How should I achieve this

Answer 1

using Extension:

extension UIButton
{
 func setUpLayer(sampleButton: UIButton?) {
  sampleButton!.setTitle("GET STARTED", forState: UIControlState.Normal)
  sampleButton?.tintColor =  UIColor.whiteColor()
  sampleButton!.frame = CGRect(x:50, y:500, width:170, height:40)
  sampleButton!.layer.borderWidth = 1.0
  sampleButton!.layer.borderColor = UIColor.whiteColor().colorWithAlphaComponent(0.5).CGColor
  sampleButton!.layer.cornerRadius = 5.0

  sampleButton!.layer.shadowRadius =  3.0
  sampleButton!.layer.shadowColor =  UIColor.whiteColor().CGColor
  sampleButton!.layer.shadowOpacity =  0.3
 }

}

Usage:

  let sampleUIButton =  UIButton()
  sampleUIButton.setUpLayer(sampleUIButton)
  self.view.addSubview(sampleUIButton)
