Xtrace
Trace Objective-C method calls by class or instance
...Logged information can include selectors, arguments, return values, and calling functions. Developers can exclude classes, selectors, or problematic data types before tracing begins. A basic profiling interface can rank intercepted methods by accumulated execution time. The project is now superseded by SwiftTrace and mainly serves as a historical runtime-inspection tool for older Objective-C, iOS, and macOS applications.
