UIStackView : Is it really necessary to call both removeFromSuperView and removeArrangedSubview to remove a subview?

Question

From the UIStackView Class Reference

In removeArrangedSubview:

To prevent the view from appearing on screen after calling the stack’s removeArrang

Answer 1

For removing i use this extension. Don't really know is it necessary to remove constraints. But maybe it would help.

extension UIStackView {
    func removeAllArrangedSubviews() {
        let removedSubviews = arrangedSubviews.reduce([]) { (allSubviews, subview) -> [UIView] in
            self.removeArrangedSubview(subview)
            return allSubviews + [subview]
        }

        for v in removedSubviews {
            if v.superview != nil {
                NSLayoutConstraint.deactivate(v.constraints)
                v.removeFromSuperview()
            }
        }
    }
}
