title: Xcode custom shell scripts are slowing down the compiling time
body: <p>Testing any changes to my Xcode project has become an exercise in patience whenever I build. After all the source files have compiled, I get the following message in the activity window at the top of Xcode:</p>
  
  <p>"Running 3 of 3 Custom Shell Scripts"</p>
  
  <p>I have not added any of my own custom shell scripts but I am using quite a few dependencies via Cocoapods and I am using 2 frameworks for the build environment, Crashlytics and Tapstream. Crashlytics requires you add a run script in the build phases, other than that I don't know where the other ones are coming from and they appear to be the bottleneck in my build time.</p>
  
  <p>Can anyone enlighten me as to what is going on and how i possibly speed it up?</p>
