On Xcode 9.1 the Pixel Accurate
option is disabled and grayed out under the Window
menu.
How can I take App Store screenshots without this option?
The original answer is wrong!
Russ from the Apple Simulator team says:
To take app store screenshots uncheck the "Optimize rendering for Window Scale" option in the Debug menu. I recommend turning this back on normally as it improves rendering performance. Double-clicking does not make the device use native resolution, that's just an accident due to the size of device you tested with and the size of your screen.

ORIGINAL ANSWER (DOES NOT WORK RELIABLY):
Make sure Window -> Show Device Bezels is unchecked.
Double click the simulator's toolbar (the top bar listing the device and OS).
Note - sometimes, double-clicking the toolbar will just minimize the window to the dock. Alternately, simply click OSX menubar Window->Zoom.
Hello happy days, the simulator resizes and provides the right resolution for App Store screenshots.
