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:

1. Identify the Topic

- Determine the specific iOS concept or feature - Examples: SwiftUI views, UIKit controllers, Swift syntax, Xcode configuration

1. 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

1. Read Relevant Documentation Use Read to load specific files found in search Read.claude/skills/frontend/ios/docs/[filename].md
2. 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 binding

UIKit Questions

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

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

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

Response Format

Always structure responses as:

## [Topic Name]

[Brief overview paragraph]

### Setup

[Required imports, configuration, prerequisites]

### Implementation

// Code examples with comments import SwiftUI

struct ContentView: View { var body: some View { Text("Hello, iOS!") } }

### Key Points

- Important concept 1
- Important concept 2
- Important concept 3

### Common Issues

- Issue and solution
- Gotcha and workaround

### Related

- Related feature or concept
- Link to additional documentation

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)
