Common Problems, Common Solutions
In this course, you'll explore popular iOS design patterns — the practical and battle-tested solutions to common problems that are used everyday by professional developers. You'll take a look at architectures and mechanisms that are used for constructing large, complex apps. And, by the end of this course, you'll have accumulated a reliable toolset of patterns that you can apply to your own projects.

If an app grows without a stable infrastructure, then it is doomed for failure. To avoid this, developers rely on, and apply, design patterns to control complexity, limit duplication, and build quality, scalable apps. By taking this course, you are preparing yourself to work in larger iOS codebases — utilizing and implementing design patterns to solve bigger and bigger problems.
