> What is surprising to me is that using a Back button that's at the top of the phone would be acceptable This is why iOS added the back gesture, over ten years ago now, when phones started getting taller. > from an iOS developer perspective, this is not always free As an iOS developer since years before that gesture was added, I must disagree. The gesture comes for free unless you break it. Apps without back gestures smell like bad orgs. If you build some custom navigation you won't magically get it, because it's interactive and you need to make your navigation interact, but people are generally discouraged from building custom navigation. If you do go down that route it involves an astonishing amount of code to reproduce interactive pop. > and the back gesture itself only works within your own app unless you do additional work I'm afraid I also have no idea what you're trying to say here.
