iOS (Swift) Patterns

Concise guides for modern Swift/SwiftUI apps.

• Architecture
  • MVVM with ObservableObject
  • Coordinator Navigation
  • Clean Architecture
• Concurrency & Data
  • Async/Await + Result
  • Repository + Codable
• DI & UI
  • Protocol-based DI
  • SwiftUI State management

Try it

Create a new Xcode project: iOS App → SwiftUI + Swift. Then paste the minimal files from a guide into your project:

• Add a new Swift file for the ViewModel (e.g., TodosVM.swift).
• Add a new Swift file for the repository protocol/impl (e.g., TodosRepo.swift).
• Wire the view in ContentView.swift or a new view, and set it in @main App.

Optional CLI helpers

# Open the current folder in Xcode (macOS)
open .

# Format with swift-format if installed
swift-format -i -r .

Tips

• For quick HTTP tests, point to https://jsonplaceholder.typicode.com.
• Use @MainActor on view models that publish UI state.
