I'am trying to upgrade "react-native" from "0.50.4" to "0.55".
When I run pod install, i receive an error

Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.I am a beginner in react-native and I can not make a pod install in my iOS project.Thank you in advance.
