I’m facing a similar issue with arm64e on macOS. When I turn on the Authenticate Pointers feature for my macOS app target on Xcode 26, the app target prompts requiring the 'arm64e-apple-macos’ target, the same warning message as the original poster, for local swift packages using in the main target and the target is no longer able to build. @WangZiYuan If you received any personal response from Feedback Assistant, could you please share it? @DTS Engineer Is there any way to detour it? Should I create a new post in this forumn/feedback? My environment is: macOS: Version 26.1 Beta (25B5042k) Xcode: Version 26.1 beta (17B5025f)

After my post, I found NSPopUpButton (or NSButton) has a private API named semanticContext for this purpose. Though, I can’t use it since my app is distributed in the App Store... cf. https://stackoverflow.com/questions/79593493/how-to-achieve-grouped-form-styled-controls-using-appkit/79607626#79607626

If this is the case, I'd like to see the feature in SwiftUI in future SDK. So I sent a feature request: FB18743468.

Sent feedback: FB18401945.

Hi there, I’ve also been receiving crash reports to my app that seem to point to the same cause as yours. NSOutlineView on macOS 15 crashes in NSConcreteMapTable, [_TtCs12_SwiftObject isEqual:] (and isSubclass in my cases). I've also sent Feedback with my case FB16913684. FB16913684: NSOutlineView crashes by checking isSubclass internally on macOS 15
