Part II. Core Optimizations

We will now explore the core optimizations for writing efficient apps using Objective-C. These optimizations form the foundation of any app, and they must go everywhere. It does not depend on what API you use, which tier of the app you are writing at, or what exactly you are trying to achieve—these optimizations run application-wide.

The optimizations we will discuss include the following:

  • Memory management

  • Energy

  • Concurrent programming
