Edit Text Easier
Editing text on iPhones has always been a bit wonky. But Apple has improved the text selection in iOS 13 with new gesture-based controls.
You can copy text with a three-finger, pinch-in motion, and paste it with a three-finger pinch-out motion, for example. You can also just drag the text cursor anywhere you want it, as well as undo and redo typing with a forward or back gesture.
