/*
    During Dark Mode migration for macOS, I found it helpful to have a global hotkey
    which toggled between Light/Dark Mode.
  
    This hack attempts to do something similar for iOS.
  
    1) Add your main window in -applicationDidFinishLaunching:
    2) Triple tap the window (I tend to do this near the title bar) to flip between light and dark.
