The issue is finally solved with Xcode 13.0 beta 3 - you can attach the statusBarHidden modifier to both a TabView and a NavigationView and the status bar hides as expected.

Thanks everyone, I was doubting my sanity... Just tried it out in the iPhone 13 simulator (not the mini), I can confirmed the issue does not appear.

Same result on my end. None of the solutions worked for me. I have filed a ticket through Apple's Feedback assistant with detailed description of the problem. I have also added the link to this thread.

thanks for your reply. The feedback IDs are FB13284132 and FB13473137.
