# Theme Supporting Quote
1 Easier WASM builds with Swift I might be interested on how to build the WASM build more easier with Swift tools.” — acarette
2 Size & performance overhead vs. C/Emscripten Out of curiosity, how does the size and performance of the generated WASM compare to just compiling the same Raylib example from the equivalent C code via Emscripten? In other words, how much overhead does the choice to use Swift add here or in general?” — keldaris
3 Practical limits of Swift‑C++ interop for game dev Never ever worked for me. Imagine, you actually learned basic Swift and Raylib, now you want ‘advanced’ features in your game like navigation/pathfinding, model loading, ImGui, skeletal animation… You realize that…” — enbugger

SwiftWasmBuilder CLI

Summary

  • A command‑line tool that streamlines building WASM games written in Swift, automatically handling RAYLIB, C++ libs, and generating the JS glue code.
  • Eliminates manual WASM toolchain setup and reduces compile‑time overhead.

Details

Key Value
Target Audience Swift developers building 3D or interactive web games; indie devs using RAYLIB or other C libs.
Core Feature End‑to‑end CLI that downloads Swift‑wasm toolchain, compiles Swift sources to WASM, bundles C libs, emits JS loader and asset pipeline.
Tech Stack Swift, swift‑wasm, wasm‑bindgen, Node.js, Rust (for backend compilation).
Difficulty Medium
Monetization Revenue-ready: SaaS (Free CLI, $12/mo Team tier)

Notes

  • Directly addresses acarette’s request for easier Swift‑WASM builds and kelderis’s question about size/performance overhead.
  • Generates lean WASM binaries by stripping unused Swift runtime components.
  • Includes sample templates for RAYLIB and C++‑interop projects.

C++SwiftBridge Auto‑Bindings Generator

Summary

  • A CLI that parses C++ headers and auto‑generates Swift wrappers leveraging Swift 5.9 C++ interop, supporting overloads, templates, and smart‑pointer lifetimes.
  • Produces ready‑to‑import Swift modules for game‑dev libraries such as ReCast, OzzAnimation, and ImGui.

Details

Key Value
Target Audience Game developers wanting to integrate C++ engines into Swift‑based WASM projects; maintainers of open‑source bindings.
Core Feature Header‑to‑Swift generator with annotations for overloads, template instantiation, and lifetime tracking; outputs Swift Package compatible modules.
Tech Stack SwiftSyntax, Clang AST, Rust (parsing), SwiftPM.
Difficulty High
Monetization Revenue-ready: License $49 per concurrent user

Notes- Solves flohofwoe’s and repelsteeltje’s concerns about C++ interop complexity and lack of real examples.

  • Enables seamless use of C++‑centric libraries that otherwise require manual binding work.
  • Can be packaged as a GitHub Action for CI pipelines, encouraging community adoption.

WASM Game Deploy Platform (SwiftGameHub)

Summary

  • A hosted service where users upload a Swift game project; the platform auto‑compiles it to WASM with all necessary bindings, hosts it on a CDN, and provides a shareable URL.
  • Removes the friction of manual build pipelines and deployment for hobbyists and small studios.

Details

Key Value
Target Audience Indie devs, hobbyists, educators creating games with Swift or Swift‑WASM; community members seeking quick showcase.
Core Feature Drag‑and‑drop project upload → automatic CI build (SwiftWasmBuilder + C++SwiftBridge) → static site with embedded WASM player; optional marketplace for templates.
Tech Stack Serverless functions (Go), Dockerized Swift compiler, FastAPI, Cloudflare R2 for storage.
Difficulty Medium
Monetization Revenue-ready: 10% revenue share on paid asset sales & premium hosting tiers

Notes

  • Directly answers the community’s desire for an easier path from code to playable web game, echoing “Never ever worked for me” frustrations.
  • Provides a discovery hub, fostering discussion and showcasing viable Swift‑based game projects.
  • Low barrier to entry encourages experimentation and could grow a niche ecosystem of Swift game developers.
