推荐答案

从Xcode 11.3.1开始，SwiftUI不支持针对列表项的自定义滑动操作.根据Apple SDK演变的历史，直到下一个主要的SDK版本(在WWDC 2020年)或更高版本，我们才可能获得支持.

As of Xcode 11.3.1, SwiftUI doesn't support custom swipe actions for List items. Based on the history of Apple’s SDK evolution, we’re not likely to see support until the next major SDK version (at WWDC 2020) or later.

您可能最好实现其他用户界面，例如将切换按钮添加为列表项的子视图，或将上下文菜单添加到列表项.

You would probably be better off implementing a different user interface, like adding a toggle button as a subview of your list item, or adding a context menu to your list item.

请注意，您必须使用Beta 4或更高版本才能在iOS上使用contextMenu修饰符.

Note that you must be on beta 4 or later to use the contextMenu modifier on iOS.
