My Objective-C Catalyst app when built with Xcode 16.x/iOS 18 does not have a visible Tab Bar when run on Sequoia. App starts up in first tab, but there is no way to access other tabs. The same app when run on macOS Sonoma (or macOS Catalina) has a normal Tab Bar.

The app has an initial View UITabBarController with 3 tabs. The main tab is a UiSplitViewController. Minimum macOS deployment 10.5.

If app is built on Sonoma with Xcode 15.x/iOS 17 the Tab Bar is normal on macOS Sonoma, Sequoia, and Catalina.

I've tried without success:

  if (@available(macCatalyst 18.0, *)) {
    self.tabBarController.tabBarHidden = false;
  } else {
    // Fallback on earlier versions
  }

I wonder if this console log message has anything to do with the problem:

CLIENT OF UIKIT REQUIRES UPDATE: This process does not adopt UIScene lifecycle. This will become an assert in a future version.
