Five SwiftUI workflow practices to consider

The code blocks are educational examples, not a verified production package. Check dependencies, platform compatibility and behavior in your own project.

The following are practices to consider for a SwiftUI project. Their usefulness depends on your app; no speed improvement is established here. The code fragments are illustrative and require the app-specific types and dependencies they reference.

1. Component Library First

Start with the reusable components your current screens actually need, for example:

• Custom buttons with loading states
• Reusable card views
• Navigation patterns
• Form components with validation

Keep a component shared when its behavior is genuinely shared; avoid adding an abstraction only to fill a library.

2. Preview-Driven Development

Use previews to inspect a view under relevant states and environments:

#Preview {
    ContentView()
        .environment(\.colorScheme, .dark)
}

A preview can help you discuss the intended UI before adding more behavior.

3. State Management Rules

Choose state wrappers for the observation model and deployment target used by your project. @StateObject and @EnvironmentObject belong to ObservableObject-based patterns; an @observable model uses a different set of ownership and access patterns. Document where state is owned and shared rather than selecting a wrapper by whether a value looks “complex.”

4. MVVM Without Overthinking

Keep ViewModels simple:

@MainActor
@Observable
class ProfileViewModel {
    var user: User?
    var isLoading = false

    func loadUser() async {
        isLoading = true
        user = try? await api.fetchUser()
        isLoading = false
    }
}

No need for complex architectures when starting out.

5. Testing What Matters

Select tests around the behavior and risks of the feature, for example:

• Business logic in ViewModels
• Network response parsing
• Navigation flows

Include UI behavior and accessibility checks when they address a meaningful risk. A changing layout is not by itself a reason to omit verification.

In the view-model sketch, User and api are app-specific placeholders. A complete implementation also needs error, cancellation and overlapping-request handling appropriate to the feature.
