My WWDC 2025 viewing guide to help you plan the sessions you want to watch.
我的 WWDC 2025 观看指南，帮助你规划想观看的会议。

Where Do I Start?
我该从哪里开始？

The two big themes for the year are Liquid Glass design and Apple Intelligence. Start by watching the Platforms State of the Union (SOTU) for a summary of what’s new this year.
今年的两个大主题是液态玻璃设计和苹果智能。先观看平台年度大会（SOTU），了解今年的新内容概览。

You don’t have to learn everything new today!
你不必今天就学会所有新东西！

There are over 100 sessions and a lot of new stuff to learn. You may feel like you’re getting left behind. Don’t let it overwhelm you. You’ve got time.
有超过 100 个会议和许多新内容可供学习。你可能会觉得自己被落下了。别让自己感到不知所措。你还有时间。

Don’t burn yourself out trying to keep up.
不要为了跟上进度而透支自己。

Watching The Sessions  观看会议

I watch the videos using the Apple Developer app. It’s available on macOS and iOS. The video player supports from 0.5x to 2x playback, most videos have transcripts, some have summaries, and allow copying of the onscreen sample code. You can also watch on YouTube.
我使用 Apple Developer 应用观看视频。该应用可在 macOS 和 iOS 上使用。视频播放器支持 0.5 倍到 2 倍的播放速度，大多数视频都有文字记录，有些还有摘要，并允许复制屏幕上的示例代码。你也可以在 YouTube 上观看。

There are a lot of sessions, but many are short (10-20 minutes). There’s no padding and Apple’s engineers get to the point quickly.
有很多场次，但许多都很短（10-20 分钟）。没有冗余内容，苹果的工程师们直奔主题。

Swift

Swift 6.2 is here with some updates to ease the pain of adopting Swift Concurrency:

These Swift Concurrency sessions are essential viewing. This seems like a better Concurrency approach:
这些 Swift 并发相关的课程是必看内容。这似乎是一种更好的并发方法：

  • Embracing Swift concurrency Start by running code on the main thread. Introduce concurrency as you need it. Swift 6.2 allows a module to default to main-actor isolation. Use async tasks to await for data. Interleaving - single thread alternating between tasks. Run code on a background thread by marking method with @concurrent. Use nonisolated for library API and let client decide. Actors to move data off main thread. Enable Approachable Concurrency and Default Actor Isolation build settings.
    拥抱 Swift 并发 从在主线程上运行代码开始。根据需要引入并发。Swift 6.2 允许模块默认使用主 actor 隔离。使用异步任务等待数据。交错执行——单线程在任务之间交替运行。通过在方法上标记 @concurrent 在后台线程运行代码。对库 API 使用 nonisolated，让客户端决定。使用 Actors 将数据移出主线程。启用 Approachable Concurrency 和 Default Actor Isolation 构建设置。

  • Code-along: Elevate an app with Swift concurrency Transform a single-threaded app to use concurrency as needed.
    代码实操：用 Swift 并发提升应用 将单线程应用根据需要转换为使用并发。

  • Explore concurrency in SwiftUI SwiftUI views are isolated to the main actor. Tasks in the view run on the main actor. Find the boundaries between your UI code and non-UI code. Default actor isolation setting removes need for most @MainActor annotations.
    探索 SwiftUI 中的并发 SwiftUI 视图被隔离到主 actor。视图中的任务在主 actor 上运行。找到 UI 代码和非 UI 代码之间的边界。默认的 actor 隔离设置消除了大多数 @MainActor 注解的需求。

Interoperability with C, C++, and Java:
与 C、C++ 和 Java 的互操作性：

  • Safely mix C, C++, and Swift Strict memory safety build setting, off by default. Annotate C and C++ functions and types so Swift can use them safely.
    安全混合使用 C、C++ 和 Swift 默认关闭的严格内存安全构建设置。为 C 和 C++ 函数及类型添加注解，使 Swift 能安全使用它们。

  • Explore Swift and Java interoperability Incremental adoption of Swift by mixing Swift and Java code. Calling Swift from Java or vice-versa.
    探索 Swift 与 Java 的互操作性 通过混合 Swift 和 Java 代码，逐步采用 Swift。实现从 Java 调用 Swift 或反之亦然。

  • Meet Containerization Open source Swift framework to create and run Linux containers on macOS.

Design

The Liquid Glass sessions are essential viewing this year:

  • Meet Liquid Glass Liquid Glass lensing bends and shapes light. Adapts to ensure legibility and separate controls from content. Best reserved for navigation layer that floats above content. Do not stack Liquid Glass. Only tint to emphasise primary elements and actions. Reduced Transparency makes Liquid Glass frostier.

  • Get to know the new design system Adjusted System colors for Liquid Glass. Alert Text is left-aligned. Concentricity aligns radii so shapes nest. Larger controls use capsule shapes. Sheets spring from an action source. Remove custom backgrounds from controls. Primary action stays separate and tinted. Hard scroll edge effect on macOS for stronger boundary. Bars rely more on symbols, see HIG for glyphs for common actions.

  • Design foundations from idea to interface Start with app structure. Where am I? What can I do? Where can I go from here? Use toolbar for screen specific actions. Progressive disclosure. Group by time, progress or patterns. Use a cohesive visual style. Design is never really finished.

  • Make a big impact with small writing changes Simplify. Too many filler adverbs and adjectives. Does each word add value. Don’t apologise for errors. Avoid repetition. Lead with the why (move the benefit to the front). Word list to track terms with use/don’t use and definition. Read your writing out loud.

  • Principles of inclusive app design One in seven people have a disability. Vision. Hearing. Motor. Speech. Cognitive. Inclusive design is better for everyone. Involve members of the disability community in your design. Test with VoiceOver and Switch Control.

  • What’s new in SF Symbols 7 Draw path animation inspired by handwriting. Symbol gradients. Annotate custom symbols with path to draw.

  • Say hello to the new look of app icons Liquid glass material layers. Monochrome, light, and dark tint, translucent appearance modes. Rounder corner radius. macOS icons no longer extend outside the shape. Layers & translucency. Use softer light-to-dark gradients for backgrounds. Use System Light and System Dark for white or black backgrounds.

  • Design interactive snippets Compact views displayed from App Intents in Siri, Spotlight, and Shortcuts. Quick, in-moment experiences. Easy to read with larger type, concise, clear contrast. Buttons for interaction. Result and confirmation snippets.

Platform specific sessions:

  • Elevate the design of your iPad app Consider starting with a tab bar. Extend content around navigation. New windowing system with new controls. Apps not yet updated for iOS 26 show controls in safe area. Create a new window for each document. Name your windows. New pointer shape. Menu bar on top edge of iPad.

  • Design widgets for visionOS Three dimensional objects. Compatibility mode for existing iPadOS widgets. Widgets persist in location and are fixed in size. Adapt with user proximity. Paper or glass styles. Elevated or recessed mounting styles.

  • Design hover interactions for visionOS Custom hover effects. Look to scroll. Starts when user looks at edge of scroll view. Opt-in, enable when view is primarily for reading or browsing. Persistent controls stay visible while you look at them.

Accessibility

Machine Learning and Apple Intelligence

An API to access an on-device Large Language Model (LLM) was high on everyone’s wish list:

  • Meet the Foundation Models framework API access to Apple’s LLM. On-device so data stays private and can run offline. Experiment with prompts using the new Playground feature in Xcode. On-device model not intended for world knowledge or advanced reasoning. Adapters for common tasks. Use @Generable and @Guide to define Swift type that models returns. Streams partially generated types. Model can callout to tools you define. Session instructions get priority over user prompts. Context is retained during a session. Only available where Apple Intelligence is available.

  • Deep dive into the Foundation Models framework Session throws error when it reaches available context size. Create new session with extract or summary from previous session to provide context. Greedy sampling produces deterministic output. Check for supported languages. @Generable macro defines structured schema for responses. Constrained decoding forces model to return valid tokens for the schema. String properties can use a regex pattern guide. Tool protocol to define functions model can call to access external data.

  • Explore prompt design & safety for on-device foundation models On-device LLM has ~3-billion parameters, small when compared to cloud based models. May need to break down complex prompts. Avoid maths, code, or tasks requiring real world knowledge. Avoid where facts are critical or provide verified information in prompt.

    Use prompts like “in a few words” or “in detail” to control output. Provide model with a role. Ask a single, detailed task. Less than five examples in prompt. Use “DO NOT”. Apple designed guardrails to block harmful inputs and throw safety errors. Use instructions to steer model output. Never include user input in instructions.
