Overview

Want to create flexible and highly-interactive user experiences, while effectively managing the abundance of real-time events required? Join this hands-on, deep dive course and learn to create seamless, robust interfaces with SwiftUI and manage state over time with declarative framework Combine.

If you're finding problems using storyboards and XIBs in your iOS development with source control, and struggling with movement between code and visual layouts and ureliable connections using actions and outlets, Apple's new releases will completely alter the way you write apps. SwiftUI and Combine Swift provide an elegant way to build user interfaces for in a declarative way across all Apple platforms using a single set of tools and APIs, to dramatically simplify the process.

This Modern iOS Development course will show you how to replace familiar UIKit componenets with SwiftUI's Text and Image, create a seamless, robust interace utilising the framework's tools, create custom components, and immediately apply Combine to experiment and reinforce your functional skills.

You'll gain real experience with the most important aspects of adopting the new framework and leave feeling confident in using the features in your own apps.

Learn how to:

  • Replace familiar UIKit display components with SwiftUI’s Text, Image.
  • Work with controls such as Buttons, Sliders, Pickers and TextFields.
  • Work with containers such as VStack, HStack, ZStack and GeometryReader.
  • Draw with shapes such as Circle, Rectangle and Path.
  • Navigate with sheets, tabs and navigation controls.
  • Focus on data flow using state, bindings, observed objects, and environment.
  • Create custom components of your own and experiment with new Swift features such as property wrappers and function builders.
  • Use Combine in UIKit apps so that you can see how to apply this new framework immediately and use Combine in SwiftUI apps to experiment with the future.
  • Use existing Publishers and create your own.
  • Use standard Subscribers and create your own.
  • Use Operators to convert publishers of one type to the publishers your subscribers need.
  • Reinforce your functional skills as you apply filter, zip, map and flatMap.
