Apple just released iOS 14 beta 3 and iPadOS beta 3 to developers today. As expected, it has a number of user interface tweaks, icon changes, and performance improvements. Here is our look at everything new in iOS 14 beta 3.

When you upgrade your iPhone or iPad to the latest beta update, the first thing you might notice is that performance has been improved. The jitteriness from beta 2 is gone. App switching and widget modifications are smoother than before. It’s still not perfect yet, as it’s a beta, but Apple has definitely made some progress here.
