Swiping is I think how most people use nav on an iPhone at this point. The back button at the top did make a lot more sense on the original models where the screen was small enough that you could do everything with a single hand.

it's not an Android phone. Please go back to Android if what you want is Android. I don't mean that in jest, but in all seriousness. You've gotten used to a certain way of doing things for over a decade, keep at it.

It makes no sense for you to change if you don't like the other way of doing things and it makes even less sense to discuss "why why why isn't the new system working like my old one".

No need when you can just use edge navigation. The button in the top left is just there for users not as handy with their devices.

Valid point but I personally have no issue with the swipe gesture on my Max sized phone.
