Xcode 10 Command PhaseScriptExecution failed with a nonzero exit code (EXPANDED_CODE_SIGN_IDENTITY: unbound variable)

This helped me sudo gem install cocoapods –pre pod update I’ve read BugReport. Problem was similar to mine and it was fixed in 1.6.0.beta.1 (2018-08-16) (changelog). Updated(thanks to Cœur) 1.6.0 (2019-02-07) Was published sudo gem update cocoapods This should work now.

error: Couldn’t IRGen expression, no additional error [duplicate]

I had same issue with Carthage. However while looking more closely at console I’ve spotted that Carthage instead of building RxSwift just downloaded pre-built binaries, *** Downloading RxSwift.framework binary at “Zürich” that in turn contribute to IRGen error. So forcing Carthage to build framework instead of downloading binary worked. carthage update –platform iOS –no-use-binaries
