PBXProject.GetPBXProjectPath

Parameters

Returns

string The path to the PBX project file. This path can be opened later using the ReadFromFile function.

Description

Returns the path to PBX project in the given Unity build path.

This function can only be used for Unity-generated projects.

Note: On VisionOS and macOS platforms this will return BUILDPATH/Unity-iPhone.xcodeproj/project.pbxproj, which isn't correct. Its not recommended to use this method when developing for visionOS or macOS.
