iPhone X introduced very similar gestures as seen on Sailfish OS (https://support.apple.com/en-us/HT208204). They might be a bit alien at first, but once you get used to them, they are in my opinion far more powerful (one-handed use), faster and more intuitive than buttons. I have used Sailfish OS based phones since 2013 as my daily driver and Android/iOS UX feels very clumsy to me.
