提问by Tericky Shih
After update XCode 8.2, every time save simulator screen shot always made it crash. Even I reset content and settings still crash.
更新 XCode 8.2 后，每次保存模拟器屏幕截图总是使其崩溃。即使我重置内容和设置仍然崩溃。
Should I remove all simulator and install them again?
我应该删除所有模拟器并重新安装它们吗？
Update:
更新：
- 8.2.1 has same problem.
- 8.3 only Sierra supported.
- 8.2.1 也有同样的问题。
- 8.3 仅支持 Sierra。
The following is the crash report:

The crash seems to occur due to a segmentation fault, or more specifically a general protection fault, while calling the saveScreenShot:selector. Why it happens can depend on several things, so it's hard to say whether a reinstall would help.
崩溃似乎是由于分段错误，或更具体地说，是在调用saveScreenShot:选择器时发生的一般保护错误。为什么会发生这种情况取决于几件事，因此很难说重新安装是否会有所帮助。
In any case, if the screenshot (?S) function in simulator causes the crash, there's hardly anything you can do about it. The best option you have is probably to file a bug report to Apple.
在任何情况下，如果模拟器中的屏幕截图 (?S) 函数导致崩溃，您几乎无能为力。您拥有的最佳选择可能是向 Apple 提交错误报告。
Update:
更新：
I just updated to the 8.2 GM, and low and behold, ?S crashes for me as well. Although I'm getting KERN_INVALID_ADDRESSinstead of EXC_I386_GPFLT.
我刚刚更新到 8.2 GM，瞧瞧，?S 对我来说也崩溃了。虽然我得到了KERN_INVALID_ADDRESS而不是EXC_I386_GPFLT.
One workaround, for the time being, is copying the screen and pasting into Preview:
目前，一种解决方法是复制屏幕并粘贴到预览中：

Yeah, unfortunately, this is tripping over a bug in Foundation on OS X 10.11. You won't have the problem if you upgrade to macOS Sierra.
是的，不幸的是，这被 OS X 10.11 上的 Foundation 中的一个错误绊倒了。如果您升级到 macOS Sierra，您将不会遇到此问题。
If you cannot upgrade to Sierra right now, you can still take screenshots from the commandline:
如果您现在无法升级到 Sierra，您仍然可以从命令行截取屏幕截图：
xcrun simctl io booted screenshot <path to output file>
This is mentioned in the Xcode 8.2 Release Notes
这在Xcode 8.2 发行说明中提到
Simulator can crash when saving a screenshot when running on OS X El Capitan. (29182710) The crash does not occur on macOS Sierra.
在 OS X El Capitan 上运行时，保存屏幕截图时模拟器可能会崩溃。(29182710) 在 macOS Sierra 上不会发生崩溃。

Please find the below steps for getting the screenshot.
请按照以下步骤获取屏幕截图。
1) Go to Simulators -> Edit -> Copy Screen or you can use the shortcut (ctrl + cmd + c).
2) Open the Previewand go to File -> New from Clipboard or you can use the shortcut (cmd + n).
3) Now go to File -> Save or you can use the shortcut (cmd + s).
1) 转到模拟器 -> 编辑 -> 复制屏幕，或者您可以使用快捷方式 ( ctrl + cmd + c)。
2）打开预览并转到文件 - >从剪贴板新建，或者您可以使用快捷方式（cmd + n）。
3）现在转到文件 - >保存，或者您可以使用快捷方式（cmd + s）。

So an easier workaround is this:
所以一个更简单的解决方法是：
Run app in simulator (obviously)
In simulator go to Edit>Copy Screen
- Open Preview app
- Go back to simulator and save screenshot i.e. File>Save Screenshot
在模拟器中运行应用程序（显然）
在模拟器中去编辑>复制屏幕
- 打开预览应用
- 返回模拟器并保存屏幕截图，即文件>保存屏幕截图
Done!
完毕！
Not sure why this prevents the bug from occurring but it worked for me. It's faster than all the other methods described above.
不知道为什么这可以防止错误发生，但它对我有用。它比上述所有其他方法都快。

Solution 1
方案一
1) Go to Simulators > Edit > Copy Screen (??C)
1）转到模拟器>编辑>复制屏幕（??C）
2) Open Preview App > Go to File > New from Clipboard (?N) and Save (?S) to your favorite location on your machine
2）打开预览应用程序>转到文件>从剪贴板新建（？N）并保存（？S）到您机器上您最喜欢的位置
Solution 2:- Using the xcrun Xcode command-line utility
解决方案 2：- 使用 xcrun Xcode 命令行实用程序
Open Terminal Appand run the following command to take screenshot
打开Terminal App并运行以下命令进行截图
xcrun simctl io booted screenshot
xcrun simctl io booted screenshot
If you wish to save the captured screenshot to specific location
如果您希望将捕获的屏幕截图保存到特定位置
xcrun simctl io booted screenshot <path_to_output_file>
xcrun simctl io booted screenshot <path_to_output_file>

Another convenient way -> Shift+Command+4 - tap the space bar, tap on the window to get snapshot of the Simulator's window.
另一种方便的方法 -> Shift+Command+4 - 点击空格键，点击窗口以获取模拟器窗口的快照。
