Can't change elements after creation

[Gargo]

For example I need to show "login view controller" and if user input login and password then I need to show "profile view controller. How to do that with this control?
I try to overwrite viewControllers property but it seems your control appends changes instead of replacing
And of course tabBar property is made private which doesn't allow to fix this bug externally. Even if I find it as a subview - each its method is marked private!

Men if you develop a public library for using with cocoapods use private in exception cases only!

example of solution (but i must edit it in this library directly):

internal var viewControllers = [UIViewController]() {
        didSet {
            for v in stackView.subviews {
                v.removeFromSuperview()
            }
            drawTabs()
            guard !viewControllers.isEmpty else { return }
            drawConstraint()
            layoutIfNeeded()
            didSelectTab(index: 0, forceUpdate: true)
        }
    }
