SwiftUi 无法同时满足约束 - 当焦点位于文本字段和键盘打开时

Question

当我打开带有文本字段的工作表，并将焦点放在文本字段上时，会出现键盘并显示此消息：

 2021-02-06 22:29:35.817858+0100 OrientationEPS[4026:269878] [LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. 
Try this: 
    (1) look at each constraint and try to figure out which you don't expect; 
    (2) find the code that added the unwanted constraint or constraints and fix it. 
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(

    "<NSAutoresizingMaskLayoutConstraint:0x6000030b3250 h=--& v=--& _UIButtonBarButton:0x7fea6492cf40.height == 0   (active)>",
    "<NSLayoutConstraint:0x6000030fce60 _UIUCBKBSelectionBackground:0x7fea64930c50.bottom == _UIButtonBarButton:0x7fea6492cf40.bottom - 6   (active)>",
    "<NSLayoutConstraint:0x6000030ec7d0 V:|-(6)-[_UIUCBKBSelectionBackground:0x7fea64930c50]   (active, names: '|':_UIButtonBarButton:0x7fea6492cf40 )>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x6000030fce60 _UIUCBKBSelectionBackground:0x7fea64930c50.bottom == _UIButtonBarButton:0x7fea6492cf40.bottom - 6   (active)>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.

我不太明白绿色部分说的是什么......（NSAutoresizingMaskLayoutConstraint - NSLayoutConstraint）你能解释一下这条消息吗？我可以添加我的代码，但我不知道我必须发布哪一部分......

此错误消息出现在我的所有工作表上，并以文本字段为焦点。（我的应用程序中有 3 个）

我在更新到 12.4 后才开始注意到这一点（尽管我之前可能已经错过了）。经过大量调查，我发现每次 UITextField 变为活动状态时我都会收到相同的消息。

为了确认这一点，只需制作一个只有一个 UITextField 的简单应用程序，无论约束如何设置或不设置，都会出现相同的警告。
