Prompting Playbook for Swift

• Specify your minimum deployment target (iOS 17+, iOS 18+) and Swift version (5.9, 6.0) as available APIs and language features differ significantly
• When asking for SwiftUI views, mention whether you need iOS-only or cross-platform (macOS, watchOS) support, as available modifiers and containers differ
• Include your data model (structs/classes with Codable conformance) when asking AI to generate views or network layers that use them
• For async code, specify if you want structured concurrency (TaskGroup, async let) or unstructured (Task { }), and whether strict Sendable checking is enabled
• State whether you prefer MVVM, TCA (The Composable Architecture), or another pattern so the AI generates code matching your architecture

SwiftUI view with async data loading

A SwiftUI list view with async data loading, proper error state handling, and a view model pattern -- a common workflow where AI significantly speeds up iOS development.

import SwiftUI

@Observable
class RecipeListViewModel {
    var recipes: [Recipe] = []
    var isLoading = false
    var error: String?

    private let service: RecipeService

    init(service: RecipeService = .shared) {
        self.service = service
    }

    func loadRecipes() async {
        isLoading = true
        defer { isLoading = false }
        do {
            recipes = try await service.fetchRecipes()
            error = nil
        } catch {
            self.error = error.localizedDescription
        }
    }
}

struct RecipeListView: View {
    @State private var viewModel = RecipeListViewModel()

    var body: some View {
        List(viewModel.recipes) { recipe in
            RecipeRow(recipe: recipe)
        }
        .overlay {
            if viewModel.isLoading {
                ProgressView()
            } else if let error = viewModel.error {
                ContentUnavailableView("Error", systemImage: "exclamationmark.triangle", description: Text(error))
            }
        }
        .task { await viewModel.loadRecipes() }
    }
}
