Logging and debugging

This chapter dives into essential debugging and logging techniques in Swift, focusing on tools and practices that enhance error detection and program analysis. You'll learn how to use assertions to catch logical errors early in the development process and enrich debug logs with contextual information for clearer insights. We'll explore how to implement custom nil-coalescing in debug prints and customize output with CustomDebugStringConvertible for more informative debugging. Additionally, we'll look into techniques for introspecting properties and values at runtime, along with utilizing the dump() function for in-depth analysis.

These strategies will equip you to effectively debug and refine your Swift applications, ensuring they run smoothly and efficiently.
