Unicode character in string experiencing couldNotConvert

[tonythebully]

When trying to perform a fetch that would return a body containing unicode (in this case it is the ' character), the following error occurs:
Apollo.JSONDecodingError.couldNotConvert(value: { deviceName = "tony\U2019s iPhone"; }, to: Swift.String))

Where through graphiql and proxying through Charles, you can see clearly that the value of that variable is correctly parsed:
"metadata": { "deviceName": "tony’s iPhone" },

Solved:
The real cause of this issue was a custom SCALAR type where we were trying to pass a json object, but the parser automatically tries to pass the custom type as a string, causing a parsing error.

Referencing #94, we made some custom parsing rules for my custom type and fixed the issue.
