@include not working on fragments

[fruitcoder]

I have the following query

query BookmarkListAllItems($id: ID!, $includeInfo: Boolean!, $batchCount: Int = 12, $cursor: String) {
  viewer {
    bookmarks(id: $id) {
      items(first: $batchCount, after: $cursor) {
        pageInfo {
          hasNextPage
        }
        edges {
          cursor
          node {
            id
            ...GQLBasicInfo @include(if: $includeInfo)
            ...GQLOtherInfo @include(if: $includeInfo)
          }
        }
      }
    }
  }
}

fragment GQLBasicInfo on SomeInterface {
  title
  ...
}

fragment GQLOtherInfo on SomeInterface {
  description
  ...
}

I use this query to get either just ids or a bunch of other info based on the includeInfo variable. When it's set to true everything works fine, but setting it to false leads to an error from the Apollo framework, which looks like this:

▿ some : GraphQLResultError
    ▿ path : 7 elements
      - 0 : "viewer"
      - 1 : "bookmarks"
      - 2 : "items"
      - 3 : "edges"
      - 4 : "0"
      - 5 : "node"
      - 6 : "title"
    - underlying : Apollo.JSONDecodingError.missingValue

So it seems that Apollo is expecting the title field to be in the response during parsing although it shouldn't care about it.

I just released Apollo iOS 0.7.0-alpha.1, which uses the updated codegen and should support @skip/@include. There have been quite a few changes to the codegen, so there might be slight differences in the generated code (especially for type conditions). That's one of the reasons I've labeled it alpha for now. Would be great if people could try it out and provide feedback!

Closing this so we can have a single issue for discussion of @skip/@include support: #74
