How to serialize GraphQLEnum JSON in swift with Apollo version 1.3

I am trying to serialize data from a GraphQL Apollo request into JSON in order to decode into my swift model. However, when trying to serialize the data with an enum it fails.

static func decodeUser(userJson:JSONObject)->UserQL?{
        let decoder = JSONDecoder()
        print(userJson)
        guard let jsonData = try? JSONSerializationFormat.serialize(value: userJson) else {
            return nil
        }
        return try? decoder.decode(UserQL.self, from: jsonData)
    }

Below is my User DTO

struct UserQL:Codable,Equatable{
    var id:String
    var username:String
    var userType: UserType
    var photoUrl:String?
    var createdAt:String?
    var bio:String?
    
    enum CodingKeys:String,CodingKey {
        case id,username,photoUrl,createdAt,bio,userType
    }

I have tried changing userType to GraphQLEnum, however, that does not do anything. I was able to find a fix by changing the userType on the type User in the schema to String! because the enum is piped across as a String, then defining the enum in swift

I’m hoping to be able to avoid that though, because then my schema won’t match across platforms.
