I am following this tutorial: iOS GraphQL Simplified: macOS Command Line Techniques for Sustainable Schema Operations | by Alkin Cakiralar | Medium and I am getting an error when using the generate command. It seems to be an issue with my schema, but it is the one I get when I run ./apollo-ios-cli fetch-schema . Has anyone else had the same problem? How can I resolve it?
This is my structure in the Xcode project:
graphql_schema_Rick.graphql:
