FAQPage Schema

What is the best Swift architecture pattern for a SwiftUI app?▼

SwiftUI architecture patterns range from MVVM to MVI and TCA, with selection depending on feature complexity and state management needs. Evaluate module boundaries and team requirements to identify the most suitable pattern for your app.

How do I migrate a UIKit app to a new Swift architecture pattern?▼

Migrating a UIKit app to a new Swift architecture requires planning gradual module-boundary changes and evaluating pattern compatibility. Plan migration paths by assessing feature complexity and aligning best practices for modernization without rewriting the entire app.

When should I use TCA over MVVM in Swift?▼

Use TCA over MVVM in Swift when your app requires strict unidirectional data flow and complex state management. TCA is suited for highly complex features, whereas MVVM is often sufficient for simpler SwiftUI views with less state logic.

Does the VIPER pattern work well with SwiftUI?▼

The VIPER pattern can work with SwiftUI, though its heavy module separation is often more natural for UIKit. Evaluate VIPER's compatibility with SwiftUI by assessing your specific feature complexity and whether the Coordinator pattern fits your navigation needs.

How do I choose between Clean Architecture and MVI for Swift?▼

Choosing between Clean Architecture and MVI for Swift involves evaluating feature complexity and module boundaries. Clean Architecture provides broad layer separation, while MVI offers strict unidirectional state management, with the best choice depending on your team's specific needs.

What are the limitations of using the Coordinator pattern in SwiftUI?▼

Limitations of the Coordinator pattern in SwiftUI include potential friction with SwiftUI's native NavigationStack and declarative navigation flow. Consider these constraints during architecture reviews to determine if a Coordinator fits your specific module boundaries and feature complexity.
