EXPORT SUCCEEDED but Xcode build failed

Please, help me.
I have Ionic 3 app. I try to add cordova-plugin-facebook4.
Now When I build app by cli:
ionic cordova build ios – --buildFlag="-UseModernBuildSystem=0"
all correct:

** ARCHIVE SUCCEEDED **
and
** EXPORT SUCCEEDED **
But When I open xxxxxx.xcworkspace file and press “Run” then I get error “FBSDKCoreKit/FBSDKCoreKit.h’ file not found”
