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.

Answer 1

Use @IBDesignable and @IBInspectable to do the same.

They are re-useable, easily modifiable from the Interface Builder and the changes are reflected immediately in the Storyboard

Conform the objects in the storyboard to the particular class

Code Snippet:

@IBDesignable
class CustomView: UIView{

@IBInspectable var borderWidth: CGFloat = 0.0{

    didSet{

        self.layer.borderWidth = borderWidth
    }
}


@IBInspectable var borderColor: UIColor = UIColor.clear {

    didSet {

        self.layer.borderColor = borderColor.cgColor
    }
}

override func prepareForInterfaceBuilder() {

    super.prepareForInterfaceBuilder()
}

}

Allows easy modification from Interface Builder:
