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.
