I have existing macOS application
the application is distributed via pkg
now I need Mac App Store version

I store application data in ~/Documents/MyApp
ideally i wan’t to keep using same folder

1. With pkg it’s rather simple, application asks for ~/Documents permission once

<key>com.apple.security.temporary-exception.files.home-relative-path.read-write</key>
<array>
<string>/Documents/</string>
</array>

2. but for sandbox it’s forbidden as I see
i can only use:

<key>com.apple.security.files.user-selected.read-write</key>
<true/>

now app creates folder in ~/Library/Containers/com.my.app by default

• Is it possible to request same permission once and continue using ~/Documents/MyApp folder?
• Better to use Migration using container-migration.plist?
• Any other possible options?

Thanks in advance!

I tried to use NSOpenPanel, after selection it’s fine

But it looks like User need to select folder at each application launch?

    NSOpenPanel* openPanel = [NSOpenPanel openPanel];
    openPanel.prompt = @"Select";
    openPanel.message = @"Please select Documents folder";
    
    openPanel.canChooseFiles = false;
    openPanel.allowsOtherFileTypes = false;
    openPanel.allowsMultipleSelection = false;
    openPanel.canChooseDirectories = true;
    openPanel.directoryURL = [NSURL URLWithString: @"~/Documents/"];
    
    NSModalResponse response = [openPanel runModal];
    
    if (response == NSModalResponseOK) {
        NSLog(@"OK: %ld %@", response, [[openPanel URLs] lastObject].absoluteURL);
//possible to use/create MyApp folder
    } else {
        NSLog(@"Error: %ld", response);
    }
