thanks for the reply. I just coded according to sample code provided by apple. And I also need to get the NSPersistentStoreDescription instance to config the deduplicate logic. The weird thing is, I’m pretty sure the code worked on earlier OS versions, but it throws Error after upgrading to macOS 17.5 and iOS 17.5.

thanks, that's really wierd. but in my situation, this doesn't work, because the innerValue is invisble to menu or outside component.
