Is this an Xcode bug and/or issues with the complexity of my UI?

I was having the same problem for a long time on a very complex app as well: The key is all in isAccessibilityElementbeing set to YES. UI testing and accessibility go hand-in-hand. The way I think about it is that the device needs to be able to interact with the element, since ostensibly, the user wouldn't be able to.
我在一个非常复杂的应用程序上也遇到了同样的问题很长一段时间：关键isAccessibilityElement在于设置为 YES。UI 测试和可访问性是相辅相成的。我的想法是设备需要能够与元素进行交互，因为从表面上看，用户无法做到。
I did this twice:
我做了两次：
In
cellForRowAtIndexPath-cell.isAccessibilityElement = YESIn
awakeFromNibin aUITableViewCellsubclass -self.isAccessibilityElement = YES
在
cellForRowAtIndexPath-cell.isAccessibilityElement = YES在
awakeFromNib一个UITableViewCell子类-self.isAccessibilityElement = YES
Hope that helps, and good luck!
希望能帮到你，祝你好运！

Try manipulating with items isAccessibilityElement property. As far as I know containers like tableView should have this property set to NO in order to items contained inside them be accessible
尝试使用项目的 isAccessibilityElement 属性进行操作。据我所知，像 tableView 这样的容器应该将此属性设置为 NO，以便可以访问其中包含的项目
Assistive applications can get information only about objects that are represented by accessibility elements. Therefore, if you implement a custom control or view that should be accessible to users with disabilities, set this property to YES. The only exception to this practice is a view that merely serves as a container for other items that should be accessible.
辅助应用程序只能获取有关由辅助功能元素表示的对象的信息。因此，如果您实现了残障用户应该可以访问的自定义控件或视图，请将此属性设置为 YES。这种做法的唯一例外是一个视图，它仅用作其他应该可访问的项目的容器。

You need to add key path value to your UI elements as below. For an example, if you are using a tableviewthen select it in the Storyboard and then click on Identity Inspector. Now enter the following value isAccessibilityElementin the key and tick the checkbox as shown in the image below.
您需要将键路径值添加到您的 UI 元素，如下所示。例如，如果您使用的是 ，tableview则在故事板中选择它，然后单击Identity Inspector。现在isAccessibilityElement在键中输入以下值并勾选复选框，如下图所示。
Also if you can't tap on the UITableViewCell or the subclasses, then enable the Accessibility option as shown below.
此外，如果您无法点击 UITableViewCell 或子类，请启用辅助功能选项，如下所示。
hereafter it should work just fine.
此后它应该可以正常工作。
