When I try to Archive my application on Xcode 7.3.1, I am getting following error:
error: Invalid bitcode version (Producer: \'800.0.35.0_0\' Reader:
If you are using lib or pod that mean that one of them built by a higher version of your current Xcode, you can either update your code or return back to the previous version where the pods were built by your current version. If you ran pod update check the pods updated if you ran pod install check the dates of the pods comparing to the release date of your Xcode that will will lead you to the responsible pod.
I got it while I was building using Xcode 8.2.1 and the pod built by Xcode 8.3.1
