Sometimes the simulator get hung for no obvious reasons. Xcode shows in the status display that the app is running.
有时模拟器会因为没有明显原因而挂起。Xcode 在状态显示中显示应用程序正在运行。
If this happens i click the home button of the simulator and then immediately click the app icon again. Then the app appears again and everything is visible wihtout stopping the app or the debugger.
如果发生这种情况，我单击模拟器的主页按钮，然后立即再次单击应用程序图标。然后应用程序再次出现，一切都可见，无需停止应用程序或调试器。

In some cases where hitting Reset Content and Settings...does not work, it may be due to the background the of the screen being set to Default. This was the issue in my case.
在某些点击Reset Content and Settings...不起作用的情况下，可能是由于屏幕的背景设置为Default。这就是我的问题。
If this is the case (for anyone who may be having the same problem I did), just click on empty area of the storyboard screen being displayed and switch the background from Defaultto something else, like Whitefor example:
如果是这种情况（对于可能遇到我遇到的相同问题的任何人），只需单击正在显示的故事板屏幕的空白区域并将背景切换Default为其他内容，White例如：
Change Backgroundfrom this:
Background从此改变：

I initially made a not needed Referencing outlet of button in a internal View [inside main View] to main View. Whenever i used to make changes on storyboard, "main View" [not entire screen] displayed black screen. After removing button reference, it worked properly.
我最初在一个内部视图 [inside main View] 中创建了一个不需要的按钮引用出口到主视图。每当我曾经在情节提要上进行更改时，“主视图”[不是整个屏幕] 都会显示黑屏。删除按钮引用后，它工作正常。
