Missing permissions with CloudBuild on iOS

Hi,
I'm having troubles with my game that uses Vuforia to do Augmented Reality since I've updated from Unity 2017.4.1f1 to Unity 2018.2.15f1

When I export an xcode project from Unity and then launch it on my iOS device, everything is fine, camera permission is asked at the beginning and Vuforia works flawlessly.

However, if I use CloudBuild to generate the package, the camera permission is never asked and therefore Vuforia isn't working.

I already tried this kind of fix without success
https://forum.unity.com/threads/missing-camera-permissions-in-ios.446033/

I didn't had this issue before the migration to Unity 2018, and I can't figure what to do.

Thanks for any help

 

That plist modification approach should work, in general. Here's what we use for Photo library:

Code (CSharp):

1.  
2. public void OnPostprocessBuild(BuildReport report)
3. {
4.     // Open the Info.plist
5.     string pathToBuildProject = report.summary.outputPath;
6.     var plistPath = Path.Combine(pathToBuiltProject, "Info.plist");
7.     var plist = new PlistDocument();
8.     plist.ReadFromFile(plistPath);
9.  
10.     // Set photo gallery permission string
11.     plist.root.SetString("NSPhotoLibraryUsageDescription", "Your photo library permission string here");
12.  
13.     // Apply settings to Info.plist
14.     plist.WriteToFile(plistPath);
15. }

For 2018, this code should live in a class's OnPostprocessBuild function like documented here: https://docs.unity3d.com/ScriptReference/Build.IPostprocessBuildWithReport.OnPostprocessBuild.html
