The new MobileDocumentPicker for iOS is welcome addition in the latest version. I assume that in the MobileDocumentPicker.open method that the filter string is a UTI like “public.database” or “public.text”. @javier’s blog post only mentions opening PDFs. Is it possible to pass multiple UTIs as a string array (it doesn’t appear to be)? This would be extremely useful where the app can open serval different types of files.
Yep, that is possible. You can use even file type groups previously set in the IDE.
