Apple rejection. NSAppleMusicUsageDescription

[gusabdala]

🐛 Bug Report

Apple rejects due to not defining NSAppleMusicUsageDescription even when not needing this permission.

Expected behavior

Should be able to disable this via preprocessor definition.

Reproduction steps

Configuration

Version: 5.0.0+hotfix.6

Platform:

• [x] :iphone: iOS
• [ ] :robot: Android

@mvanbeusekom Is this something you could resolve?

[smasinde]

What I did, and what others have suggested is to add it to the info file and state that your "app does not use this permission, if requested please reject." It shouldn't ever call though.

If you want to disable it completely, this seems to work I haven't tried it. https://github.com/Baseflow/flutter-permission-handler/issues/26#issuecomment-605026503

@gusabdala you can mention dummy permission like this in info.plist

<key>NSAppleMusicUsageDescription</key>
<string>This permission is not needed by the app, but it is required by an underlying API. If you see this dialog, contact us.</string>

I've seen this before and the reason (from my understanding) is because if an underlying SDK or framework requires a certain permission for a specific feature (regardless of whether you implement that feature), you need to include that permission in your plist. The reasoning being, if somehow that code is triggered and the permission isn't accounted for in the plist, it will cause a crash and from my experience Apple review won't allow for such a possibility.

I would echo the comments from @smasinde and @shahnawazahmed88

Any updates!

Can someone confirm the contents of the ios/Podfile?

Also which version of the plugin are you using?

Here is mine,

    return matches[1].strip if matches

please note, I had to add those lines to my info.plist

<key>NSAppleMusicUsageDescription</key>
<string>This permission is not needed by the app, but it is required by an underlying API. If you see this dialog, contact us.</string>

[mvanbeusekom]

I am assuming you are using a version of the permission_handler before 8.0.0, where permission are all enabled by default (this behavior is flipped since version 8.0.0 and higher). In this case the reason is because the PERMISSION_MEDIA_LIBRARY is enabled (commented out in the ios/Podfile).

The PERMISSION_MEDIA_LIBRARY macro enables/ includes the iOS MPMediaLibrary framework which in turn requires the NSAppleMusicUsageDescription in the Info.plist. If you don't need access to the devices media library you can remove the comment character in the ios/Podfile for the PERMISSION_MEDIA_LIBRARY macro.

Hello, any updates regarding this ?

[mvanbeusekom]

Closing this issue as the problem is caused by misconfiguration (see comment).
