Apple is releasing the third developer beta for its next-gen operating systems this evening. The company released developer beta 2 in mid-June, followed by the first public beta a week later. And now, it’s releasing developer beta 3 for iOS 13, iPadsOS 13, macOS Catalina, tvOS 13, and watchOS 6.

Apple announced iOS 13, ipodOS, tvOS 13, watchOS 6, and macOS Catalina at its WWDC 2019 press conference in early June.

Developer beta 3 introduces a bunch of fixes for iOS 13 and the other operating systems. It includes a lot of fixes for all the operating systems, and you can find the appropriate changelogs for the updates.

It’s still early days for these betas, though. Despite the fact that Apple has already shipped a public beta for these operating systems, they are still very buggy and include a lot of reliability issues. The new iOS 13 developer beta 3, for example, is not available for the iPhone 7, or the iPhone 7 Plus. And it also includes a bunch of issues related to important third-party apps like WhatsApp. So if you are going to install any of the updates on your devices, make sure to read through the changelog before deciding to put them on your device.
