.5)

    Obviously you can choose whatever alpha value you want in the range 0.0 to 1.0.

    Or in this case you can use:

    profileView.layer.borderColor = UIColor(white: 1.0, alpha: 0.5).cgColor
