Crash: Fatal Exception: NSGenericException #367

Closed ravindrashetty closed 4 years ago

ravindrashetty commented 4 years ago

Seeing this crash on recent releases. Details Below.

Crash Description:

Unable to activate constraint with anchors <NSLayoutYAxisAnchor:0x1049d7540 "SwiftMessages.MaskingView:0x10cd1ffe0.bottom"> and <NSLayoutYAxisAnchor:0x1049d2bf0 "UITabBar:0x10a4e3a00.top"> because they have no common ancestor. Does the constraint or its anchors reference items in different view hierarchies? That's illegal.

Stack trace:

This is a duplicate of #348.

So far nobody has provided reproduction steps, so I there's not much I can do. If you can help me reproduce, I'll take a look.
