WWDC26 全部 Session 速览：今年苹果开发者大会都讲了什么

https://developer.apple.com/videos/wwdc2026/今年 WWDC 的 Sessions 今天第一天全部公开了，不再像以前那样分一个星期内每天逐渐发布。

这是一篇「地图式」的 WWDC26 索引：我让 AI把 developer.apple.com/videos/wwdc2026 (https://developer.apple.com/videos/wwdc2026/) 上全部 114 个正式 Session + 20 个 Group Lab 按主题分好类，每条都带一句话说明和直达链接。

怎么用：先看下面的「今年主线」抓住大方向，再用文末的「按目标选片」决定先看哪几个；中间的分类清单当作目录，想深入哪块直接点进去。所有链接都指向 Apple 官方视频页。

今年主线：三句话看懂 WWDC26

• AI 全面下沉到「框架级」。
   今年最大的变化是 Apple 把端侧 AI 拆成了清晰的两层：底层全新的 Core AI（模型转换、编译、在 CPU/GPU/ANE 上跑推理）+ 上层 Foundation Models 框架的大扩展（新增视觉能力、Private Cloud Compute、可接第三方 LLM、Evaluations 评测、agentic/工具调用）。配合 MLX 在 Mac 上跑本地 agent，端侧 AI 第一次有了完整工具链。
• 「Agent」从概念变成开发日常。
   Xcode 内置编码 agent（写原型、翻译本地化、移植游戏），Instruments 能 profile agentic 体验，App Intents / App Schemas 让你的 App 被 Siri 和 Apple Intelligence「调用」，还专门有 Session 讲怎么给 agentic 功能做安全防护和评测。
• 平台各自迭代。
   visionOS 27、Safari 27 / WebKit、Swift 6.3/6.4、SwiftUI 新一轮 API、Xcode 27，外加 Cyberpunk 2077 登 Mac 带来的游戏移植专题。

下面这张图是今年全部内容的「密度地图」——AI 一骑绝尘，SwiftUI、visionOS、开发者工具紧随其后，可以据此判断今年苹果把资源压在了哪：
