Repeat-While Loops for Practical Programming
Course Description
Most Swift developers learn for-in and while loops early, but few ever master—or even use—repeat-while loops. This course is the only focused resource that not only teaches you how repeat-while works, but also contrasts it directly with for-in loops through hands-on coding challenges, practical simulations, and performance-minded reasoning.
Whether you're a beginner looking to understand loop types more deeply, or an experienced coder wondering when a repeat-while loop is truly the better tool, this course will teach you:
When and why repeat-while is more efficient than for-in in certain real-world scenarios.
How to use repeat-while in place of higher-overhead patterns involving enumerators or closures.
How to structure and control loops when guaranteed first execution or fine-grained iteration is critical.
What kinds of problems can be solved more clearly or safely with repeat-while logic.
We’ll walk through increasingly challenging problems that highlight where repeat-while shines—not just in theory, but in practical application. You’ll also refactor common for-in patterns to cleaner, more efficient alternatives using repeat-while.
If you're tired of loop tutorials that barely touch on repeat-while—or skip it entirely—this course gives it the attention it deserves.
By the end, you'll write smarter, more intentional Swift code with complete confidence in your control flow decisions.
