What does the iOS Simulator’s “Motion Control” menu item do?

Question

In the iOS Simulator that ships with Xcode 5, there is a menu item Window → Motion Control. Clicking it seems to have no effect. Does anyone know what it does? Is it related to either the M7 coprocessor on recent iOS devices, or the “Switch Control” accessibility feature?

Answer 1

I can’t be sure what it does, but I disassembled the iOS Simulator MainMenu.nib using NibUnlocker, and that menu item sends a method called -showMotionControl: to the GuiController class. My best guess is that it is related to an Apple internal feature that never shipped. Perhaps a way to simulate gyro and/or accelerometer values?

Answer 2

This menu item was only visible in early beta versions of Xcode 5.1 and has been dropped in Xcode 5.1 beta 4.

So I presume that this feature won't be shipped with the final version of Xcode 5.1 and that's why we never got to use it.
