Best use case

objective-c is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Objective-C for legacy iOS/macOS development with manual memory. Use for .m files.

Teams using objective-c should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# Objective-C

Objective-C is in **maintenance mode**. New features are rare, but it powers the Apple ecosystem's foundation. It allows mixing C++ (`.mm`) loosely.

## When to Use

- **Legacy iOS/macOS**: Maintaining apps created before 2014.
- **C++ Interop**: Obj-C++ is often the bridge between C++ engines and Swift.
- **Runtime Swizzling**: Dynamic method replacement (used by Analytics SDKs).

## Core Concepts

### Message Passing

`[object method:argument]`. Dynamic binding at runtime.

### ARC

Automatic Reference Counting. (Retain/Release).

### Headers

`.h` (interface) and `.m` (implementation).

## Best Practices (2025)

**Do**:

- **Use Nullability Annotations**: `nullable`, `nonnull` to aid Swift interop.
- **Use Modern Syntax**: `@[@"a", @"b"]` for arrays.
- **Migrate to Swift**: New features should be written in Swift.

**Don't**:

- **Don't use manual retain/release**: Always ensure ARC is on.
