I have an existing app, and upgraded the OS on my mac High Sierra and also Xcode from 8 to 9.1. Since then, when I try to build, I am getting an error with some shell script failing. The strangest thing is that this happens only when I try to build using my iPad device. No problems iPhone device or simulator, and no problem with iPad simulators. I tried updating all the pod files, clearing Derived Data and similar things. Below is the screenshot with all the error info. I am a newbie to iOS programming, and any help is very much appreciated. Thank you all in advance. enter image description here

  • this is a pods signing error, check your code signing settings in the pod that relates to `GTMSessionFetcher` – Scriptable Nov 20 '17 at 14:16
  • @scriptable Could you please provide some steps on checking the code signing settings for this pod? I am a newbie and still trying to find my ways around these. – Shivoham Nov 20 '17 at 15:54

This is a typical signing issue. Try delete Keychain certificates pertaining your project and rebuild using fresh ones off developer.apple.com.
