所以，苹果最终还是自己打了自己 Human Interface Guidelines 的脸…

附上WWDC22期间苹果对HIG里相关内容的暗搓搓改动：

改动前： https://web.archive.org/web/20210428111637/https://developer.apple.com/design/human-interface-guidelines/ios/visual-design/adaptivity-and-layout/

Don’t mask or call special attention to key display features. Don’t attempt to hide a device’s rounded corners, sensor housing, or indicator for accessing the Home screen by placing black bars at the top and bottom of the screen. Don’t use visual adornments like brackets, bezels, shapes, or instructional text to call special attention to these areas, either.

（由iOS翻译App翻译）不要屏蔽或特别注意关键的显示功能。不要试图通过在屏幕顶部和底部放置黑条来隐藏设备的圆角、传感器外壳或用于访问主屏幕的指示器。也不要使用括号、边框、形状或教学文本等视觉装饰来引起对这些区域的特别关注。

改动后： https://developer.apple.com/design/human-interface-guidelines/foundations/layout/

Respect key display and system features in each platform. Safe areas help you accommodate features like the corner radius and sensor housings on various devices, and avoid interfering with interactive system elements like the Home indicator and app switcher on iPhone and iPad. Safe areas also help you account for interactive components like bars, dynamically repositioning content if sizes change.

（由iOS翻译App翻译）尊重每个平台的关键显示和系统功能。安全区域可帮助您适应各种设备上的角落半径和传感器外壳等功能，并避免干扰iPhone和iPad上的家庭指示器和应用程序切换器等交互式系统元素。安全区域还可以帮助您考虑条形等交互式组件，如果大小发生变化，可以动态重新定位内容。
