RubyMotion: Rubyizing iOS development
summary
RubyMotion compiles Ruby to optimized machine code with LLVM, keeps ARC-style memory management, and exposes the Objective‑C runtime so native APIs, storyboards and CocoaPods work. The demo shows a REPL controlling the simulator—adding a segmented control, moving it, and live-inspecting views—using gems like bubble-wrap and sugarcube. Build uses rake (default, spec, archive), produces IPA for App Store, supports vendor projects and C bridging, and runs mac-bacon tests in the simulator. It costs ~$200, lacks a full debugger, and three apps are already built.
