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
Use 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
- Read Relevant Documentation
Use 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
Example Workflows
SwiftUI Questions
User: "How do I create a list view in SwiftUI?"
1. Search: Grep "list|swiftui" .claude/skills/frontend/ios/docs/ -i
2. Read: SwiftUI documentation files
3. Answer with SwiftUI List examples, modifiers, data bindingUIKit Questions

1. Search: Grep "uitableview" .claude/skills/frontend/ios/docs/ -i
2. Read: UIKit documentation
3. Explain delegate/datasource pattern, cell configurationSwift Language Questions
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 chainingXcode Questions
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 guidanceResponse Format
Always structure responses as:
## [Topic Name]
[Brief overview paragraph]
### Setup

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)
