Today Apple has released iOS 13.3 developer beta 1, as well as betas of iPadOS 13.3, watchOS 6.1.1, and tvOS 13.3.
iOS 13.3 Developer Beta 1
Apple’s developer page doesn’t show release notes yet. One issue that I’ve seen happen with iOS 13.2 is that some users report that it kills background tasks and apps a bit too aggressively.
This version is intended exclusively for software developers to test their apps and start adopting the new technologies in iOS. Make sure to back up your device and install only on systems you are prepared to erase if necessary.
Released: November 5, 2019
