IBOutlet properties nil after custom view loaded from xib

Question

Something strange going on with IBOutlets.

In code I've try to access to this properties, but they are nil. Code:

class CustomKeyboard: UIView {      @IBOutlet var aButt: UIButton!     @IBOutlet var oButt: UIButton!      class func keyboard() -> UIView {         let nib = UINib(nibName: "CustomKeyboard", bundle: nil)         return nib.instantiateWithOwner(self, options: nil).first as UIView     }      override init() {         super.init()         commonInit()     }      override init(frame: CGRect) {         super.init(frame: frame)         commonInit()     }      required init(coder aDecoder: NSCoder) {         super.init(coder: aDecoder)         commonInit()     }      // MARK: - Private     private func commonInit() {         println(aButt)         // aButt is nil          aButt = self.viewWithTag(1) as UIButton         println(aButt)         // aButt is not nil     } }

That's expected, because the IBOutlet(s) are not assigned by the time the initializer is called. You don't need the commonInit, just an override of awakeFromNib as follows:

override func awakeFromNib() {     super.awakeFromNib()      print(aButt) }
