Error in "Loading schema for Unnamed Project" while integrating apollo ios client

Question

I am trying to integrate apollo iOS client and after doing all steps I am getting the error while running build phase script. so there are three errors in total. one is

Error initializing Apollo GraphQL project "Unnamed Project".
Error: Error in "Loading schema for Unnamed Project".
TypeError: Cannot read property 'reduce' of undefined at Object.error.

Note this accuring inside node_modules/@oclif.

Error initializing Apollo GraphQL project "Unnamed Project": Error: Error in "Loading schema for Unnamed Project": TypeError: Cannot read property 'reduce' of undefined

yes, I download the schema. actually the issue was in the schema file — M Faheem Rajput, Sep 17 '19 at 07:48
You can find info how download schema [here](https://www.apollographql.com/docs/ios/downloading-schema/). As said in previous comment this fixed the error — Taras, Feb 08 '20 at 14:14
and this error is possible through if your **.graphql** file and **schema.json** are empty. — Taras, Feb 08 '20 at 14:50

I think you need to check schema.json file inside your project, i have also faced same issue and same error but solved by adding schema.json file inside project directory

You can download it by below command

apollo schema:download --endpoint=http://localhost:8080/graphql schema.json

This worked for me! Mac users must first install the apollo-cli via homebrew: brew install apollo-cli – Jochen Holzer Apr 20 '21 at 10:17

first you should add this command npx apollo service:download --endpoint= schema.json

then run this command npx apollo codegen:generate --localSchemaFile=graphql-schema.json --target=typescript --tagName=gql

Please describe why these command resolve the issue? – sorosh_sabz Oct 06 '21 at 20:16
Thank you, this helped me. I had already linked the schema URL and it kept throwing errors for some reason. When I executed below lines, it worked like a charm for me. npx apollo service:download --endpoint= graphql-schema.json – ShrawaniSilwal Nov 11 '21 at 15:24
