The good news for those who want to testiOS 13 , iPadOS and macOS Catalina today is that Apple has released Public Beta for all three operating systems for people to test together.

For those who want to participate in the test, will have to register on the Beta Program (here). Originally, iOS 13 plans to start beta release in July. But it seems that the development status is faster than expected Making it come out faster than I thought about a week. Of course, the first Beta is usually full of bugs. Who will update, please be aware that the usage may not be as smooth as you think. And there may be problems with slow performance And eat more battery than usual
