hello friends, this is how we can create a UIButton and UILabel in swift.

Set a UILabel in swift

        var label = UILabel(frame: CGRectMake(100, 100, self.view.bounds.size.width, 50))
        label.center = self.view.center
        label.textAlignment = NSTextAlignment.Center
        label.text = test label
        label.textColor = UIColor.grayColor()
        self.view.addSubview(label)

Set a UIButton in swift

let testButton = UIButton.buttonWithType(UIButtonType.System) as! UIButton
        testButton.backgroundColor = UIColor.orangeColor()
        testButton .setTitleColor(UIColor.whiteColor(), forState: UIControlState.Normal)
        testButton.setTitle(click here, forState: UIControlState.Normal)
        testButton.frame = CGRectMake(self.view.bounds.size.width,100, 100, 50)
        testButton.addTarget(self, action: "buttonClicked:, forControlEvents: UIControlEvents.TouchUpInside)

        self.view.addSubview(testButton)
