保存屏幕截图时Xcode 8.2模拟器崩溃

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.

Answer 4

So an easier workaround is this:

1. Run app in simulator (obviously)

2. In simulator go to Edit>Copy Screen

3. Open Preview app
4. Go back to simulator and save screenshot ie File>Save Screenshot

Done!

Not sure why this prevents the bug from occurring but it worked for me. It's faster than all the other methods described above.

Answer 5

Solution 1

1) Go to Simulators > Edit > Copy Screen (⌃⌘C)

2) Open Preview App > Go to File > New from Clipboard (⌘N) and Save (⌘S) to your favorite location on your machine

Solution 2:- Using the xcrun Xcode command-line utility

Open Terminal App and run the following command to take screenshot

xcrun simctl io booted screenshot

If you wish to save the captured screenshot to specific location

xcrun simctl io booted screenshot <path_to_output_file>

Answer 6

Another convenient way -> Shift+Command+4 - tap the space bar, tap on the window to get snapshot of the Simulator's window.
