Thanks for showing your code. (Have you used Paste and Match Style when pasting your code? That will prevent adding extra empty lines.) Can you clarify which platforms is your app targeting?

Can you show your code?

Thanks for showing the code of PersistentStack. Simply saying, your two codes, in Swift and in Objective-C, are completely different in instantiating and setting up managedObjectContext and persistentStoreCoordinator. If you want to make your Swift code work as the same as Objective-C code, do the same thing.

Not many readers would like to go deep into external links. You should better show any of your codes as text as far as you can.

Thanks for trying and sharing the new code. But I cannot find any critical issues with a glance. But, anyway, if your newly built Objective-C app runs as expected, your Swift version of the app should also work (if you correctly implement all things in your Objective-C code), even though NSPersistentStoreUbiquitousContentNameKey was deprecated long ago. Have you checked all the ids and the names are the same in Objective-C project and Swift project?

People who has done a tutorial recently would rarely try to write an answer on Q&A sites. Please show enough code to appeal to readers who can say something.

Generally, you should better think that embedding a NavigationView inside TabView is not supported. Better start a lot of additional work now. Or, if you expect some readers would be able to solve your issue, you can start your own thread.

Even created a new objective-c app and migrated the code needed to interact. Do you say that your newly created Objective-C app cannot get data from iCloud documents? Then it is not a problem of migrating Swift. And as iCloud Documents is in a process of closing, it is reasonable new apps would not be able to use it.

Can you show what you think is the RIGHT answer?

@AnimalOnDrums, I am using the latest version of Xcode Are you sure you are using Xcode 13.1? Xcode 13.0 does not contain macOS SDK 12.

I know many developers are suffering this UIButton issue. Have you sent a feedback to Apple?

@jkspiezio, thanks for clarifying. Can you try creating a project which can reproduce the issue, but not using Firebase thing? Unless your code is doing something obviously wrong (and in this case, it is not), it is hard to say something sure with just seeing the code. By the way, you should better show your latest code, as editing old post is quite limited, you may need to use Your Answer to show some updates to your question.

One thing clear is that your predicate does not satisfy the requirement documented. Maybe you have some experiences implementing functions like min and max, and your mind is bound to such experiences. Free yourself from experiences, any frameworks or libraries might not work as you experienced.
