UIView viewwithtag method in swift

You need to use a typecast. This code will do it:

    if let theLabel = self.view.viewWithTag(123) as? UILabel {
        theLabel.text = "some text"
    }

You need to write as

var getMyLabel : UILabel = self.view.viewWithTag(tagValue) as UILabel;

viewWithTag: returns a UIView, you need to typecast it to UILabel.

var yourLabel : UILabel = yourView.viewWithTag(yourTag) as! UILabel;
