Hi, thank you for your reply. I have checked and confirmed that all AppleUser entity fields (id, name, email, password, createdAt) are optional, relationships (posts, comments) are optional, and I assign values when creating a new object, but Core Data still throws a nilError during registration; I have uploaded my project to GitHub for your reference here: https://github.com/Kawiichao/job. If reviewing it requires any payment, please let me know in advance. Thank you very much for your kind offer—I really appreciate it!
This seems to be a reply to an existing thread. I’m not exactly sure of the context, but I suspect it’s one of your other Core Data threads, so either here or here. I recommend that you focus your efforts there rather than on this new thread.
Share and Enjoy
