Now that iOS has a grid overlay feature built into accessibility/voice control, is it possible to tap into that functionality in app development, and allow for customization of a grid overlay? No voice control, no numbers on the screen - ability to position and design a grid and then have it overlay everything you do on the screen until you decide to turn it off.Unfamiliar with all of this, so apologies if my explanation of what I'm asking is bad, and if I've slected the wrong location for this post...
