title: Xcode changes remoteGlobalIDString - how to avoid?
body: <p>My "project.pbxproj" is under version control. Xcode keeps changing the <code>remoteGlobalIDString</code> of libraries linked via a subproject.</p>
  
  <p>Does anyone else have this problem? If yes, what can I do about it?</p>
  
  <pre><code>5A1F61F5162C0F6B001ABF64 /* PBXContainerItemProxy */ = {
          isa = PBXContainerItemProxy;
          containerPortal = 5A0A1B5816147A4A00C65C6D /* MyReferencedSubProject.xcodeproj */;
          proxyType = 1;
          remoteGlobalIDString = 235B356E47F64C9DB6D76F45; &lt;&lt; THIS CHANGES ALL THE TIME
          remoteInfo = MyLibInMySubProject;
      };
