Tab Bar missing for macCatalyst app on macOS 26.2 Beta 3

This is a problem from Beta 1, but since there is no fix yet in Beta 3, I'd like to raise it.

The app is built with macCatalyst, and we have pretty simple tab bar controller setup:

viewController = UITabBarController()
viewController.tabBar.tintColor = .buttonForegroundColor

importWorkflow = ModelImportWorkflow(
  userInterfaceIdiom: userInterfaceIdiom, workspace: workspace)
mergeWorkflow = ModelMergeWorkflow(userInterfaceIdiom: userInterfaceIdiom, workspace: workspace)
listWorkflow = ModelListWorkflow(workspace: workspace, userInterfaceIdiom: userInterfaceIdiom)
viewController.viewControllers = [
  listWorkflow.viewControllable, importWorkflow.viewControllable,
  mergeWorkflow.viewControllable,
]
viewController.modalPresentationStyle = .formSheet

We don't do any customizations on the tab bar and in Beta 3 (26.2), there is no way to found the tab bar (attached a user reported image).

Please advise what's the course of action. Thanks.

This sounds like a possible framework issue. Can you file a feedback through Feedback Assistant and attach a sample project that reproduces the issue? Once you do, reply with the Feedback ID.

Attached a sample project to FB21106079, when you build for simulator, it will show the tab correctly. When you build for macCatalyst, there is not tab.
