One day, one app: C game engine binds Swift native UI with C 3D rendering via shared memory
gdechichi · x · 2026-09-15
Developer gdechichi showcased his upcoming C game engine: a family app scaffolded in a single day, with native iOS UI in Swift and all 3D rendering done in C, running ultra-smooth on a phone.
The key trick is C's binding power: there's no parsing or messaging protocol between layers — Swift and C simply share memory as if written in one language, which is why the engine achieves such performance.
