Fatbobman's Swift Weekly #088
WWDC 2025 Developer Special EditionWWDC 2025 introduced a host of eye-catching new features and APIs. In this special issue, we’ve handpicked high-value analysis articles, practical tools, and key takeaways from the developer community to help you quickly master the essentials of these new capabilities. Content will continue to be updated through the end of the week. Previous Issue｜Newsletter Archive If you appreciate my work and want to promote your product to the Swift and iOS developer community, sponsoring my blog & newsletter could be an excellent opportunity for you. Featured ResourcesLeveraging large-language models, you can search past WWDC content (including WWDC 25) in natural language. For example, asking “Can the App Intents code now live in an SPM package?” not only returns a clear answer but also provides the corresponding session video for reference. Community-maintained, detailed write-ups of WWDC sessions (including WWDC 25). Contributions from more developers are welcome—see the contribution guide. Apple Developer YouTube Channel If WWDC session videos in the Developer app stutter or lag, you can watch them directly on Apple’s official YouTube channel. WWDC 2025 First Impressions: As Expected, Yet Unexpected by Fatbobman WWDC 2025 arrived right on schedule. Apple released all session videos at once, allowing developers to dive into the new features and APIs they care about without delay. After skimming through them over the past two days, my initial takeaway for this year’s conference is: as expected, yet unexpected. Updates to Apple’s On-Device and Server Foundation Language Models Apple’s official deep dive into the Foundation Models framework. It thoroughly showcases the core models, optimization strategies, and paths for developer support behind Apple Intelligence—highlighting not just improvements in inference efficiency and model capability, but also systematic designs for privacy, controllable outputs, and multilingual support. All New Frameworks Presented at WWDC 25 by Marco Eidinger A comprehensive roundup of the new frameworks unveiled at WWDC 2025. You can also browse all official Apple frameworks here. Opting Your App Out of the Liquid Glass Redesign with Xcode 26 by Donny Wals Not ready to adapt to Liquid Glass? Apple gives developers a one-year grace period, allowing apps to continue using the traditional UI style on iOS 26 by disabling Liquid Glass. Setting Default Actor Isolation in Xcode 26 by Donny Wals Xcode 26 introduces many new Swift 6.2 concurrency features. Misconfiguration can lead to compilation failures—this guide shows how to set the default actor isolation correctly. Apple Intelligence APIs by Alex A two-part series that presents every aspect of the Foundation Models on offer. See both parts here. What’s New with SwiftUI 26 by Thomas Ricouard and What Is New in SwiftUI after WWDC 25 by Majid Jabrayilov Quick overviews of SwiftUI’s new features compiled by Thomas Ricouard and Majid Jabrayilov. iOS 26: Notable UIKit Additions by Jordan Morgan Key new capabilities brought to UIKit in WWDC 2025. How to Observe Model Changes in iOS 26 by Khoa UIKit views gain the same automatic Observable response as SwiftUI—this article walks through how to use it. WebView Is Finally Coming to SwiftUI by Daniel Saidi A guide to using the new native WebView in SwiftUI. Create Immersive Backgrounds in SwiftUI with backgroundExensionEffect by Natalia Panferova The Discussion on Flutter’s Support for Liquid Glass The Flutter team prefers modular, community-driven design styles rather than chasing every native UI update. To achieve Liquid Glass effects in Flutter, you’ll need third-party packages or custom components for now. Virtualizing macOS 26 Tahoe by Howard Oakley A complete guide to safely running the macOS 26 Beta (Tahoe) in a VM on Apple Silicon Macs. A Brief Exploration of Liquid Glass’s Under-the-Hood Implementation by Cyandev Liquid Glass is powered by Apple’s private layering system—combining How to Fix Projects That Won’t Open in Xcode 26 by Cihat Gündüz Right-click the A tool for enabling Apple Intelligence features on macOS 26 in regions where access hasn’t yet been opened. WWDC 2025 开发者特辑WWDC 2025 带来了众多令人瞩目的新功能和 API。作为特刊，本期周报精选了开发者社区颇具价值的解读文章、实用工具和关键注意事项，帮助大家快速掌握新特性的核心要点。内容将持续更新至本周末。 如果您发现这份周报或我的博客对您有所帮助，可以考虑通过 爱发电，Buy Me a Coffee 支持我的创作。 精选资源借助大模型技术，你可以用自然语言搜索历届 WWDC 内容（包括 WWDC 25）。比如询问"App Intents 的代码现在可以放在 SPM 中吗？"，不仅会给出明确答复，还会附上相应的 Session 视频作为参考。 社区维护的 WWDC Session 详细记录（包含 WWDC 25）。欢迎更多开发者参与贡献。 当 Developer 应用中的 WWDC Session 视频播放卡顿时，可直接访问苹果在 YouTube 上的官方频道观看。 WWDC 2025 初印象：意料之中，预想之外 by Fatbobman WWDC 2025 如期而至。苹果一次性发布了所有的 Session 视频，让开发者得以在第一时间了解自己感兴趣的新特性和新 API。经过两天的快速浏览，我对本届 WWDC 2025 的初步印象为：意料之中，预想之外。 Updates to Apple's On-Device and Server Foundation Language Models 苹果官方对 Foundation Models 框架的详细介绍。全面展示了 Apple Intelligence 背后的核心模型、优化策略与开发者支持路径。亮点不仅在于推理效率和模型能力的提升，更体现在隐私保护、可控输出和多语言支持的系统性设计上。 All New Frameworks Presented at WWDC25 by Marco Eidinger WWDC 2025 推出的新框架完整汇总。你还可以在此处检索所有苹果官方框架信息。 Opting Your App Out of the Liquid Glass Redesign with Xcode 26 by Donny Wals 暂时没有精力适配 Liquid Glass？苹果为开发者提供了一年缓冲期，允许应用在 iOS 26 系统上继续使用传统 UI 风格（禁用 Liquid Glass）。 Setting Default Actor Isolation in Xcode 26 by Donny Wals Xcode 26 支持了众多 Swift 6.2 新并发功能。如果配置不当，可能导致代码无法编译。 Apple Intelligence APIs by Alex 共两篇文章，全方位展示 Foundation Models 的各个方面。 What’s new with SwiftUI 26 by && What is New in SwiftUI after WWDC25 Thomas Ricouard 和 Majid Jabrayilov 整理的 SwiftUI 新功能速览。 iOS 26: Notable UIKit Additions by Jordan Morgan WWDC 2025 为 UIKit 带来的重要新功能。 How to Observe Model Changes in iOS 26 by Khoa iOS 26 中，UIKit 视图获得了与 SwiftUI 相同的 Observable 自动响应能力，本文详细介绍其使用方法。 WebView is Finally Coming to SwiftUI by Daniel Saidi SwiftUI 原生 WebView 的使用指南。 Create Immersive Backgrounds in SwiftUI with backgroundExtensionEffect by Natalia Panferova
Flutter 团队避免陷入追逐每次原生设计更新的循环，更倾向于让设计风格模块化、社区化。如果希望在 Flutter 中实现 Liquid Glass 风格，短期内需依赖第三方包或自定义组件。 Virtualising macOS 26 Tahoe by Howard Oakley 在 Apple Silicon Mac 上安全运行 macOS 26 Beta（Tahoe）虚拟机的完整指南。 Liquid Glass 底层实现的简单探索 by Cyandev Liquid Glass 效果主要由苹果内部的私有图层系统实现，核心是 CABackdropLayer 和 CASDFLayer 的组合。它通过一个特殊的 glassBackground 滤镜和动态生成的 SDF 纹理，呈现出折射、融合等玻璃感效果。这些图层被 _UIMultiLayer 封装，开发者无法直接访问，所有动画和参数调节也都由 UIKit 内部完成。 修复项目无法在 Xcode 26 中打开的方法 by Cihat Gündüz 右键点击 .xcodeproj 文件，选择"显示包内容"。对 project.xcworkspace 执行相同操作，删除 xcuserdata 文件夹（包含不兼容的 .xcuserstate 文件）。 在尚未开放 Apple Intelligence 权限的地区，为 macOS 26 开启相关功能的工具。 Welcome to my blog Fatbobman's Swift Blog( 肘子的Swift记事本 )
