好的，我们继续解读 AppState.swift 文件。

如果说 AppDelegate 是应用程序的“事件总管”，那么 AppState 就是整个应用程序的**“大脑”和“中央数据中心”**。它持有并管理着 app 运行所需的所有状态、数据和核心逻辑。AppDelegate 负责响应系统事件，然后通知 AppState 来进行实际的状态更新和处理。

我没有swift开发经验。请尽可能详细地解释上述代码。

gemini answer

好的，我们来详细解释一下这段 Swift 代码。假设你没有任何 Swift 开发经验，我会用最通俗易懂的方式来讲解。

这段代码定义了一个名为 “Ice” 的 macOS 应用程序的 AppDelegate。你可以把 AppDelegate 想象成这个应用程序的**“总管”或“事件经理”**。当 app 的生命周期中发生关键事件时，比如 app 启动、关闭窗口、或者即将退出时，操作系统就会通知这个“总管”，由它来负责处理。

核心功能总结

简单来说，这段代码为 “Ice” 这个 app 定义了启动时的核心行为。它的主要工作包括：

1. 启动与初始化：处理 app 启动时的一系列设置流程。
2. 权限检查：检查 app 是否获得了正常运行所必需的系统权限。如果没有，它会主动弹出窗口，引导用户去授权。
3. 窗口管理：控制设置窗口和其他窗口的显示与隐藏。
4. 后台运行：确保即使用户关闭了所有可见窗口，app 依然能在后台持续运行。这通常是菜单栏工具的典型特征。

@MainActor is a Swift attribute that ensures code runs on the main thread/main actor. It’s used to guarantee UI updates and other main-thread-only operations execute safely.

Key uses:

• Classes/structs that update UI
• Properties/methods that must run on main thread
• Preventing data races in concurrent code
• SwiftUI view models and UI-related code

上文用的litellm 配置豆包 1.6 使用claude code, 实际体验并不好。
新找了个开源项目效果还不错。

阅读全文 »

​
claudeCode 搞账号太难了。而且挺贵。
目前有白嫖的方式： https://anyrouter.top/register?aff=wWte
注册完，点击右上角的使用指南就可以了。
关键是配置环境变量：ANTHROPIC_AUTH_TOKEN 和 ANTHROPIC_BASE_URL

另外最近kimi开源的k2也可以这么搞。ANTHROPIC_BASE_URL填https://api.moonshot.cn/anthropic,ANTHROPIC_AUTH_TOKEN 填kimi的key就行。

豆包是openapi接口模型，麻烦点，要借助LiteLLM

概述

豆包1.6（Doubao-1.6）是字节跳动最新推出的通用大语言模型，具备强大的代码理解和生成能力。通过 LiteLLM 这个统一的 LLM API 框架，我们可以将豆包1.6 集成到 Claude Code 中，获得更优质的编程辅助体验。

为什么选择豆包1.6 + Claude Code

• 成本优势：豆包1.6 的定价相比 Claude 3.5 Sonnet 更具性价比
• 中文优化：对中文代码注释和技术文档的理解更准确
• 代码能力：在代码生成、重构、解释方面表现出色
• 稳定服务：依托火山引擎，提供企业级稳定性保障

前置条件

1. 已安装 Claude Code CLI 工具
2. 拥有火山引擎账号并完成实名认证
3. 开通了方舟大模型服务

步骤一：获取豆包 API 凭证

1.1 创建 API Key

1. 登录 https://console.volcengine.com/
2. 进入「方舟大模型服务」-「API Key 管理」
3. 点击「创建 API Key」，保存好生成的密钥

1.2 确认模型可用性

在控制台确认已开通 doubao-1-6 系列模型：

• doubao-1-6-chat-32k：通用对话模型
• doubao-1-6-pro-32k：高性能版本
• doubao-1-6-lite-32k：轻量快速版本

在云原生和容器化的世界里，Docker Swarm 为我们提供了一种简单而强大的方式来编排和管理容器集群。然而，在这种便利的背后，是一套复杂而精密的网络模型。当我们兴致勃勃地执行 docker service create 或 docker stack deploy 时，有时会迎面撞上一个令人困惑的错误，就像你遇到的那样：

network sandbox join failed: subnet sandbox join failed for "10.0.3.0/24": error creating vxlan interface: file exists

重启 Docker (systemctl restart docker) 似乎无济于事，但通过 docker stack rm 和 docker network prune 组合拳却能奇迹般地解决。这背后到底发生了什么？

要回答这个问题，我们不能只停留在“怎么解决”的层面，而必须深入底层，从第一性原理（First Principles）出发，理解 Docker Swarm 的网络是如何工作的。
