Swift iOS App Performance Optimisation — Profiling & Fix

I will profile your Swift iOS application using Xcode Instruments and identify the specific root causes of your performance problems — slow launch time, laggy scrolling, excessive memory usage, battery drain, or UI hangs — then implement fixes and deliver a profiling report with before/after metrics confirming the improvements achieved. iOS performance problems have identifiable root causes; slow scrolling is almost always either unnecessary layout passes, image decoding on the main thread, or cell reuse misconfiguration — and all three are fixable once correctly diagnosed.

The profiling covers Time Profiler for CPU hotspots and slow functions, Allocations for excessive object creation and memory growth, Leaks instrument for retain cycle detection, Core Animation for rendering performance (offscreen rendering, blended layers, and frame rate analysis), Network instrument for unnecessary or inefficient API calls, and App Launch template for startup sequence optimisation. The top 5 performance issues by impact are fixed and the profiling report documents each finding with before/after metrics.

This service suits iOS development teams and indie developers whose app is receiving negative reviews about performance, failing App Store review for watchdog timeouts, or approaching a performance-sensitive feature launch where latency matters.
