Large Memory Allocation Monitoring Solution for iOS Applications

A low‑overhead monitoring solution for iOS apps resets the global malloc_logger to capture every allocation, filters large allocations exceeding a configurable threshold, records lightweight stack traces using dyld image maps, and sends address‑only data for offline symbolication, enabling developers to identify and fix memory‑heavy code, reducing OOM crashes.
