Apollo-ios: Enum type causes auto generated API file to fail

[Dmurph24]

Issue:

Apollo creates an invalid auto generated file from a graphql query when it contains a enum type. When the class with type enum is generated, it extends the Apollo.JSONEncodable and Apollo.JSONDecodable classes, which do not appear to actually exist.

'JSONEncodable' is not a member type of 'Apollo'
'JSONDecodable' is not a member type of 'Apollo'

Partial Solution:

To fix this temporarily I auto generated the invalid code for this query, copied the contents, and put them into a separate swift file. To fix the 'JSONEncodable' is not a member type of 'Apollo' warning I simply changed Apollo.JSONEncodable to JSONEncodable. It seems as though if you just remove the Apollo namespace from the class extensions, this fixes the issue.

GraphQL Query:
The graphql query works fine in postman / insomnia. I can't give out the exact query, but it would be similar to this, given the knowledge of the schema below:

query Icons {
    icons {
       icon
    }
}

Schema:

        ...
        {
          "kind": "ENUM",
          "name": "Icon",
          "description": "An enum of icons used by the system",
          "fields": null,
          "inputFields": null,
          "interfaces": null,
          "enumValues": [
            {
              "name": "icon1",
              "description": null,
              "isDeprecated": false,
              "deprecationReason": null
            },
            {
              "name": "icon2",
              "description": null,
              "isDeprecated": false,
              "deprecationReason": null
            },
            ...
          ],
          "possibleTypes": null
        },
        ...

The partial solution is starting to be very tedious. I found it strange that no once else has ran into this issue.

I had this error because I have a class with the same name in an attempt to make a singleton.

class Apollo {
    static let shared = Apollo()
    let client: ApolloClient

    init() {
        client = ApolloClient(url: URL(string: ProcessInfo.processInfo.environment["GRAPHQL_BASE_URL"]!)!)
    }
}

It was fine after I renamed it. It is probably interfering with the namespace.

I am doing the exact same thing. Thanks for the response. Ill change the class name later but I'm certain that is the issue that is happening.

Oh weird! I should look into that, we've been recommending Apollo as a singleton name but maybe we shouldn't 🙃
