Ruckus Core (Racket Backend)

Racket handles business logic; Swift/SwiftUI provides the iOS UI layer. They communicate via the Noise RPC framework.

RPC methods are defined in ruckus-core/main.rkt using define-rpc. The Makefile runs noise-serde-codegen to auto-generate Ruckus/Backend.swift with corresponding async Swift methods. Do not edit Backend.swift manually — it is regenerated from Racket source.

Flow: ruckus-core/*.rkt → make → Backend.swift (auto-generated) + res/core.zo (bytecode)

Adding an RPC Method

1. Add (define-rpc (name : ReturnType) body) in ruckus-core/main.rkt
2. Run make to regenerate Backend.swift and recompile bytecode
3. Call Backend.shared.name() from Swift

Naming Conventions

• Racket module names should be singular (e.g. example.rkt, not examples.rkt).
