Apple recently released iOS 15.3 to the public, which includes a series of new features. In addition, Apple has provided developers with the first beta versions of iOS 15.4 and iPadOS 15.4. Apple has started to stop pushing security updates on iOS 14, hoping to push users to update to the latest version. A recent leaked iOS 16 image on the Internet shows that Apple will bring interactive widgets and redesigned icons.
As you can see from the leaked iOS 16 pictures, the interactive widget contains not only apps, but also widgets and other shortcuts in the control center. The new gadget is internally known as InfoShack, though it's uncertain if the name will change until Apple officially announces it. The new widget is ideal for users, giving them more control over what appears on the screen, seeing more information at a glance, and accessing the features they need faster.

In addition, leaked iOS 16 pictures show Apple redesigning the icons, a bit like the styles in macOS Monterey, which means that Apple may be looking to simplify the UI design of its devices. Although it is not too early to conclude, perhaps the design will change, but at least apple design ideas can be seen. Overall, little is known about the design details of the iOS 16 system, and Apple will make the updated information public at the next WWDC event.
Many people have seen the new design and said that the design style of iOS is getting closer and closer to the former Windows Phone.
