How to set the custom border color of UIView programmatically?

Question

I am trying to set the custom border color of UIView programmatically in Swift.

You can write an extension to use it with all the UIViews eg. UIButton, UILabel, UIImageView etc. You can customise my following method as per your requirement, but I think it will work well for you.

extension UIView{

    func setBorder(radius:CGFloat, color:UIColor = UIColor.clearColor()) -> UIView{
        var roundView:UIView = self
        roundView.layer.cornerRadius = CGFloat(radius)
        roundView.layer.borderWidth = 1
        roundView.layer.borderColor = color.CGColor
        roundView.clipsToBounds = true
        return roundView
    }
}

Usage:

btnLogin.setBorder(7, color: UIColor.lightGrayColor())
imgViewUserPick.setBorder(10)
