title: XCode-Project file .pbxproj - how to handle it in Version Control?
body: <p>in our team, we're using Subversion as VC-system for our iOS-projects. The problem is, that whenever one of use checks in the .pbxproj-file, the others get the CODE_SIGN_IDENTITY and PROVISIONING_PROFILE also updated with wrong values.</p>
  
  <p>Are we configuring something wrong? Is there a possibility to fix this? E.g. variables or something like that? So that the project file contains</p>
  
  <pre><code>"ARCHS[sdk=iphonesimulator*]" = "$(ARCHS_STANDARD_32_BIT)";
  CLANG_ENABLE_OBJC_ARC = NO;
  CODE_SIGN_IDENTITY = {first_variable_here-same_for_all_developers};
  "CODE_SIGN_IDENTITY[sdk=iphoneos*]" = {second_variable_here-same-for-all-developers};
  COPY_PHASE_STRIP = NO;
  </code></pre>
  
  <p>That would be really great... thanks!</p>
