I have a Catalyst-enabled app with a UITabBarController for view switching and a custom "tab bar" (actually a UICollectionView). In my case, I wanted to hide this new tab bar and side bar. Here is the workaround I needed to do to accomplish that, as setTabBarHidden didn't work for me. Posting here in case it helps anyone else. internal class MainTabBarController: UITabBarController { internal override func viewDidLoad() { #if targetEnvironment(macCatalyst) mode = .tabSidebar sidebar.isHidden = true #else setTabBarHidden(true, animated: false) #endif } }

I actually figured it out - it appears that it isn't just included in UIKit, but is instead part of an extension in HealthKitUI. Fixed by adding import HealthKitUI

I also need this functionality and have requested it in FB19932104

It's there now.

I've submitted this as FB21030260. To give a little more detail here for others: my Anchored Object Query used to update step count every 10 seconds or so. Now it only appears to update every 4 to 5 minutes. I initially thought I had broken the query entirely, but it DOES eventually get a step count value - just at a glacial pace.

I'm curious what the intended behavior is here? Is swipe navigation meant to be suppressed if the back button is hidden? I have a scenario where I'm trying to use a custom-drawn navigation bar, but actually WANT the swipe action to still work. Is that possible (outside of using a .zoom transition - which may, or may not, be a bug). Edit: Found this work around for what I want - extension UINavigationController: @retroactive UIGestureRecognizerDelegate { override open func viewDidLoad() { super.viewDidLoad() interactivePopGestureRecognizer?.delegate = self } public func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool { // Override this to cause the navigation controller to do the back swipe even if the navigation bar is hidden return viewControllers.count > 1 } }
