The hidden zoom gesture has been around since iOS 11, but not many people know about it. To try it out, open Maps and hold your iPhone with one hand. Now, double-tap on a map with your thumb (or any other finger), keeping your finger on the screen on the second tap, then move your finger up to zoom in and down to zoom out.
