OP mentioned SwiftUI. Do we have a way to confirm the rows in tableView and dataSource? I don't see that way.

I see the bug happening in Safari and WKWeView. I think it is in iOS Mail app.

From the link @Frameworks Engineer gave: Impact: Processing a maliciously crafted mail message may lead to unexpected memory modification or application termination Please sit around the table and discuss how url encoded carriage returns are malicious. Consider allowing the handful of encoded characters.

No bug report yet. I've been refactoring the code, trying to determine if I've induced the crash. I have managed to view 1 of 4 similarly coded views containing this List, which puzzles me even more. I am still not sure whether the problem is in my code. Are you using 1) Core Data, and 2) List containing ForEach?

I should have written above, 'one reason...' There seems to be other reasons.

Thanks for this. Yes, it has a search bar (pre-Apple's implementation) on a List that has worked until iOS 16. The search bar is a class of ViewControllerResolver, implementing UIViewControllerRepresentable.

Thanks Ryan. However, if using CloudKit, I found the files are not stored in the '...Library/Application Support' directory, but rather in the '...Library/CloudKit/cloudd_db' directory
