I have saved some screenshots in the iPhone Simulator running iOS 5, but I can\'t find them.
I had this problem before, and it took me frickin\' ages to find them i
In the Organizer view just right-click a screenshot and select "Show in Finder...".
This will open the screenshots folder in the Finder for you.
With Xcode 9+, Simulator saves screen shot file on (logged-in user's) Desktop
and it's default path.
To change default path (with Xcode 9+), press and hold ⌥ Option (alt) button from keyboard, while you take a screen shot. It will show to a dialog with file storage options and also allows to set/change default path.
