A clean, testable SwiftUI base that lets you move.

MVVM, CompositionRoot DI, protocol-oriented design, and async/await, with Supabase, RevenueCat, and OpenRouter ready on day one.

Why developers pick it

Testable architecture with view models that have no UIKit dependencies
CompositionRoot dependency injection, no global singletons
Protocol-oriented, easy to mock and swap implementations
Design tokens and themes for consistent UI
Streaming AI via OpenRouter with typed clients

Architecture and testing

Every module follows MVVM with protocol-based dependencies. View models are testable without UIKit. The CompositionRoot handles wiring at startup. Networking, storage, and AI clients are swappable through protocols.

Networking module

protocol NetworkClient {
  func request<T>(...) async throws -> T
}

class ProductionNetworkClient: NetworkClient {
  // Real implementation
}
