我使用的是标准状态栏，没有以任何方式修改它。

I think you can safely ignore it. New versions of iOS/macOS sometimes contain informational debugging messages, and they generally get removed at the next release.
我认为你可以放心地忽略它。新版本的 iOS/macOS 有时包含信息性调试消息，它们通常会在下一个版本中被删除。

Same issue was occurring for me too. To overcome this, I did this
同样的问题也发生在我身上。为了克服这个，我这样做了
Goto Target -> Deployment Info -> Unchecked 'Hide status bar'
转到目标 -> 部署信息 -> 取消选中“隐藏状态栏”
This one resolved my issue. For me, this was the 'Deployment Info' setup.
这个解决了我的问题。对我来说，这是“部署信息”设置。

In my case, it was hiding navigation bare by
就我而言，它隐藏了导航
self.navigationController?.isNavigationBarHidden = false
self.navigationController?.isNavigationBarHidden = false
When you are hiding the navigation bar, it hides status bar too!. just use
当您隐藏导航栏时，它也会隐藏状态栏！。只是使用
self.navigationController?.navigationBar.isHidden = true
self.navigationController?.navigationBar.isHidden = true
instead. And you will have your status bar back.
反而。您将恢复状态栏。

I am also seeing this warning appear, and in answer to Question 1, I am also seeing potentially very nasty behaviour associated with it.
我也看到此警告出现，并且在回答问题 1 时，我还看到了与之相关的潜在非常讨厌的行为。
Running something close to a basic sample animated triangle Metal app, but with
运行接近于基本示例动画三角形 Metal 应用程序的东西，但使用
renderPassDescriptor.colorAttachments[0].loadAction = .load
such that the frame isn't cleared every frame. What seems to be happening is that every other time the warning message is logged, iOS also gets some part of its management of graphics state confused so that I witness a violent flashing of parts of the image (which then goes away again later).
这样帧就不会每帧都被清除。似乎正在发生的事情是，每隔一次记录警告消息时，iOS 也会对其图形状态管理的某些部分感到困惑，因此我目睹了图像部分的猛烈闪烁（然后再次消失）。
How likely this situation would be to emerge in a 'real' app I'm not sure, but it's definitely not something you want users to end up seeing.
我不确定这种情况在“真实”应用程序中出现的可能性有多大，但这绝对不是您希望用户最终看到的。
I haven't fixed the problem here thus far; 'Hide status bar' and 'Requires full screen' settings don't help.
到目前为止，我还没有解决这个问题；“隐藏状态栏”和“需要全屏”设置无济于事。

To answer Question 2 drawing upon PeterT answer that addresses Question 1: not only you can not get rid of this warning, but you mustn't, cause it means that the underlying problem is anything, but benign. At least in some scenarious.
回答问题 2 借鉴解决问题 1 的 PeterT 答案：不仅您无法摆脱此警告，而且您也不能，因为这意味着潜在的问题是任何问题，但都是良性的。至少在某些情况下。
This also means that the DEC Field Circus Engineer dance swapping the wheels that flat in meta info for the project would rightfully make you look like a clown.
这也意味着 DEC Field Circus Engineer 的舞蹈交换项目元信息中平坦的轮子会让你看起来像个小丑。

I was able to get rid of this warning, by checking the "Requires Full Screen" in Target-> Deployment Info.
通过检查Target-> Deployment Info 中的“需要全屏”，我能够摆脱这个警告。
Checking this option may have some side-effects in iPad, so you should do it having this in mind.
选中此选项可能会在 iPad 中产生一些副作用，因此您应该考虑到这一点。
