In iOS and macOS(TM) Performance Tuning, Marcel Weiher drills down
to the code level to help you systematically optimize CPU, memory, I/O,
graphics, and program responsiveness in any Objective-C, Cocoa, or
CocoaTouch program.
This guide focuses entirely on performance optimization for macOS and
iOS. Drawing on more than 25 years of experience optimizing Apple device
software, Weiher identifies concrete performance problems that can be
discovered empirically via measurement. Then, based on a deep
understanding of fundamental principles, he presents specific techniques
for solving them.
Weiher presents insights you won't find anywhere else, most of them
applying to both macOS and iOS development. Throughout, he reveals
common pitfalls and misconceptions about Apple device performance,
explains the realities, and helps you reflect those realities in code
that performs beautifully.
- Understand optimization principles, measurement, tools, pitfalls, and
techniques
- Recognize when to carefully optimize, and when it isn't worth your
time
- Balance performance and encapsulation to create efficient object
representations, communication, data access, and computation
- Avoid mistakes that slow down Objective-C programs and hinder later
optimization
- Fix leaks and other problems with memory and resource management
- Address I/O issues associated with drives, networking, serialization,
and SQLite
- Code graphics and UIs that don't overwhelm limited iOS device
resources
- Learn what all developers need to know about Swift performance
