It's been a long time since the iOS operating system that powers the iPhone has not brought any changes to the interface. The last time we saw a drastic change to the iOS interface was in ios 7.
Latest, according to a Bloomberg report, Apple plans to introduce major changes to the iOS interface through the upcoming iOS 19 update this year. These interface changes will cover iPhone devices, iPads and also Mac laptops through MacOS.
It is said that a number of elements will be based on VisionOS, and Apple will bring changes to the design of icons, menus, applications, windows, and so on. These changes are expected to make it easier for users to control their devices than before.
Apple usually holds its annual WWDC event around June, where we may see in advance the designs they will offer through this interface update.
