If you’ve been working with SwiftUI, you’ve likely noticed that your views start pretty simple but then balloon into large, unmaintainable monoliths that are hard to preview and test. While there are several techniques to keep SwiftUI views modular and reusable, some problems are architectural in nature and can only be addressed by following proven ... Read more| Matteo Manferdini
As you create increasingly complex SwiftUI views, you may feel your code is turning into a tangled mess of nested stacks, layout view modifiers, and conditionals. In this article, we’ll explore how to leverage SwiftUI’s full toolkit—beyond just stacks—to build configurable views. You’ll learn to use built-in specialized views, view styles, and view builders for ... Read more| Matteo Manferdini
