If your iOS project requires additional Xcode frameworks, use the PBXProject API to add those frameworks to the Xcode project files created by Unity Cloud Build.
There are two ways to call this API to manipulate the Xcode project:
Use the built-in Unity PostProcessBuildAttribute, which is executed before the Unity Cloud Build Post-Export method runs.
Use the Unity Cloud Build post-export method.
Note: if you are using a version of Unity earlier than 5.0, add this functionality to your Unity project using the Xcode Manipulation API provided by Unity on Bitbucket.
