Xtrace is an Objective-C library (a header and C++ implementation file) that intercepts and logs all method calls to a class or specific instance using the Objective-C runtime. It is primarily useful for debugging iOS/macOS apps and has been superseded by the author's SwiftTrace project.

Use cases

• trace all Objective-C method calls to a class
• trace method calls on a specific object instance
• trace an entire app bundle or embedded framework's classes
• trace all UIKit methods matching a class name pattern
• dump pseudo-header of a class from lldb
• colorize method traces in Xcode console

When to choose

• you need to see every Objective-C method call made to a class or instance for debugging
• you want to explore undocumented framework behavior by observing method traffic
• you work in an Objective-C codebase and want a lightweight, header-only tracing tool

When to avoid

• your project is primarily Swift - use SwiftTrace instead
• you need actively maintained tooling - the project is superseded and last released in 2021
• you need production-safe tracing rather than a development-time debugging aid
