Tools You Will Master
Instruments
Go beyond basic debugging. Learn deep profiling of time, allocations, and energy usage to surgically remove inefficiencies.
Memory Graph Debugger
Visualize your object graph to hunt down retain cycles and ghost objects that are silently draining user battery and memory.
Build Settings
Master the compiler. Configure optimization levels, debug information format, and architecture settings for peak performance.
Asset Catalogs
Implement efficient image slicing, vector support, and app thinning to significantly reduce the download size for end-users.
Hear from Performance-Focused Devs
David Chen
Senior iOS Engineer"The section on Instruments alone was worth the price. I found and fixed a major memory leak in hours that had been plaguing our production app for months."
Sarah Miller
Indie Developer"We reduced our app size by 15% using the techniques from Module 5. That optimization directly impacted our download conversion rate in emerging markets."
James Thorne
Lead Architect"This is the deep, technical content I've been looking for. No fluff, just actionable advice on concurrency and memory graphs."
