As an iOS dev, every year there are significant amounts of APIs that make doing your day to day job easier that you can't use if you don't stay on the latest, especially with actively developed ones like SwiftUI. So probably nothing needed specifically, but definitely something productive.
- iOS 15 introduced a "proper" way to restore scroll position and page state.
- iOS 16 introduced the super nice "expanded" font width, used in certain address bar setup.
- iOS 16.4 fixed a bug where the address bar could not be properly attached to the keyboard.
