A look at FocusState — the new property wrapper introduced with iOS 15 — Managing focus is an important aspect for almost any sort of UI — getting this right helps your users navigate your app faster and more efficiently. In desktop UIs, we have come to expect being able to navigate through the input fields on a form by pressing the tab key…

Learn how to use async/await in SwiftUI apps — Without a doubt, one of the biggest announcements at WWDC21 was Swift Concurrency — most notably the support for async/await. As developers, we’re constantly faced with the asynchronous nature of the apps we write. Reading a file from disk, fetching data from a remote API on the web, and even…

Perform networking calls using reactive programming — Not keeping the UI up to date across the different parts of an app can result in an infuriatingly bad user experience, and I am sure we all have at least one or two apps in mind that are notorious for this kind of behaviour. Writing apps that keep the…

Create meaningful empty states — Empty state is an important aspect of UX — it’s what users see when they first open your app, and as the saying goes, there is no second chance to leave a first impression — so it better be good. …

Replicating Apple’s Reminders app — In our apps, we often need users to confirm an action they initiated, mostly because it’s a destructive operation. …

SwiftUI makes it particularly easy to build list views; it just takes three lines to create a simple list! At the…

Cancelling tasks just got a whole lot easier — Swift’s new concurrency features make it much easier to write correct concurrent code. This is achieved in a number of ways, most prominently by adding features like async/await to the Swift language itself, allowing the compiler to perform flow analysis and providing meaningful feedback to the developer. As Doug points…
