iOS Lag Monitoring and Performance Optimization Using Runloop Detection and Flame Graphs
The article describes an iOS lag‑monitoring system that uses RunLoop state checks to detect main‑thread stalls, captures and caches stack traces, employs a Fibonacci‑based annealing algorithm to limit overhead, symbolises addresses on a server, and visualises results with flame graphs while maintaining low CPU and memory impact.
