        From below description https://developer.apple.com/documentation/bundleresources/information_property_list/nsfileproviderdomainusagedescription?changes=_2_1__8


        The user implicitly grants your app access to a file managed by a file provider when selecting the file in an Open or Save panel, dragging it onto your app, or opening it in Finder. Your app can access that file right away and any time in the future


        In my application i select a file from open Panel and create a duplicate using CopyItem API try fileMgr.copyItem(atPath: uploadfilePath, toPath: newTempFilePath) .. I see catalina user consent coming, when i click on dont allow , i am not entering catch block and API is successful. When i checked read permissions

        FileManager.default.isReadableFile(atPath: SelectedPath) , it returns true.

          It would help if you were more specific about the code you wrote, the directory you chose the file from, and the error you got.  Failing that, I wrote a small test project to exercise this case.  The code is pasted in at the end.

          When I ran this on 10.15 and choose a file from the desktop, it’s able to successfully copy it.  I ran this outside of Xcode, just to make sure the debugger wasn’t affecting things.  In Console I saw two log entries:

          QQQ will copy /Users/quinn/Desktop/tmp.txt to /var/folders/ks/l3tlbq5x5gj6ycrwg6sv81jc0000gp/T/Test125301-300323C6-2DEE-4D19-8662-31FA68AD0343/tmp.txt
          QQQ did copy /Users/quinn/Desktop/tmp.txt to /var/folders/ks/l3tlbq5x5gj6ycrwg6sv81jc0000gp/T/Test125301-300323C6-2DEE-4D19-8662-31FA68AD0343/tmp.txt
