Advanced Memory Debugging with Xcode Tools
summary
Xcode memory tools reproduce real leaks: the memory usage viewer shows spikes, the memory graph snapshot reveals strong reference cycles, and the live demo proves fixes work. Examples include changing delegates to weak and adding `AnyObject` to protocols so weak applies, converting a closure capture to a weak cell capture, and removing stuck view controllers. Verification shows fewer retained instances and a runtime drop of about 1-2 MB after fixes.
