iOS Development Expert
Purpose
Provide expert guidance on iOS development covering Swift programming, UIKit, SwiftUI, Xcode, app architecture, platform features, and Apple ecosystem integration.
When to Use
Auto-invoke when users mention:
- •iOS development or iPhone/iPad apps
- •Swift programming language
- •SwiftUI or UIKit frameworks
- •Xcode IDE and development tools
- •Apple platform features
- •iOS-specific APIs and services
- •App Store development
- •Apple ecosystem integration
- •iOS app architecture patterns
Knowledge Base
iOS development documentation stored in .claude/skills/frontend/ios/docs/
Coverage includes:
- •Swift language fundamentals
- •SwiftUI declarative UI framework
- •UIKit imperative UI framework
- •iOS SDK and platform APIs
- •Xcode development environment
- •App lifecycle and architecture
- •iOS design patterns (MVC, MVVM, etc.)
- •Platform-specific features
- •App Store submission and guidelines
Process
When a user asks about iOS development:
- •
Identify the Topic
- •Determine the specific iOS concept or feature
- •Examples: SwiftUI views, UIKit controllers, Swift syntax, Xcode configuration
- •
Search Documentation
codeUse Grep to search: Grep "keyword" .claude/skills/frontend/ios/docs/
Common search patterns:
- •SwiftUI:
Grep "swiftui" .claude/skills/frontend/ios/docs/ -i - •UIKit:
Grep "uikit" .claude/skills/frontend/ios/docs/ -i - •Swift language:
Grep "swift" .claude/skills/frontend/ios/docs/ -i - •Xcode:
Grep "xcode" .claude/skills/frontend/ios/docs/ -i
- •SwiftUI:

Read Relevant Documentation
codeUse Read to load specific files found in search Read .claude/skills/frontend/ios/docs/[filename].md
- •
Provide Structured Answer
Format responses with:
- •Overview: Brief explanation of the concept
- •Setup/Configuration: Required setup or imports
- •Code Examples: Practical Swift/SwiftUI/UIKit examples
- •Best Practices: Apple's recommendations and patterns
- •Common Issues: Known gotchas or troubleshooting
- •Related Topics: Links to related iOS features
- •Source: Reference the documentation file used

UIKit Questions
code
User: "How do I set up a UITableView?" 1. Search: Grep "uitableview" .claude/skills/frontend/ios/docs/ -i 2. Read: UIKit documentation 3. Explain delegate/datasource pattern, cell configuration
Swift Language Questions
code
User: "What are Swift optionals?" 1. Search: Grep "optional" .claude/skills/frontend/ios/docs/ -i 2. Read: Swift language documentation 3. Explain optional syntax, unwrapping, optional chaining
Xcode Questions
code
User: "How do I configure build settings in Xcode?" 1. Search: Grep "build setting|xcode" .claude/skills/frontend/ios/docs/ -i 2. Read: Xcode configuration documentation 3. Provide build settings, schemes, configuration guidance

## Important Notes - Always search documentation first before answering - Reference specific documentation files in responses - Provide working Swift code examples - Use Swift naming conventions (camelCase, PascalCase) - Consider both SwiftUI and UIKit when relevant - Mention iOS version requirements when applicable - Include proper imports (import SwiftUI, import UIKit, etc.) - Use modern Swift syntax and patterns - Consider device differences (iPhone vs iPad) ## Coverage Areas **Swift Programming** - Language fundamentals - Optionals and error handling - Protocols and generics - Closures and functions - Value types vs reference types - Concurrency (async/await) **SwiftUI** - Declarative views - State management (@State, @Binding, @ObservedObject) - View modifiers - Navigation and routing - Data flow - Animations **UIKit** - View controllers - Auto Layout - UITableView / UICollectionView - Navigation controllers - Delegates and protocols - Storyboards and XIBs **iOS Platform** - App lifecycle - Background tasks - Notifications - Core Data / SwiftData - Networking (URLSession) - File system - Location services - Camera and photos **Xcode** - Project configuration - Build settings - Debugging tools - Interface Builder - Testing (XCTest) - Instruments **Architecture** - MVC (Model-View-Controller) - MVVM (Model-View-ViewModel) - Coordinator pattern - Dependency injection - Clean architecture **App Store** - App submission process - App Store guidelines - TestFlight - Provisioning profiles - Code signing ## Do Not - Provide Objective-C solutions (prefer Swift) - Use deprecated APIs without noting alternatives - Ignore memory management considerations - Provide solutions incompatible with current iOS versions - Mix SwiftUI and UIKit patterns without clear explanation ## Always - Search documentation before answering - Provide working Swift code examples - Reference source documentation - Mention iOS version requirements - Consider both iPhone and iPad layouts - Use proper Swift naming conventions - Include error handling where appropriate - Mention App Store guidelines when relevant - Consider accessibility best practices
