It seems you are asking about Lottie animations in the system tab bar. The tab bar (TabView in SwiftUI / UITabBarController in UIKit) supports SF Symbols and animated symbol effects such as .bounce, .wiggle, .breathe etc.. The tab bar does not natively support Lottie animations. For more information, see What's new in SF Symbols 7  Travis

Here is more concrete context. Platform / tools Target: macOS app Language / frameworks: Swift, SwiftUI, SwiftData Cloud sync: SwiftData with CloudKit mirroring in the production configuration Xcode: 26.4 (17E192) Test OS: macOS 26.4 (25E246) What I’m seeing In the macOS app, issue board scrolling can become inconsistent or very slow. Changing an issue status from detail view can be very slow. Scrolling the status menu itself can be slow. Typing in issue description/notes fields can become sluggish. The problem is much more noticeable with my full production-sized dataset than with a small dev dataset. What I’ve tested so far I compared a small dev dataset vs a much larger production-sized dataset. With a small dataset, the same UI feels fast and smooth. With the large dataset, the same UI becomes noticeably slower. I also tested a local-only copy of the production dataset with CloudKit disabled. That improved some behavior, but it did not remove the lag entirely. When I reduced the local test datase

I tried to open my project with Xcode 26.5 beta 1 and to view the Preview of some SwiftUI views present in local Packages referenced by the project, and they worked as expected, without any issue. I also tried with the very simple test project, and the result is the same. I can say that this Xcode 26.5 beta 1 behaves like Xcode 25.3. Thank you for this message.

How are you setting the title? I tried to reproduce, but getting a different behaviour. import SwiftUI struct ContentView: View { var body: some View { NavigationStack { Text(View) .navigationTitle(BYRON'S GRILLED CHEESE EMPORIUM) .navigationBarTitleDisplayMode(.inline) .toolbar { ToolbarItem(placement: .topBarTrailing) { Text(Cancel Order) } } } } } Which looks like this: And if I remove the .navigationTitle it looks like this:

I am having the same issue on both of my machines (both running Xcode 26.4 and 26.4 simulators.) After setting the simulator back to iOS 26.2, I can work in the SwiftUI canvas.

Thank you for filing the feedback, @newwbee. We responded to your feedback privately a while ago, but I want to include the response here, too, for anyone else that might have the same question and stumbles upon this. SwiftUI’s Settings scene is designed to help you build a first-class Mac settings experience that follows Apple’s Human Interface Guidelines at https://developer.apple.com/design/human-interface-guidelines/settings#macOS Toolbars within Settings scenes use a style appropriate for a typical macOS settings window, which displays centered tabs to group related settings. (Please refer to Settings windows in apps like Safari and Mail as an example.) People also typically expect macOS application settings to be applied as soon as the setting is changed, without the need for a “Save” button. To create a bespoke settings experience for your app, you can use a regular Window scene, which uses a default toolbar style that you’d be familiar with in an application’s main and document windows.

Try taking to social media and “hash tagging” with popular SwiftUI or other App Development related tags. That seems to get traction faster than using official channels.
