Xcode 8.2 simulator crash when save screen shot

Question

After update XCode 8.2, every time save simulator screen shot always made it crash. Even I reset content and settings still crash.

Should I remove all simulator and install them again?

Update:

• 8.2.1 has same problem.
• 8.3 only Sierra supported.

Answer 1

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.

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.

Update:

I just updated to the 8.2 GM, and low and behold, ⌘S crashes for me as well. Although I'm getting KERN_INVALID_ADDRESS instead of EXC_I386_GPFLT.

One workaround, for the time being, is copying the screen and pasting into Preview:

Answer 2

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.

If you cannot upgrade to Sierra right now, you can still take screenshots from the commandline:

xcrun simctl io booted screenshot <path to output file>

This is mentioned in the Xcode 8.2 Release Notes

Simulator can crash when saving a screenshot when running on OS X El Capitan. (29182710) The crash does not occur on macOS Sierra.

Answer 3

Please find the below steps for getting the screenshot.

1) Go to Simulators -> Edit -> Copy Screen or you can use the shortcut (ctrl + cmd + c).
2) Open the Preview and 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).

Or you can also refer the below GIF presentation.
