Access to .xcodeproj file denied during postbuild

Hi,

I'm trying to edit the entitlement file for my OXS standalone build in a post build script.
I'm getting an access denied exception while trying to read the xcode project file:

Code (CSharp):

1.  
2. [PostProcessBuild(1)]
3. public static void PostProcess(BuildTarget buildTarget, string buildPath)
4. {
5.     var project = new PBXProject();
6.     project.ReadFromFile(buildPath);
7. }
8.  
9. UnauthorizedAccessException: Access to the path '/Users/me/Builds/MyApp/MyApp.xcodeproj' is denied.

I tried reading a test .txt file in that same folder and it worked fine, so Unity seems to have the right permissions to that folder.

Is Unity holding the project file while I'm trying to access it? I use the same code to edit the project on iOS builds and haven't had any issues.

Edit: I realised the XCode API is actually part of the UnityEditor.iOS namespace so maybe none of this is meant to be used with OSX projects?

Using Unity 2019.4.1f1 and OSX 10.15.5

Thanks

 

Hey did you ever find a solution for this? I'm running into the same problem trying to modify my Xcode project for a macOS project in Unity 2020.3.39. Did you get this to work, or did you come up with a work-around for modifying the Xcode project in a PostProcessBuild method?

 

Thanks @Alexey, that did the trick!
