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.

Why Take This Course?

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.


VIPER Architecture

In this lesson, you’ll learn about increasingly popular VIPER architecture. VIPER is a structural design pattern that can be used as a replacement for the Model View Controller (MVC) pattern. VIPER addresses one of the most common problem with MVC, massive view controllers, by splitting up typical MVC responsibilities into more concise and coherent classes.
