VoiceOver navigation support in your apps comes with the same requirements as navigating through touch controls. When navigating apps with standard touch controls, we tend to dislike apps that feel cluttered or make us do many interactions to achieve something. We'd probably say such an app does not offer a ...

The @ViewBuilder attribute is one of the few result builders available for you to use in SwiftUI. You typically use it to create child views for a specific SwiftUI view in a readable way without having to use any return keywords. I encourage you to read my article Result builders ...

Adopting the UIViewRepresentable protocol allows you to host UIView instances in SwiftUI. Your SwiftUI code is converted to UIKit views behind the scenes. SwiftUI requires you to declare the view representation, but the underlying SwiftUI implementation will optimize how final views are drawn on the screen. You can use a ...

NavigationLink in SwiftUI allows pushing a new destination view on a navigation controller. You can use NavigationLink in a list or decide to push a view programmatically. The latter enables you to trigger a new screen from a different location in your view. Allowing to push a new screen onto ...

SwiftUI comes with built-in markdown support for text, making it easy to transform the text into bold, italic, and other formats. iOS 15 and SwiftUI 3 introduced support taking away the need to combine text weight for similar results. Markdown isn't wholly supported (more on that later), but many features ...

Downloading and caching images is an essential part of building apps in Swift. There are several ways of downloading images with 1st party APIs 3rd party libraries. In my experience, every developer has their way of handling remote images since there's no go-to standard. SwiftUI introduced AsyncImage as a 1st ...

Animations in SwiftUI look great and make your app shine, but sometimes you want to disable animations on a specific view since it doesn't look great when animating. Compared to UIKit, SwiftUI makes it easier to create animated transitions between two states using the animation view modifier. You can see ...

Presenting error alerts in apps is essential to communicate failures to your end-users. The happy flow of apps is often implemented well, but the unhappy flow is equally important. Managing all kinds of error alerts can be frustrating if you have to present them all individually. While building my apps, ...

@Published is one of the property wrappers in SwiftUI that allows us to trigger a view redraw whenever changes occur. You can use the wrapper combined with the ObservableObject protocol, but you can also use it within regular classes. It's essential to understand how the published property wrapper works since ...

The @StateObject and @ObservedObject property wrappers tell a SwiftUI view to update in response to changes from an observed object. Both wrappers look similar but have an essential distinction to be aware of when building apps in SwiftUI. At first, you might wonder why you wouldn't just always use @ObservedObject ...

The redacted view modifier in SwiftUI allows us to create a so-called skeleton view while our data is loading. Using a skeleton view instead of a spinner lets the user get a sense of how our views will look once the data is loaded. The user experience is smoother and ...

@EnvironmentObject is part of the family of SwiftUI Property Wrappers that can make working with SwiftUI views a little easier. Sharing data between views can be challenging when working in SwiftUI, especially when we have a lot of child views being dependent on the same piece of data. We could ...
