JRSwizzle is a small Objective-C source package providing a single, correct, and consistent API for method swizzling (exchanging method implementations) across many versions of Mac OS X and iOS. It handles runtime architecture differences and inheritance edge cases that naive swizzling implementations get wrong.
Use cases
- swizzle an Objective-C method at runtime
- exchange method implementations in an iOS app
- patch UIKit or AppKit behavior without subclassing
- instrument existing Objective-C methods for logging or analytics
- avoid swizzling bugs with inherited methods on 64-bit iOS
When to choose
- you need battle-tested, correct method swizzling on Apple platforms
- you must support old OS X/iOS versions or multiple runtime architectures
- you want simple one-line swizzling with NSError diagnostics
When to avoid
- you are writing Swift-first code and prefer modern alternatives
- your project avoids runtime monkey-patching entirely
- you need actively developed features beyond swizzling
