Modern Swift 5.9+ - async/await throughout, structured concurrency with Task and TaskGroup, actors for thread-safe state, Result type for typed errors, property wrappers (@State, @Binding, @ObservedObject) where they earn their keep. 8 style presets (SwiftUI app / UIKit ViewController / SwiftData persistence / Combine pipeline / Vapor server-side / async/await library / Swift Package Manager / XCTest). Generates Package.swift snippet when third-party libs are added.
Yes - a SwiftUI screen + view model + tests costs ~1,800 tokens on Qwen 3 Coder, inside the 2,500 anonymous / 10,000 signed-up daily pool. Premium Claude Sonnet / GPT-5 are particularly worth it for Swift - Apple platform code is one of the higher-difficulty domains and quality jumps noticeably.
Apple has not shipped first-party AI for Xcode beyond predictive completion in Xcode 16. GitHub Copilot ($10-39/mo) works in Xcode via the official extension. Cursor ($20/mo) cannot edit .xcodeproj files but handles Swift code well. Tabnine ($12/mo Dev) supports Swift. Our tool is web-based one-shot - describe a feature, get a complete file.
Pick the SwiftUI app preset. Output is View structs with proper @State / @Binding / @StateObject usage, view modifiers in conventional order (frame, padding, background, tap, animation), .task for async work tied to view lifetime, NavigationStack / NavigationLink for iOS 16+ navigation. Previews via #Preview macro.
Pick the UIKit ViewController preset. Output uses programmatic Auto Layout (NSLayoutConstraint.activate with anchors), proper view lifecycle (loadView vs viewDidLoad vs viewWillAppear), diffable data sources for table/collection views, modern target/action with Selector. iOS 15+ minimum unless you specify older.
Pick the SwiftData persistence preset. Output uses @Model classes, ModelContainer + ModelContext setup, @Query for reactive fetches, predicate macros for type-safe filtering, proper async save/delete via the context. iOS 17+ minimum (SwiftData requirement). For Core Data instead, mention it in your description.
Yes - async/await over completion handlers, throws for error propagation, Result type only where typed errors need to flow through API boundaries. AsyncSequence / AsyncStream for streams. Sendable conformance where actors and concurrency are involved. Strict concurrency checking-friendly.
Pick the Combine pipeline preset. Output uses Publishers properly chained with .map / .filter / .flatMap, .sink stored in cancellables, .receive(on: DispatchQueue.main) where UI updates occur. For new code the SwiftUI + async/await preset is usually a better choice.
Pick the Vapor server-side preset. Output uses Vapor 4 routes, async-await handlers, FluentKit for ORM, JWT middleware for auth, proper Codable models with @ID UUID primary keys. Includes the Package.swift dependency declaration for Vapor.
Pick the XCTest preset. Output uses XCTestCase subclasses, async test methods, proper setUp / tearDown lifecycle, XCTAssertEqual / XCTAssertThrowsError matchers. For Swift Testing (the new framework added in Xcode 16) mention it in your description.
Review every output, especially around App Store rejection risks (private API usage, missing usage descriptions for tracking / camera / location). Apple is strict - the model knows the public API surface but does not know your Info.plist or entitlement file. Run /code/review/ with security focus before merging.
Yes - POST to /v1/chat/ with the same system prompt this page builds. Useful for Xcode templates, fastlane workflows, or scaffolding CLIs. Bearer auth, rate-limited. Docs at /api/.
