Memory Debugging

关于

This skill provides a comprehensive framework for identifying and fixing memory issues in xOS development. It guides developers through a 'diagnostic first' approach, leveraging tools like the Xcode Memory Graph Debugger and Instruments to differentiate between normal memory spikes and progressive leaks. By covering common failure patterns—such as timer retain cycles, unmanaged observers, and closure captures in collections—the skill ensures that apps remain stable over long-term usage and avoid memory-pressure-related crashes.
