ios-swift

When to use this skill

Use this skill whenever the user wants to:

• Develop iOS apps with Swift, SwiftUI or UIKit, system frameworks, and App Store release
• Configure Xcode projects, signing, Capabilities, and TestFlight

How to use this skill

1. Project: Xcode, SwiftUI or UIKit; Model-View, Combine/async; navigation and lifecycle.
2. System: URLSession, UserDefaults, Core Data; permissions and background.
3. Reference：https://developer.apple.com/documentation/swift

Best Practices

• Main thread and UI; memory and reference cycles (weak).
• Permission and privacy descriptions; TestFlight and review guidelines before release.

Keywords

iOS, Swift, SwiftUI, UIKit

Capability Boundaries

✅ Applicable Scenarios

• When you need to use the tech stack corresponding to this skill
• When the project needs to follow best practices
• When you need to get started quickly or gain an in-depth understanding of core concepts

⚠️ Points to Note

• Complex business logic needs to be adjusted according to specific scenarios
• Performance optimization needs to be evaluated based on the actual data volume

❌ Inapplicable Scenarios

• Unrelated tech stacks or frameworks
• Special scenarios requiring full customization

Common Pitfalls (Gotchas)

1. Version Compatibility: Pay attention to the compatibility between framework versions and dependency libraries; APIs may differ across versions
2. Configuration File Format: Configuration file format errors are the most common problem; it is recommended to use the editor's syntax checking
3. Environment Variables: Ensure all necessary environment variables are set correctly, and do not hardcode sensitive information
4. Dependency Conflicts: Pay attention to dependency conflicts when multiple versions coexist, and use lock files to pin versions
5. Performance Pitfalls: Pay attention to performance optimization in large-data-volume scenarios, and avoid common problems such as N+1 queries

Usage Flow

Step 1: Environment Preparation

Ensure the necessary dependencies and tools are installed in the development environment.

Step 2: Configuration Initialization

Perform basic configuration according to project requirements.

Step 3: Using Core Features

Implement core features according to the sample code.

Step 4: Testing and Verification

Run tests to ensure the features work properly.

Step 5: Deployment and Release

Perform deployment and monitoring after completing development.
