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

Please try this approach for taking screenshot

You can take videos and screenshots of Simulator using the xcrun Xcode command-line utility. To take a screenshot, run the command xcrun simctl io booted screenshot. To take a video, run the command xcrun simctl io booted recordVideo <filename>.<file extension>. (9887264)

For a static screenshot, an easier and faster workaround is to type COMMAND+SHIFT+4, then hit the space bar until the simulator window is selected, then click on the simulator window to save the screenshot.
