About_App 是一个即插即用的“关于”页面。它显示一个带有产品标志和附加信息的单页。它也能正确处理横向旋转。当前的实现使用了 Swift 5.9 Observation 模型，需要 iOS 17 或 macOS 13。

import About_App

创建一个 About 对象的实例。在你稍后可以将其传递到环境中的位置创建它。

let about = About()

设置你想要显示的属性。大多数属性默认为 nil，如果未显式设置，则不会显示。

about.appName = "My App"
about.createdBy = "Ferdinand G. Rios"
about.copyRight = "© 2020, My Company, Inc."
