Build iOS Apps with SwiftUI

We’ve got a fully functional APIRequest helper class that we can use for all sorts of requests! If we want to support more features in the future, we can extend this class, but our API helper is now more than capable of handling all our needs. Now, when we want to implement a new action, we can make a new instance of APIRequest and provide the necessary parameters and completion handlers.

  • Don’t write unit test for your View Model to verify the user interface.
  • By doing this, we can easily access PodcastPlayer by defining it with @EnvironmentObject Property Wrapper.
  • Robert does a great job of incorporating many SwiftUI features into an app so you can see how they all work together.

You’ll even get AI-driven recommendations on what you need to review to help keep you on track. Learn about functions and structures and use them to start building the logic for Code History.

Creating custom SwiftUI container views

Now, let’s integrate failure cases in our APIRequest class. I marked the added lines of code with comments, so you can spot what was added. We have already implemented many essential components of our first SwiftUI app. In the previous part, we applied the necessary logic for our authorization. In our LoginAction class, we have everything we need to send an API request to our mock server.

I’ve completed all sections at this point, except the few lectures unpublished in Africa App. I would say that Robert’s style of teaching is really a «Learn by Doing» model. If you’re completely new to Swift and SwiftUI it might be a bit intimidating, since he dives right into it. However, if you’re open to learning through what you’re exposed to and reading up on aspects of the language and SwiftUI framework, I find it very engaging and just so well developed.

Swift UI Layout Your First iOS and SwiftUI App with Xcode 11 Swift 5 1 and iOS 13

Our helper class is pretty powerful at this point! However, we can add a couple more things to our APIRequest to improve it further. But our APIRequest class is not powerful enough yet.

Also he is completely up to date with SwiftUI and iOS so you get guidance on how to use the latest features available. You should probably not nest ObservableObjects either — that’s not really a supported paradigm in SwiftUI. Also, be aware that your ExternalClass would get re-created on every render of your View.

Advanced SwiftUI Animations – Part 5: Canvas

Let’s create together a modern E-commerce mobile application with the SwiftUI in Xcode. This time, we will develop a realistic iOS app prototype and cover some essential programming concepts. This guide is featuring all major updates and improvements of Apple’s native user interface framework. From totally beginner to advanced iOS app developer with this complete iOS 16 SwiftUI 4 development course programming in Xcode 14. When you’re finished with this SwiftUI tutorial, you’ll have the skills and knowledge of SwiftUI needed to build complete apps for Apple platforms.

  • Basically, once we’re done with this helper class, it will be generic, meaning we won’t need to change it — or we will do it very rarely.
  • Take a deep dive into the Swift language, learning about core Swift concepts like loops, collections, types, optionals, functions, classes, and more.
  • Now that your SwiftUI skills are starting to solidify, it’s time to review all the new things we’ve covered and get busy with another project all of your own.

During his travels, he wrote a book which now has 35,000 readers. You’ve learned about data, data, and some more data, so it’s time to pause and reflect on what was covered before tackling another new challenge. SwiftUI Lessons As we discussed in the previous chapter, we can pass custom objects into the Environment of a View hierarchy inside SwiftUI. But SwiftUI already has an Environment populated with system-wide settings.
