Hey here I am two years later answering my own question. Thanks past Slif! 🙇‍♂️

@Rumio - Same here, in Xcode 16.2 (16C5032a) I continue to receive that error. CoreData: Declared Objective-C type "[NSInteger]" for attribute named perkLevelRequirementsIntArray is not valid

@neonrt @DTS Engineer I'm also trying to figure out how to silence this warning, as it is (expectedly) coming from a closed-source library in my project. I've been combing through various means by which warnings can be silenced, but have been unsuccessful in ascertaining how those methods apply to this warning. Any trail I can pick up on?

Done! Feedback FB15621066 submitted and attachments uploading now.

Likely a dependency or library feature you're using, but at least your warning makes sense. I was (and still am) getting this warning weeks/months before 14.4 was released.

This is what did it for me! The name of the file was "Font_Name.otf" but the name of the font was "fontname" which meant Font.custom("Font_Name") wouldn't work. Great link, thank you!

Thank you for the writeup!

How did you end up solving it?
