It's known UIStackView bug (http://www.openradar.me/25087688). There is a thread on SO about it: (Swift: Disappearing views from a stackView). Long story short:

The bug is that hiding and showing views in a stack view is cumulative. Weird Apple bug. If you hide a view in a stack view twice, you need to show it twice to get it back.

To fix this issue you can use following extension:

extension UIView {
    var isHiddenInStackView: Bool {
        get {
            return isHidden
        }
        set {
            if isHidden != newValue {
                isHidden = newValue
            }
        }
    }
}
