I've been working on a document-based app for well over 12 months now. It's out on the store, and everything is going well so far except for something I have been unable to solve since iOS 13.
The built-in file viewer shows all my apps files with the extension. I've rewritten the app in SwiftUI using DocumentGroup but also saw the problem with UIDocumentBrowser.
Even Apple's own Particles demo app has this issue.
I figure that it's likely a bug and there's nothing I can do about it, but I also haven't seen anyone else talking about this. So it could equally be something that I'm doing wrong.
Is there possibly a setting somewhere I need to change?
- I had a look at
NSFileExtensionHiddenbut that is already set to true. - Looking at other files in the browser - in my app - shows that those have their extension hidden. But that could just be because my app doesn't support opening them.
If your app's file have a custom extension, have you Defined that as a File Type for Your App?
If not, that could be a reason why document browser considers it part of file name without extension.
