You will receive a free update later this year. If you want to start learning SwiftUI, check out the book here. Note: We are updating our Mastering SwiftUI book for iOS 16. If I miss any great updates, please do leave a comment below and let me know. I’m still exploring the new APIs of SwiftUI. The Charts API, the revamp of navigation view, and the introduction of AnyLayout will definitely help you build more elegant and engaging UIs. This year, Apple once again delivered tons of great features for the SwiftUI framework. We are using 0.00 as a placeholder for now. The VStack that groups together the Current Balance Text view and another Text view that will be responsible for displaying the dynamic account balance. A Spacer that adds 50px of space from the top of the screen. This is a more complex topic, so we will discuss this new protocol in another tutorial. The VStack that will hold all the content on our screen. What if those layout containers are not good enough for arranging the type of layouts you need? The Layout protocol introduced in iOS 16 allows you to define your own custom layout. In most cases, we use SwiftUI’s built-in layout containers like HStack and VStack to compose layouts. Say, for example, you rotate an iPhone 13 Pro Max to landscape, the layout changes to horizontally stack view. regular ? AnyLayout ( HStack ( spacing : 0 ) ) : AnyLayout ( VStack ( spacing : 0 ) ) IOS 16 introduces the ShareLink control for SwiftUI, allowing developers to present a share sheet. Say, you can create a button for you to jump directly to the main view from any detail views of the navigation stack. With the new navigationDestination modifier, you can programmatically control the navigation. That said, it’s just a quick overview of the new NavigationStack. This is how the new NavigationStack works. It then calls up the destination view which associates with that specific item type. Each subsequent array is appended to the bottom of the previous array. When a user selects a particular item in the navigation stack, SwiftUI checks the item type of the value of the navigation link. The Excel VSTACK function combines arrays vertically into a single array. In the code above, we have two navigationDestination modifiers: one for the text item and the other is for the color object. When this pairs with the new navigationDestination modifier, you can easily control the destination view. Instead of specifying the destination view, it can take a value that represents the destination. In iOS 16, the NavigationLink view is further improved. One is a text item and the other is actually a Color object. However, the underlying type of these two rows are not the same. The list above is simplified with only two rows: Text item and Purple color.
