let gradient = CAGradientLayer()
gradient.frame =  CGRect(origin: CGPointZero, size: self.myButton.frame.size)
gradient.colors = [UIColor.blueColor().CGColor, UIColor.greenColor().CGColor]

let shape = CAShapeLayer()
shape.lineWidth = 2
shape.path = UIBezierPath(rect: self.myButton.bounds).CGPath
shape.strokeColor = UIColor.blackColor().CGColor
shape.fillColor = UIColor.clearColor().CGColor
gradient.mask = shape

self.myButton.layer.addSublayer(gradient)

Swift 3 version:

    let gradient = CAGradientLayer()
    gradient.frame =  CGRect(origin: CGPoint.zero, size: self.myButton.frame.size)
    gradient.colors = [UIColor.blue.cgColor, UIColor.green.cgColor]
    
    let shape = CAShapeLayer()
    shape.lineWidth = 2
    shape.path = UIBezierPath(rect: self.myButton.bounds).cgPath
    shape.strokeColor = UIColor.black.cgColor
    shape.fillColor = UIColor.clear.cgColor
    gradient.mask = shape
    
    self.myButton.layer.addSublayer(gradient)
