This is the exact prompt I use before building any app infrastructure. 1. THE MASTER INFRA PROMPT You are an expert iOS app developer who has built 10 apps making $80K /yr. You understand modern app architecture, clean code patterns, and scalable infrastructure. I’m building an iOS app and need you to help me set up the infrastructure correctly from day one. Here’s what I need: TECH STACK REQUIREMENTS: • Swift/SwiftUI for iOS • Firebase for backend (Auth, Firestore, Analytics, Crashlytics) • RevenueCat for subscriptions/payments • Superwall for paywall management • Clean MVVM architecture • Async/await for all network calls • Proper error handling • Logging system • Unit test setup APP STRUCTURE: Create a scalable folder structure with: • Models (data models with Codable) • Views (SwiftUI views) • ViewModels (ObservableObject classes) • Services (API, Auth, Analytics, etc.) • Utilities (extensions, helpers) • Resources (assets, strings) KEY SERVICES TO IMPLEMENT: 1. AuthService - Firebase Auth with email/password and social login 2. DatabaseService - Firestore operations with proper error handling 3. AnalyticsService - Firebase Analytics custom events 4. SubscriptionService - RevenueCat integration 5. PaywallService - Superwall integration 6. UserService - user data management 7. NetworkService - API calls with retry logic CRITICAL REQUIREMENTS: • All services should be singletons with dependency injection • Implement proper loading states and error handling • Add analytics tracking for all user actions • Set up crash reporting from day one • Make everything testable with protocols • Use @StateObject and @ObservedObject correctly • Implement proper onboarding flow • Add deep linking support • Set up push notifications infrastructure MONETIZATION SETUP: • Hard paywall after onboarding • RevenueCat products configuration • Superwall paywall triggers • Free trial handling • Restoration purchases • Receipt validation ANALYTICS EVENTS TO TRACK: • App opens, screen views • Onboarding completion rate • Paywall shown/dismissed/converted • Feature usage • Subscription events • Crashes and errors CODE PATTERNS: • Use async/await everywhere • Proper error types with localized messages • Loading states for all async operations • Offline support where possible • Memory management (weak self, etc.) • SwiftUI best practices DEPLOYMENT SETUP: • Xcode project configuration • Bundle IDs and certificates • Firebase project setup • RevenueCat dashboard configuration • TestFlight beta testing • App Store Connect preparation When I describe my app idea, generate the complete infrastructure code including: 1. Project structure with all folders 2. All service classes with full implementation 3. Base ViewModels and Views 4. AppDelegate/SceneDelegate setup 5. Info.plist configuration 6. Package.swift dependencies 7. Firebase configuration files 8. Example usage in main app flow Make everything production-ready, not a tutorial. Include real error handling, proper logging, and scalable patterns I can build on. No shortcuts.

IoC & DI - simple explanation 🧵 IoC (Inversion of Control): You don’t create objects anymore. The framework does it for you. DI (Dependency Injection): Instead of creating dependencies inside a class, they are given to the class. Example: ❌ new DatabaseService() ✅ Framework injects DatabaseService IoC = principle DI = implementation This is why NestJS code is clean, testable, and scalable.

Here's why get_it ended my constructor nightmares: You know that moment when your app grows and you're passing DatabaseService through 6 constructor params just to use it in one button? Yeah, that's where most Flutter apps break. Thread 🧵 (1/5)

Singleton Pattern: • Ensures a class has only one instance. • Example: NetworkService, DatabaseService

Yes, we will need engineer. In personal experience, I found AI write much more code. Sometimes redundant code (like adding a watch to the vue store to update the list, while this already done by other code). Sometimes instead of extends current object (like databaseService), it create another object (like databaseConnector), which will confuse themselves in the future. I just stay there an prompt exactly the plan in my mind. In large code base, maintain it concise and correctness require engineer.

How to integrate Prisma in a NestJS application. Since DatabaseService extends PrismaClient, any class that injects this service can access Prisma's database querying methods directly.

אני לא מסכימה, כי אתה לא באמת יכול לקרוא לדברים FeatureFlagSystem, DatabaseService (בשביל איזו מערכת?) וכו׳. בסוף תקבל או קיצורים או שמות ייעודיים, זה גם חלק מהתרבות של החברה. אם יש תיעוד מינימלי על מה המערכת עושה, זה גם מקל למצוא את כל הדברים הרלוונטיים בקודבייס.

El uso de una instancia de #MySQL #DatabaseService en #OCI como réplica asincrónica es muy útil. Permite probar el servicio con datos siempre actualizados de #onpremise producción: oal.lu/NGa5E Oracle,#OracleCloudInfrastructure,Developers

class Sell {   Sell(CreditService C, DatabaseService D) { … }   boolean apply(Request R) {     if (C.deduct(R.user, R.price)) {       if (D.remove(R.goods)) {         return true;       }     }     return false;   } }

مشکل تست این تابع این‌جاست که نیاز به دو سرویس CreditService و DatabaseService و پایگاه‌داده‌های پشت آن‌ها داریم. تازه فرض کنید، این‌ها خود ممکن است به سرویس‌های دیگر وابسته باشند. چطور می‌توان این تابع را تست واحد کرد؟ یک روش معمول «تزریق وابستگی‌ها»ست (dependency injection): //

یک مثال: فرض کنید واحدی در کدمان داریم برای پردازش درخواست خرید که دو کار انجام می‌دهد: کم‌کردن قیمت کالا از اعتبار خریدار و تغییر پایگاه‌داده انبار. مثلا این واحد، کلاسی به‌شکل زیر است (شبه‌کد) که در آن CreditService و DatabaseService مجموعه‌ای از توابع ساکن (static) اند: //
