推荐答案
关于这一点，您可能注意到或未注意到的一件非常奇怪的事情是，在WKWebView类中，有一个对scrollView的描述，从理论上讲，它是假定的". "添加到该类中，但scrollView不存在.可以在下面的照片中看到:
One really weird thing about this that you may or may not have noticed is that in the WKWebView class, there is a description of the scrollView that is theoretically "supposed" to be in the class, but the scrollView is not there. This can be seen in the photo below:
我会说这可能是Apple的一个怪异过程，但是在iOS类中，出现了相同的描述，但这次有一个实际的scrollView:
I would say that it could be a weird procedure of Apple's, but see in the iOS class, the same description is present but with an actual scrollView this time:
除非我在这里缺少一些重要的东西，否则可能意味着以下两件事之一:
Unless I am missing something major here, this would likely mean one of two things:
- 应该有一个scrollView但没有(即它被Apple意外删除了??)
- scrollView已从macOS WKWebView中删除，但是描述被意外地留在了类中?
无论哪种方式，这都是一个非常奇怪的发现.
Either way this is a very weird finding.
您可能要考虑对此做进一步的研究，也许提交Swift错误报告.
You might want to consider doing some further research on this, and perhaps filing a Swift bug report.
有人向我指出，此滚动视图实际上是仅iOS的属性，而不必要的注释是bug.
It was pointed out to me that this scroll view is in-fact a iOS only property, and the unnecessary comment is the bug.
