Adjusting the hinge angle in the iPhone Duo simulator

In Xcode 27.1, the iPhone Duo simulator has a slider for controlling the hinge angle, but it isn't visible by default. To reveal it, we need to hold the Option (⌥) key while the simulator is focused.

The slider appears in the controls at the bottom of the simulator window, replacing the buttons for choosing a folded or open position. While holding Option, we can drag the slider to adjust how far the hinge is open. When we release the key, the position buttons reappear.
