Apollo Codegen (apollo-codegen)

CLI tool to generate typed client code (Swift initially, later TypeScript/Flow) from GraphQL schemas and query documents. Version 0.4.0 is early stage — only Swift output, no fragment support beyond exact type matches. Unstable API. Superseded by @graphql-codegen/cli (v1+) and Apollo CLI. Releases were sporadic. Differentiated as first codegen from Apollo, but quickly replaced.
