title: iOS - Build fails with CocoaPods cannot find header files
body: <p>I have an iOS project using CocoaPods. Everything was working smoothly until another developer started to work on the same project. He made some changes (only to code as far as I know) and made a new branch in the repo. I have checked out his branch and tried to build it, but I am getting an error: ASLogger/ASLogger.h file not found. </p>
  
  <p>Even if I delete the whole project and make a fresh copy and use 'pods install .' the build failure is still there. Do you have any idea where the problem can be? If you need some more infos, just ask.</p>
