I am so much frustrated due to lack of documentation of Apollo ios. it has been more than a week I am trying to use graphQL in my ios app. I resolve all errors but now stuck in this one and don’t know the solution. one thing which I have noticed in this project is lack of compatibility with old and different version os required libs.

To make it run you have to update from Xcode (swift 5).
Than update cocoa pods gem because old cocoa pods will not download the new version of apollo pod. its weird.
update Node because Apollo package needs it.
etc and once you are done with all errors do pray for this library works.

ok, I found that the schema.json was generate from web doc is wrong, so I try to download the file by command line.

Install apollo:

# npm install -g apollo@latest

Check installing successfully:

# apollo -v

it should show: apollo/2.31.1 darwin-x64 node-v12.18.3 … or something like that

Download schema.json:

# apollo schema:download --endpoint=YOUR_SERVER_URL/graphql schema.json

Then open folder to see schema.json file:

# open .

Then use schema.json somewhere you want, I hope these information can help someone else

For me wrong schema downloaded. Wrong: apollo schema:download --endpoint=YOUR_SERVER_URL/graphql schema.json Right: apollo schema:download --endpoint=YOUR_SERVER_URL/query schema.json

Hey guys, it can be you have wrong schema.json and .graph files, so you should try correct file here to test: https://www.raywenderlich.com/595-getting-started-with-graphql-apollo-on-ios ZIP: graph.zip
