Users notice performance immediately.
Slow launches, dropped frames, memory leaks, and battery drain can turn even well designed apps into frustrating experiences. Performance is not an extra feature. It is a core part of quality.
"iOS at Speed" is a practical, engineering focused guide to optimizing applications for Apple platforms using modern Swift development and professional performance engineering techniques.
This book teaches you how to analyze, profile, and optimize iOS applications the way experienced mobile engineers do in production environments.
Why performance engineering mattersAs applications grow more complex, developers face problems such as:
sluggish interfacesexcessive memory usagebattery drainanimation stutteringstartup delayscrashes caused by resource pressureThis book shows you how to identify and eliminate these issues systematically.
