I already have made a codegen using apollo-ios-cli, now I want to generate code for a new set of operations with different schema.  
Do I have to modify the existing apollo-codegen-config.json or create a new one? If I have to create new one, how does the apollo-ios-cli know which file it has to use for ‘generate’?

Hi @Anil 👋 - if you want to be able to regenerate both at any time then a new codegen config file is the best approach, and to keep both with your project. I would give them names related to the schema for each.

The CLI `generate` command supports a [`--path` parameter](https://www.apollographql.com/docs/ios/code-generation/codegen-cli#generate) which lets you specify which config file should be used. By default, if you don’t specify `--path` then it looks for a file named `apollo-codegen-config.json `.
