Surprisingly, found a solution here: https://forums.developer.apple.com/forums/thread/711360 Adding the following in makeUIViewController() solved the issue. @DTS Engineer @fandrade controller.beginAppearanceTransition(true, animated: false)

@DTS Engineer @fandrade Is there a bug raised/fixed already? Experiencing the same issue in TabView.

Even after doing as suggested by Frameworks Engineer the height returned is zero.
