Unity 6.5+ has a new Swift Project type setting, that among other things changes how the generated Xcode project is named. To handle this, use the method PBXProject.GetPBXProjectPath instead.

More information on the setting can be found here: https://docs.unity3d.com/6000.5/Documentation/Manual/ios-introducing-swift.html

Code Review

This pull request updates the iOS post-build process for Crashlytics to dynamically resolve the PBX project path using PBXProject.GetPBXProjectPath instead of a hardcoded path. The review feedback correctly identifies a typo in the newly added comment, which refers to GetPBXProjectPath as a 'Private class' instead of a private method.
