SwiftUI Agent Skill

为什么要用

核心特性

iOS 17+ Observation framework (no more ObservableObject in new code)
NavigationStack patterns with type-safe destinations
Common pitfalls list (TextField + State race conditions, sheet vs popover)
Accessibility annotations baked into examples
Test-friendly view structure

安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "swiftui-agent-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ],
      "_inferred": true
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "swiftui-agent-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ],
      "_inferred": true
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "swiftui-agent-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ],
      "_inferred": true
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "swiftui-agent-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ],
      "_inferred": true
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "swiftui-agent-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "swiftui-agent-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/twostraws/SwiftUI-Agent-Skill",
          "~/.claude/skills/SwiftUI-Agent-Skill"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add swiftui-agent-skill -- git clone https://github.com/twostraws/SwiftUI-Agent-Skill ~/.claude/skills/SwiftUI-Agent-Skill

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： SwiftUI Agent Skill

Build a settings screen the right way (iOS 17+)

👤 iOS devs ⏱ ~15 min intermediate

何时使用： You want a Settings screen that's actually idiomatic for iOS 17+.

前置条件

Server/skill installed and authenticated — See repo README

步骤

Plan

Using the SwiftUI skill, design a Settings view with sections: Account, Notifications, About. Use @Observable for the view model.✓ 已复制

→ View hierarchy + ViewModel sketch
Code

Write the full file with toggles, NavigationLink to subpages, and a confirmation dialog for sign-out.✓ 已复制

→ Compiles on Xcode 15+

结果： Idiomatic SwiftUI you don't have to rewrite next year.

注意事项

Don't mix @StateObject with @Observable — Don't mix @StateObject with @Observable — the skill enforces one or the other; follow it.

成本与限制

运行它的成本

API 配额: See provider docs for rate limits
每次调用 Token 数: Varies by tool
费用: See repo README for pricing details
提示: Cache tool results and avoid repeated identical calls.

安全

权限、密钥、影响范围

凭据存储： Use environment variables; never commit secrets

数据出站： Tool calls go to the provider's API as documented

故障排查

常见错误与修复

view doesn't update on state change

Ensure the property is on an @Observable class, not a struct. The skill's checklist covers this.

验证： @Observable annotation present

preview crashes

@Observable views need a real instance in #Preview. The skill's examples show the pattern.

验证： Preview compiles
