Build Swift

Swift is a modern and intuitive programming language that ranks among the top programming languages for mobile app development. 

Originally developed by Apple, Swift is now the recommended programming language for developing apps for all Apple platforms including iOS, iPadOS, macOS, tvOS, and watchOS. If you plan to write an app for an Apple device, you will need to learn to program in Swift.

In this course, you will cover topics ranging from basic data types, constants and variables, arrays, dictionaries, object-oriented programming, logic and control flow, file and file system management, and error handling.

On completion of this course, you will have sufficient foundational knowledge of Swift programming to begin learning other areas of Apple-based app development such as SwiftUI.

Swift Programming for Mobile App Development

Now that the topics of Swift classes and structures have been covered, this chapter will introduce a related topic in the form of property wrappers. Introduced in Swift 5.1, property wrappers provide a way to reduce the amount of duplicated code involved in writing getters, setters, and computed properties in class and structure implementations.

Learn what Swift property wrappers are,  and explore how they provide a useful way to make computed properties reusable across different classes.
