Mastering SwiftUI Previews: How the Project Structure can hel
summary
Argues that reorganizing code into Swift packages and small, composable views plus separating data and logic yields much faster, reliable SwiftUI previews: preview builds shrink, previews avoid real API or DB access by injecting mocks instead of API calls, and Xcode 15 surfaces preview errors more clearly. Describes a custom per-view, Redux-like state pattern with optional injected logic, shows examples of previewing all dynamic type and color-scheme variants, and reports this approach reduces iteration time and catches edge states.
