Developers, you can now download iOS 13 beta 2 for iPhone, iPod touch and iPadOS 13 for iPad with a ton of bug fixes and performance enhancements.

First beta of iOS 13, in terms of bugs, was so bad that Apple even put up a warning on its website saying: “If you’re interested in living on the edge and trying out the great new features in iOS 13, we strongly advise waiting for the many bug fixes and refinements coming to the public beta next month.” However, today’s update fixes a lot of things, but that does not mean in any way that you should go ahead and install it right now on your daily driver since the public beta is still not available for download, meaning beta 2 still have a fair bit of instabilities. Also, the latest beta is not available as a fresh over the air download for those that need it. You have to install iOS 13 beta using iTunes and then get the subsequent updates over the air.
