Model View Controller Store: Reinventing MVC for SwiftUI with Boutique

Apple has never provided a blessed architecture for SwiftUI, and many developers have spent thousands of hours filling the gaps with their own ideas. A familiar approach for many developers is to take the MVVM pattern many people adopted in their UIKit/AppKit apps and translate it to the needs of SwiftUI. That can work well enough, but you begin to see some cracks in the architecture when you need to manage state and data flow due how heavily SwiftUI leans on having a single source of truth. Others have taken the path of integrating powerful libraries such as The Composable Architecture which provide you with the tools to reason about your entire application. TCA takes inspiration from redux, more specifically The Elm Architecture, two patterns that are rather incredible in how they allow you to define your entire application as a tree of state. But TCA's great power comes with great responsibility a very high learning curve, which can make it difficult to learn personally. TCA's goals are much more of a fit…

Mastering NavigationStack in SwiftUI. Navigator Pattern.

SwiftUI is the declarative data-driven framework allowing us to build complex user interfaces by defining the data rendering on the screen. Navigation was the main pain point of the framework from the very first day. Fortunately, things have changed since WWDC 22, and SwiftUI provides the new data-driven Navigation API. This week we will learn how to use the new Navigation API to build complex user flows.
