An iOS library for introspecting live Objective-C objects by swizzling alloc/dealloc, allowing queries of all instances of a class and generation-based allocation tracking. It is archived by Facebook and only fully functional in Debug builds.
Use cases
- track all live Objective-C object allocations in an iOS app
- find memory leaks by querying instances of a class
- mark generations and inspect objects created within a scope
- count allocs/deallocs with low performance overhead
- debug retain cycles and unexpected object growth
When to choose
- you need programmatic introspection of live Objective-C instances in a legacy iOS codebase
- you want Instruments-like generation tracking embedded in your app's debug builds
When to avoid
- you need Swift object tracking or modern tooling
- you require an actively maintained library with recent support
- you need production-build allocation tracking without custom compilation flags
