Set to tuples to avoid code repetition

Avoid code repetition in constructors by setting a tuple of variables with a one liner:

class Contact: UIView
{
    private var message: UILabel
    private var phone: UITextView
    
    required init?(coder aDecoder: NSCoder) {
        (message, phone) = self.dynamicType.setUp()
        super.init(coder: aDecoder)
    }
    
    override func awakeFromNib() {
        (message, phone) = self.dynamicType.setUp()
        super.awakeFromNib()
    }
    
    override init(frame: CGRect) {
        (message, phone) = self.dynamicType.setUp()
        super.init(frame: frame)
    }
    
    private static func setUp(){
        let message = UILabel()  // ...
        let phone = UITextView() // ...
        return (message, phone)
    }
}
