I don't know how much this gets used these days, but I have updated my guide to braille screen input with iOS 27's changes. I wrote the first version way back when iOS 7 came out and we got BSI. I will never forget how magical it felt to use braille right on my phone. It was life-changing, and still is. https://www.applevis.com/guides/guide-braille-screen-input-ios-ipados
