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.
