Ios Swift

What it does

This skill enables AI agents to generate, debug, and explain Swift code specifically for iOS app development. It supports both SwiftUI and UIKit frameworks, assisting with tasks ranging from basic UI creation to complex data persistence using Core Data or SwiftData. The agent can also help configure Xcode project settings and prepare apps for submission via TestFlight.

When to use it

• Creating new iOS applications using Swift and either SwiftUI or UIKit.
• Implementing navigation flows, view controllers, or custom SwiftUI views and modifiers.
• Working with asynchronous operations using async/await or Combine for networking requests (e.g., using URLSession).
• Configuring Xcode project settings related to signing, capabilities, and entitlements.
• Persisting data locally using Core Data, SwiftData, or UserDefaults.

Key capabilities

• SwiftUI view generation and explanation
• ViewModel creation with async/await functionality
• UIKit navigation implementation
• Xcode project configuration (Signing & Capabilities)
• Support for Core Data, SwiftData, and UserDefaults data persistence
• Preparation for App Store submission via TestFlight

Example prompts

• "Generate a SwiftUI view that displays a list of items fetched from a URL."
• "How do I implement navigation between two UIKit view controllers?"
• "Explain the purpose of NSCameraUsageDescription and where to add it in an Xcode project."
• “Create a ViewModel using async/await to load data from this API endpoint: [URL]”

Tips & gotchas

• Remember to perform UI updates on the @MainActor.
• Add necessary privacy keys (like NSCameraUsageDescription) to your Info.plist file before requesting permissions.
• Always test your app thoroughly on real devices and through TestFlight before submitting it to the App Store.
