Whenever you are doing any performance measurement, do it in release mode. The Swift compiler performs many optimization steps in the release mode and dramatically increases performance. To set release mode, go to Product | Scheme | Edit Scheme | Run, and adjust the Build Configuration setting to Release. Always use release mode for performance testing.

Overview of this book
Swift is one of the most popular and powerful programming languages for building iOS and Mac OS applications, and continues to evolve with new features and capabilities. Swift is considered a replacement to Objective-C and has performance advantages over Objective-C and Python. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun.
Develop Swift and discover best practices that allow you to build solid applications and optimize their performance.
First, a few of performance characteristics of Swift will be explained. You will implement new tools available in Swift, including Playgrounds and REPL. These will improve your code efficiency, enable you to analyse Swift code, and enhance performance. Next, the importance of building solid applications using multithreading concurrency and multi-core device architecture is covered, before moving on to best practices and techniques that you should utilize when building high performance applications, such as concurrency and lazy-loading. Finally, you will explore the underlying structure of Swift further, and learn how to disassemble and compile Swift code.
