I accidentally replied in the main thread, so I'm attaching the same message here: I reproduce the bug in a small test project. The reproduction is attached to the Feedback Assistant Report FB25261013 (in that thread I added a fixed minimal reproduction example with the workaround line commented out). I also uploaded the reproduction to GitHub, please see here. Thank you for your help.

Thanks for the reply. By mistake I left tabBarController.view.frame = view.bounds line uncommented in the reproduction example. I tried running it with the line commented out using Xcode 27.2 RC and unfortunately I still reproduce the bug.

Thank you for your reply. I added a link to this thread in the Feedback Assistant report.
