The linker command failed with exit code 1 error

I build my game from Unity to Xcode, the game has GameAnalytics and GoogleMobileAds SDK, I opened the .xcworkspace file with Xcode (Version 9.2), but when I try building it (for Simulator and also for real device) I always got this error:



ld: warning: -undefined dynamic_lookup is deprecated on iOS ld: framework not found CoreServices for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)


Can you please tell me what's wrong? and how to solve it.
