RubyMotion: Ruby in your pocket
summary
RubyMotion brings Ruby to iOS by compiling Ruby into native machine code via LLVM so apps are statically compiled and run on the unified Objective‑C runtime (no bridge). It calls Obj‑C and C APIs directly (OpenGL demo runs), applies LLVM optimizations (including TCO), and users report 50–60% less code versus Objective‑C; example app ships with runtime under 0.9 MB. Tooling is terminal/rake‑based, integrates with editors, and has ~500+ community projects and libraries like Teacup, BubbleWrap and MotionKit.
