After releasing new beta versions of iOS 13 yesterday for developers, Apple has released beta 3 versions of iOS 13, iPadOS, tvOS 13 and macOS Catalina for Public beta testers this morning.
iOS 13 Public beta 3 comes in at a nearly 700MB download. Those part of the Public beta can update their iOS devices by going to Settings > General Software Update. This third beta should bring the same changes that came with the beta 4 version made available to developers yesterday.
You can click here to sign up for Apple’s free Public beta program, but be warned these are still betas and will include bugs. So it’s best to install them on secondary devices.
