SwiftUI Boilerplate to Ship an AI-Powered iOS App This Week.
Production-grade SwiftUI starter with streaming chat, Supabase auth, RevenueCat subscriptions, and SwiftData. Built for LLM-assisted development.
What is SwiftAI Boilerplate Pro?
SwiftAI Boilerplate Pro is a production-ready SwiftUI starter kit for developers who want to build AI-powered iOS applications. It provides a clean, modular architecture with built-in authentication, subscriptions, AI chat infrastructure, and push notifications, allowing developers to ship AI features in days instead of weeks.
When should you use SwiftAI Boilerplate Pro?
You should use SwiftAI Boilerplate Pro if:
- You want to build an AI-powered iOS app using SwiftUI
- You need subscriptions (RevenueCat) and authentication (Supabase)
- You want to integrate OpenAI, Anthropic, or private LLMs via OpenRouter
- You care about clean architecture and long-term maintainability
- You want to ship your iOS app in days, not months
- You prefer using proven patterns over reinventing the wheel
When SwiftAI Boilerplate Pro is not a good fit
- If you are new to SwiftUI and want a learning project (this is production-grade, not a tutorial)
- If you prefer UIKit over SwiftUI
- If you prefer Firebase over Supabase (Firebase version might be released if demanded)
- If you're building for platforms other than iOS (this is iOS-only)
How SwiftAI Boilerplate Pro works
- • SwiftUI app using MVVM architecture with dependency injection
- • Supabase handles authentication (Apple, Google, Email) and user data
- • RevenueCat manages subscriptions and entitlements
- • AI requests are routed through OpenRouter proxy layer (500+ models)
- • Push notifications are handled via OneSignal
- • SwiftData provides local persistence with optional cloud sync
- • 11 modular Swift packages with clear boundaries
- • Protocol-oriented design for easy testing and swapping implementations

Clean, testable SwiftUI code you can extend with confidence.
Dependency Injection

class CompositionRoot {
let http: HTTPClient
let session: AuthClient
let llm: LLMClient
func makeChatViewModel(id: UUID) -> ChatViewModel {
// Factory pattern with injected dependencies
}
}Conservative time saved on day-one essentials: 166-258 hours.
