It seems like that the new update of Xcode is targeting devices with iOS versions from 8.0 up to 12.0.

Open your Xcode and there is File upper-left next to Apple icon, then open Workspace Settings and change the build system to Legacy Build System.

@zsirfs You are my hero! I've been updating to Legacy Build System in my .xcodeproj file and editing scripts for the past day until I found this post saying to update it in the .xcworkspace file. Much appreciated :)

pod update worked for me.
From your terminal, go to your projectRootPath/ios then run 'pod update'.
