When to use this skill

Use this skill whenever the user wants to:

Create iOS applications using Swift with SwiftUI or UIKit
Implement navigation, view controllers, or SwiftUI views and modifiers
Use async/await, Combine, or URLSession for networking
Configure Xcode project settings, signing, capabilities, or entitlements
Persist data with Core Data, SwiftData, or UserDefaults
Prepare for App Store submission via TestFlight

How to use this skill

1. SwiftUI View

struct ContentView: View {
    @StateObject private var viewModel = ItemViewModel()

    var body: some View {
        NavigationStack {
            List(viewModel.items) { item in
                NavigationLink(item.name) {
                    DetailView(item: item)
                }
            }
            .navigationTitle("Items")
            .task { await viewModel.loadItems() }
        }
    }
}

2. ViewModel with async/await

@MainActor
class ItemViewModel: ObservableObject {
    @Published var items: [Item] = []

    func loadItems() async {
        let (data, _) = try await URLSession.shared.data(from: url)
        items = try JSONDecoder().decode([Item].self, from: data)
    }
}

3. Navigation (UIKit)

let detailVC = DetailViewController()
detailVC.item = selectedItem
navigationController?.pushViewController(detailVC, animated: true)

4. Xcode Configuration

Set Signing & Capabilities: Team, Bundle ID, provisioning profile.
Add capabilities (Push Notifications, Background Modes) in the Signing tab.
Archive and upload via Product -> Archive -> Distribute App.

Best Practices

Perform all UI updates on @MainActor; use [weak self] in closures to avoid retain cycles.
Add NSCameraUsageDescription and other privacy keys to Info.plist before requesting permissions.
Test on real devices and via TestFlight before App Store submission.
Follow Apple Human Interface Guidelines for layout, typography, and navigation patterns.
