A quick-reference cheat sheet covering common, high-level Objective-C topics such as data types, classes, methods, properties, blocks, and common patterns. It is a documentation-style guide rather than software, aimed at developers who already know the basics.

Use cases

• quickly look up Objective-C syntax for declaring classes and methods
• refresh memory on Objective-C blocks and literals
• review naming conventions and common Cocoa patterns
• find a concise reference for properties, variables, and error handling in Objective-C
• get a PDF reference of Objective-C essentials
• compare Objective-C basics before migrating to Swift

When to choose

• you need a fast, concise reference for common Objective-C topics
• you are maintaining or reading legacy iOS or macOS Objective-C code
• you already know Objective-C basics and just need a refresher on syntax and patterns

When to avoid

• you are a complete beginner learning Objective-C from scratch
• you are starting a new iOS project where Swift is the recommended language
• you need in-depth, up-to-date coverage of advanced Objective-C topics
