    pod 'Kingfisher'
    pod 'Alamofire'
    pod 'youtube-ios-player-helper'
    pod 'Firebase/Core'
    pod 'Firebase/Auth'
    pod 'Firebase/Firestore'
    pod 'Firebase/Database'

It looks like gRPC-Core from gRPC-C++/Implementation and gRPC/Main use different version (1.14.0, 1.14.1) how to fix this ?
