Collection transformations and optimizations

In this chapter, we'll delve into the art of manipulating and optimizing collections in Swift. From arrays to dictionaries, you'll explore a variety of techniques that enhance the functionality and performance of these fundamental data structures. We'll cover everything from sorting arrays with closures and mapping with key paths to efficiently transforming dictionary values and utilizing lazy collections for resource management.

This chapter will equip you with the skills to handle large datasets, implement type-safe operations, and ensure your collections are both efficient and easy to manage. By the end of this chapter, you'll be well-versed in leveraging Swift's powerful features to manipulate collections in a way that is both memory-efficient and optimized for performance, making your applications faster and more reliable.
