here my code in swift:

```auto
mutation = LoginMutation( email: "sample@gmail.com",password: "pa$$w0rd")

ApolloManager.shared.apollo.perform(mutation: mutation, resultHandler: { result in
            switch result {
                case .success(let graphQLResult):
                    if let data = graphQLResult.data {
                        print("Token: \(data)")
                    } else if let errors = graphQLResult.errors {
                        print(errors)
                    }
                case .failure(let error):
                    print(error)
            }
        })

```

I get an error in the generated file and here is the error

> Instance method ‘perform(mutation:publishResultToStore:context:queue:resultHandler:)’ requires that ‘LoginMutation’ conform to ‘GraphQLMutation’

btw I used pod file to add some references as I followed the documentation.  
here is in my podfile:

```auto
# platform :ios, '9.0'

target 'ProjectName' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for AhenteNew
  pod 'Apollo'
  pod 'Apollo/SQLite'
  pod 'Apollo/WebSocket'

end

```

I used apollo-ios-cli to generate my API but I’m not sure why it is not running. if I made the project not using the podfile the error showed while using the package dependencies, the program would work fine. I don’t know why the error saying cannot conform. please give the solution for this.
