Drive Complex Logic with while loops

Most Swift courses teach for loops well enough — iterating over arrays, using ranges, and walking through collections. But when it comes to while and repeat-while loops, they’re often treated as leftovers: briefly introduced, rarely practiced, and almost never applied to real-world programming problems.

This course is here to fix that.

“Drive Complex Logic with while loops” is built for software engineers who already know the basics of Swift but want to master control flow that depends on state, not structure. In other words, you’ll learn how to drive your program forward based on conditions, not collections — a critical distinction when building anything from stream processors to user input loops, algorithmic systems, or reactive app logic.

In this course, you’ll go deep into:

• Entry-controlled (while) vs exit-controlled (repeat-while) loops — how they differ, when to use each, and why it matters

Along the way, you'll solve dozens of short coding challenges designed specifically to exercise conditional looping. These aren’t filler exercises — they model the kind of edge-sensitive, state-dependent, or exit-controlled logic real engineers write in real projects.

This course assumes you already understand basic Swift syntax and have written simple functions, loops, and conditionals. If you've built simple apps or worked through a beginner Swift tutorial, you’re ready.

By the end, you'll not only understand how while loops work — you'll know why they exist, when to use them, and how to structure your code around them in ways that make your logic more expressive, readable, and powerful.

If you’ve ever written a for loop where it felt like you were forcing it to do something unnatural — this course is for you.
