I made some changes to [Dan's answer][1] so that I could add borders to multiple edges with one command:
infoView.addBorder(toEdges: [.left, .bottom, .right], color: borderColor, thickness: 1)
Here's the full code:
extension UIView {
func addBorder(toEdges edges: UIRectEdge, color: UIColor, thickness: CGFloat) {
func addBorder(toEdge edges: UIRectEdge, color: UIColor, thickness: CGFloat) {
let border = CALayer()
border.backgroundColor = color.cgColor
switch edges {
case .top:
border.frame = CGRect(x: 0, y: 0, width: frame.width, height: thickness)
case .bottom:
border.frame = CGRect(x: 0, y: frame.height - thickness, width: frame.width, height: thickness)
case .left:
border.frame = CGRect(x: 0, y: 0, width: thickness, height: frame.height)
case .right:
border.frame = CGRect(x: frame.width - thickness, y: 0, width: thickness, height: frame.height)
default:
break
}
layer.addSublayer(border)
}
if edges.contains(.top) || edges.contains(.all) {
addBorder(toEdge: .top, color: color, thickness: thickness)
}
if edges.contains(.bottom) || edges.contains(.all) {
addBorder(toEdge: .bottom, color: color, thickness: thickness)
}
if edges.contains(.left) || edges.contains(.all) {
addBorder(toEdge: .left, color: color, thickness: thickness)
}
if edges.contains(.right) || edges.contains(.all) {
addBorder(toEdge: .right, color: color, thickness: thickness)
}
}
}

}
}
