After upgrading to Xcode 8.2, We are facing the Xcode crash issue every time we save the screen shot (⌘S) in simulator. Even Reset Content and Settings… option won’t help.
After spending a lot time, I came to know that Simulator crash only happen on OS X El Capitan when saving a screenshot and not on macOS Sierra.
The crash seems to occur due to a segmentation fault, or more specifically a general protection fault, while calling the saveScreenShot: selector.
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
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>
