Swift extend UIView to return calling type

Asked By: Anonymous

I want to extend base class (UIView) where I work on that object and return the calling object with correct type

extension UIView {
    func withCleanBg() -> UIView {
        self.backgroundColor = .clear
        return self;

For example if I call let btn:UIButton = UIButton().withCleanBg() I want the btn to stay UIButton after calling the extension and not to get UpCasted.

I want this to chain function calls like
UIButton().withCleanBg().withFillInParent() and so on

Return Self as the type:

func withCleanBg() -> Self {
