You could sign up for the Claude Pro monthly payment account ($20/month) and then cancel, so that you are only trying it for one month. If you like it, you can decide whether to continue the subscription or keep it cancelled.

Did you connect to Claude via the sign-in or the api key? I did not have success signing in using the sign-in approach. Go to platform.claude.com/Settings/APIkeys and create an api key. Use the api key to get link Claude to Xcode.

I used an Anthropic API Key that I created at platform.claude.com to get Claude Agent on Xcode and logged into Claude within Xcode using my Claude account. I opened a project and asked Claude if my Pro account is connected and got the reply that the 'Credit balance is too low'. Also, I didn't need to 'Get' Claude from within Xcode as I had already created a Pro account. I'm sorry to bother you, but I am still confused. I've used ChatGPT in Xcode, but I am stuck with Claude.

@althoff That did not work for me.

@hume I"m also seeing this error when I run the app on my iPad.

I've accepted your answer. Thanks for your assistance.

@Frameworks Engineer So, I can fetch models with the SortDescriptor, but not the identifiers with the SortDescriptor because there are pending changes in the ModelContext. I guess, my question is why didn't the model fetch fail if there are pending changes, but the identiifier fetch does. But I will do as you suggest and get back with you.

@FPST This does not return any PersistentIdentifiers unless the FetchDescriptor is FetchDescriptor(). As I mentioned before, the sort does not work on PersistentIdentifiers. I had to fetch models using the sort and then stuff an array with the PersistentIdentifiers.

@FPST let fetchDescriptor = FetchDescriptor() works fine, but let fetchDescriptor = FetchDescriptor(sortBy: [SortDescriptor( .title)]) fails with The operation couldn’t be completed. (SwiftData.SwiftDataError error 1.)

@FPST I am delving into your excellent suggestion. I had issues with what turned out to be the FetchDescriptor for the fetch function. It appears that it needs to be the simplest of FetchDescriptors, so no SortDescriptors.

The more I look at this solution, the more I like it.

I see what you are saying finally about the use of ModelActor. That would solve another concurrency issue as it turns out. Thank you for your assistance.

Actually, there may be another method to fix this. I have been experimenting replacing my UIKit ViewController and CollectionView with a SwiftUI view using @query. I wonder if this will help.

In the beta version of Xcode, I set the deployment target to iOS 13 and was able to build the code.

Yes, it is Sendable.
