Eul 是一款简洁、纯粹的 SwiftUI 教程 App，有以下独特之处： 1. 基于最新的 SwiftUI 构建，支持 iOS、iPadOS、macOS 多个平台，教程内容同步更新至最新的 SwiftUI。内容不仅保持最新，也非常全面细致，包括但不限于 SwiftUI、Swift、Concurrency、Combine 等。 2. 与书籍或网站的传统教程不同，Eul 率先提供了一种交互式的学习体验，读者看到的不仅是图文和代码，还能直接在苹果的设备上（iPhone、iPad、Mac）看到代码的真机运行效果。配合深入浅出的文章讲解，这有助于读者更快更好地理解和使用 SwiftUI。 示例附带的源码直接 copy 后就可以在 Xcode 中预览和运行，copy 的代码和示例背后的源码是完全一致的。 3. Eul 还提供了强大的搜索功能，它不仅是一本教程，还可以作为工具书供开发者随时查阅 SwiftUI 的相关知识及使用。 读者如有 iOS 开发经验，可直接开始学习。若是初学者，建议先去熟悉 Swift 语法。 笔者意在尽可能使用简洁明了的语言阐述 SwiftUI 的相关知识，使读者能快速掌握并在 iOS 开发中实践。读者若能从中获益，笔者深感欣慰。如有漏误之处，恳请斧正，不甚感激。 # 联系方式 Email：zzzwco@outlook.com Twitter：zzzwco
