I’m running into a problem with SwiftUI/AppKit event handling on macOS Tahoe 26.2.
I have a layered view setup:
-
Bottom: AppKit NSView (NSViewRepresentable)
-
Middle: SwiftUI view in an NSHostingView with drag/tap gestures
-
Top: Another SwiftUI view in an NSHostingView
On macOS 26.2, the middle NSHostingView no longer receives mouse or drag events when the top NSHostingView is present. Events pass through to the AppKit view below. Removing the top layer immediately restores interaction. Everything works correctly on macOS Sequoia.
I’ve posted a full reproducible example and detailed explanation on Stack Overflow, including a single-file demo:

I also found a related older discussion here, but couldn’t get the suggested workaround to apply: https://developer.apple.com/forums/thread/759081
Any guidance would be appreciated.
Thanks!
