Objective-C for Rubyists
summary
Argues that modern Objective‑C actually matches Ruby on practical grounds: same dynamic runtime, duck typing, blocks/closures, and introspection, but built on C so every C program is valid Objective‑C. Demonstrates array/string/dictionary literals, automatic reference counting, message sending vs. selector dispatch and blocks for async work, shows a tiny iPhone app created and run in the Xcode simulator, and mentions dependency management via CocoaPods. Examples compile and run, and Objective‑C interoperates with Cocoa/Foundation.
