Create a copy of a UIView in Swift

by

You can make an UIView extension. In example snippet below, function copyView returns an AnyObject so you could copy any subclass of an UIView, ie UIImageView. If you want to copy only UIView you can change the return type to UIView. 

//MARK: - UIView Extensions

extension UIView
{
    func copyView<T: UIView>() -> T {
        return NSKeyedUnarchiver.unarchiveObject(with: NSKeyedArchiver.archivedData(withRootObject: self)) as! T
    }
}

Example usage:

let sourceView = UIView()
let copiedView: UIView = sourceView.copyView()
