Weekly Newsletter Progress and Blog Updates
On the evening of the latest weekly newsletter's release, the email subscription count surpassed 3,000. Combined with other distribution channels, each weekly newsletter now reaches at least 6,000 readers in the week following its publication. While this may not be an extraordinary achievement, it has far exceeded my initial expectations when I started this journey.
The key reason the weekly newsletter has gained such a following is the constant flow of high-quality content from the community. Over the past year, although some excellent authors have reduced their contributions for various reasons, new authors consistently bring fresh, outstanding articles every month. In most issues, I even find myself struggling to choose among so many great pieces—a "happy dilemma" that leaves me deeply gratified.
Of course, reader support is another crucial factor in the newsletter's continued growth. Receiving positive feedback from readers and seeing some articles gain more visibility thanks to recommendations in the newsletter constantly remind me of the value of this work.
Last week, I made a significant adjustment to the blog's architecture, migrating it from the traditional cloud hosting + CDN model to a Serverless setup. This change has greatly simplified the deployment process and reduced deployment time, giving me an opportunity to optimize part of the blog’s code. During this transition, some readers may have experienced issues accessing the blog due to DNS propagation delays. Here are a few potential solutions to resolve this:
Clear your browser cache, especially for data related to the blog.
Configure your device to use a more well-known DNS provider for faster propagation.
Visit the backup site at fatbobman.github.io.
Additionally, I have introduced a new "Quick Tips" section on the blog. This section is dedicated to concise, focused articles that address specific problems. These articles avoid in-depth discussions or theoretical explanations, allowing readers to quickly find practical solutions.
Thank you to every reader for your support and feedback. I look forward to continuing this journey together and witnessing the creation of even more amazing content in the future!

Advanced Navigation Destinations in SwiftUI
Since the introduction of NavigationStack, SwiftUI has significantly enhanced navigation flexibility. However, the native implementations of NavigationPath and navigationDestination still face limitations, particularly the need to define a separate handler for each navigation destination, which often leads to redundant code and maintenance challenges. To address these issues, Michael Long developed an open-source library, Navigator, which provides a more powerful navigation layer for SwiftUI, seamlessly supporting both declarative and imperative navigation. In this article, Long delves into the shortcomings of native navigation approaches and explains how Navigator improves the developer experience with features like enumerated navigation destinations, coordination patterns, and navigation checkpoints, offering an elegant solution for complex navigation needs.
Getting Git Revision Info Within Your iOS App
In the fast-paced development cycle of modern projects, it’s often difficult for developers to pinpoint the exact branch or version when receiving feedback from testers or users. Rich Infante shares a simple yet effective method to address this challenge: by using a build script, you can embed the current Git commit hash and branch name into your app. This enables developers to quickly trace the state of the source code during debugging and version releases, providing a robust tool for version management.
Uncovering and Solving a SwiftUI Text Animation Bug
SwiftUI is widely appreciated for its simplicity in creating animations, but sometimes, even with careful adjustments, views may not behave as expected. In this article, Omar Elsayed shares a problem encountered in a project where the offset animation for a Text view failed to work. By referring to a solution proposed by developer kurtlee93, the issue was resolved using GeometryEffect and AnimatableData.
When animations fail, developers often turn to
AnimatableDatato explicitly provide interpolation for views, which usually yields the desired result. However, we still hope Apple resolves these long-standing bugs soon.
How a New Xcode 16 Feature Helped My Work Project Eliminate 66,000 Lines of Code
Xcode 16 introduced the buildable folders feature, allowing direct file management through the file system and eliminating the need for complex references in pbxproj files. In this article, Makwan Barzan shares how his team’s detailed and effective efforts reduced 66,000 lines of redundant references in their old project’s pbxproj file. By adopting folder-based organization, they not only minimized merge conflicts but also significantly improved project management efficiency.
Building a Weather API Backend with Swift Vapor: A Deep Dive
Many Swift developers have considered trying Vapor for building backend services. Arrinal used SwiftUI and Vapor to create an open-source weather service project. Through two articles, he systematically explains how to apply Clean Architecture principles to build a maintainable and extensible SwiftUI app and provides a backend service to support it. In the frontend section, he demonstrates how dependency injection (Swinject) and Combine enable reactive data flow while maintaining a clear architecture. On the backend, he leverages Vapor’s modern features, such as async/await and middleware, to create a high-performance and standardized API service seamlessly integrated with the SwiftUI app.
SwiftUI Lists: Present Rows of Data Explained with Code Examples
List is a core component in SwiftUI, offering efficient data row presentation and multiple built-in styles to meet various UI needs. However, many developers may not fully understand the differences and use cases for each style. Antoine van der Lee provides a comprehensive guide through intuitive code examples, showcasing the basic functionalities of SwiftUI List, its different styles, and advanced features like grouping, selection, and customized backgrounds. This article serves as a practical and clear resource for developers to master the use of List.

周报进展与博客调整
在上期周报发布的当晚，邮件订阅量突破了 3000。结合其他发布渠道，每期周报在发布当周至少覆盖 6000 名以上的读者。虽然这一成绩谈不上多么卓越，但已远远超出了我创办之初的预期。
周报能够获得如此多读者的喜爱，最重要的原因在于社区中不断涌现的优质内容。过去一年中，虽然一些优秀的作者因种种原因减少了分享，但每个月都会有新的作者带来高质量的文章。在大多数情况下，我甚至会因为精彩文章过多而纠结于取舍，这种“幸福的烦恼”让我倍感欣慰。
当然，读者的支持也是周报持续发展的重要动力。无论是收到读者的正向反馈，还是看到一些作者的文章因周报推荐而获得更多阅读量，都让我感受到这份工作的意义和价值。
上周，我对博客架构进行了重要调整，将其从传统的云主机 + CDN 模式迁移到 Serverless。此举极大地简化了博客的部署流程和耗时，因此我也趁机优化了一部分代码。在此期间，由于 DNS 刷新的延迟问题，部分读者可能遇到页面无法访问的情况。以下是几种可能的解决办法：
清空浏览器的缓存，特别是与博客相关的部分；
将设备的 DNS 设置为更知名的解析服务商，以加快 DNS 刷新；
访问博客的备份站点：fatbobman.github.io。
此外，我在博客中新增了一个“小贴士”板块，用于分享内容简短、主题明确的文章。这类文章聚焦于快速解决实际问题，不涉及原理和讨论，方便读者以最快的方式找到答案。
感谢每一位读者的支持和反馈，期待未来能和大家一同见证更多精彩内容的诞生！

🪜 SwiftUI 高级导航 (Advanced Navigation Destinations in SwiftUI)
SwiftUI 自引入 NavigationStack 后，显著提升了导航的灵活性。然而，NavigationPath 和 navigationDestination 的原生实现在实际使用中仍显局限，尤其是每个导航目标都需单独定义处理器，容易导致代码重复和维护困难。为了解决这些问题，Michael Long 开发了开源库 Navigator，为 SwiftUI 提供了一套功能更加强大的导航层，支持声明式与命令式导航的无缝切换。在这篇文章中，Long 深入探讨了原生导航方式的不足，以及 Navigator 如何通过枚举导航目标、协调模式和导航检查点等特性改进开发体验，为复杂的应用导航需求提供了优雅的解决方案。
在 iOS 应用中获取 Git 修订信息 (Getting Git Revision info within your iOS App)
在项目快速迭代的过程中，当开发者收到测试员或用户的反馈时，往往难以及时定位问题所在的分支或版本。Rich Infante 分享了一个简单且高效的方法：通过构建脚本，将当前代码库的 Git 提交哈希值、分支名称等信息嵌入到应用中，帮助开发者在调试和发布版本时快速追溯源代码的状态。
🪜 SwiftUI 文本动画 Bug 的发现与解决 (Uncovering and Solving a SwiftUI Text Animation Bug)
SwiftUI 因其简洁易用的动画功能而广受开发者喜爱，但有时，即使我们精心调整，视图也未必能按预期实现动画效果。在这篇文章中，Omar Elsayed 分享了他在项目中遇到的一个问题：Text 视图的 offset 动画无法正常工作。通过参考开发者 kurtlee93 提出的解决方案，作者利用 GeometryEffect 和 AnimatableData 成功解决了这一问题。
遇到动画失效的问题时，开发者常用
AnimatableData为视图显式提供动画插值，经常能达到预期效果。不过，我们仍然期待苹果尽快修复这些长期存在的 bug。
Xcode 16 的新特性如何帮助我的项目减少 66,000 行代码 (How a New Xcode 16 Feature Helped My Work Project Eliminate 66,000 Lines of Code)
