Swift Design Patterns

Great engineers understand design patterns because these patterns provide a standard way to solve common problems. Design patterns are especially useful when working with complex and/or large code bases, because these patterns help to make code more maintainable. Some of the design patterns included in this online course are:


Decorators enable new functionality while keeping the same interface. See examples of how decorators are commonly used in Swift and SwiftUI.


Observers can help many objects keep track of changes to a specific state. Learn how observers are often used to manage complexity in apps.


Singletons ensure there is only one instance of an object. If you've built an app before, you have interacted with singletons!


Iterators provide a way to access elements of a sequence without providing access to the underlying representation.


Composites enable small, modular components to be composed to create more complex objects and interfaces. Learn how composites are used through app and app UI implementation.

and more!

There are many more design patterns commonly used in Swift apps.

iOS Architecture

iOS architecture is important for engineers to understand because good architecture helps build and design apps that are reliable, scalable, and delight users. Understanding iOS architecture will also help you identify and avoid common software pitfalls and design errors. Some of the iOS architecture topics included in this online course are:


MVC, Model-View-Controller, is an architectural pattern that separates an app’s data model from its user interface to making developing, testing, and maintain apps easier over time. MVC is a valuable iOS architecture pattern because:

  1. UI and business logic code is kept separate
  2. business logic can be tested without launching the UI
  3. code can be better resued through shared models

This course will show the MVC pattern through commented examples and side-by-side comparisons.


MVVM, Model-View-ViewModel, is an architecture pattern that separates the view and the view model. The view model is responsible for exposing data to the view and for handling any UI logic. The view is responsible for displaying the data and for handling user input. By decoupling the view from the view model, one benefit is the view model can be tested in isolation without having to launch the entire app.

This course will show the MVVM pattern through commented examples and side-by-side comparisons.

Other Swift Architecture Topics

Understanding how to build great apps goes beyond knowing about the key architecture and design patterns in Swift. Knowing when to apply patterns, the types of problems they solve, and the benefits / tradeoffs of each one will help you build better apps. Some of the additional topics included in the online course are:


Reactivity is a pattern used to help manage and respond to events.

Dependency Injection

Dependency injection is a technique where interfaces are used to enable objects to be created from loosely coupled components improving code resuability and testing.
