Unfortunately, this isn't true for me. It just happened on devices that went from iOS 16.6.1 -> 17.0 RC & watchOS 9.6.2 -> 10.0 RC.

Thanks for getting this fixed! I will say that this has happened quite a few times now, and some of those times took weeks to fix (or were fixed simply by waiting for a new build) and I couldn't debug on-device. It would be wonderful if there was an improvement to the iOS/watchOS build deployment process such that symbol uploads are verified at deployment time.

While this trick works sometimes, unfortunately, it doesn't for this build (at least for my device). Xcode tries to use the duplicated symbols, but when performing an install action on-device, it fails and then tries to download the symbols fresh. Edit: Scratch that, after a macOS restart, builds are now installing properly.
