The evergreen question of "how do you go back and/or close an app on IOS?"
This experience put a major dent in my perception of the "Apple has the most intuitive UI" narrative.
Case in point: The YouTube app for Apple TV. Everything (pausing, playing, changing subtitles) has been done opposite to the standard player found in every other app. You cannot use the main button to pause and resume, for example. Recently they broke swiping. Normally, you swipe the remote to navigate between UI elements such as squares in a grid or in lists with a light touch. It's very fluid, like a touch screen. But the YT app has added severe "inertia" to touch gestures, and you now have to "fling" your finger on the remote trackpad to navigate. Everything feels syrupy and stuck.
YouTube and Amazon's Prime TV app are the two worst apps I've ever used on Apple TV. I believe they both use some non-native UI toolkit that doesn't respect native OS conventions and doesn't even try to. Pretty incredible given the size and budgets of these companies.
Androids do have universal back button at the bottom on the phone or the same swipe gesture if you want but iphones do not.
Sometimes swipe (the direction and position is a guessing game), sometimes and x (right or left ) and the behavior is inconsistent too (back or close)
There are some guidelines but more often than not seems like every app has it's own method and you need to get used to it
You swipe up and remove the application from the stack, all processes of the application is killed.
Background processing has strict limits, and you need permissions to run longer than that, and for some use cases, there are no recourse. OS swaps you out or freezes the app.
If you want an app to work in the background, don't kill it, period. Push notifications are handled by the OS and is not hindered by this.
Think for example reddit, you open a thread, how do you go back?
You open the "reply window, now ho you ho back? Maybe close it directly?
I Android this is all handled by the same function and is often ranked as the most frustrating design choice in IOS
They all are very different applications and have very different designs, yet the arrow is there.
To be honest, I baffled at your question for a second or so, because I never thought about that, yet the method is so universal that I was not thinking about it at all.
It's not "getting used to", I feel like that gesture is less practical. It involves or using the "circle" to assist on how to use the gesture (creating a black void on the screen that you need to plan your use of the phone around) or having the swipe that 1) is not as reliable in my opinion and 2) can be triggered accidentally
For me is like claiming that touch screens on cars are the future and people are too old to get used to it.
Swipes are of course nice because they allow for the same interactions without taking any screen real-estate. And I have to say it quite consistent across the iOS apps I use.
When I get handed iPhone I have no clue on how to even open an additional tab in Safari and any finger gestures do not do the things what I expect nor there is a lick of indication on how to do something. It's all just a memorized magical incantations at this point. But hey you are familiar with them so it's easy to bash on everyone who is not in yours eco-system.
Meanwhile when there's an X button or arrow to the left I always know what it's going to do aside from one or two overly creative Android apps.
Why change what works fine? Maybe that's the definition of being too old, can't be bothered to change to new things.
