iOS 13 isn’t available to the public yet, but Apple is wrapping up the release and working on the next version of iOS.
iOS 13.1 Developer Beta
The iOS 13.1 developer beta, as well as iPadOS 13.1, are available as an over-the-air update if you’re already running the betas. Some iOS 13 features, like Automations in Shortcuts, have been removed from recent beta releases. It seems Apple is saving that and others for iOS 13.1.
Ultimately this is a good thing, because it’s a sign that Apple is taking its time with certain features, instead of rushing to get them out with iOS 13 with potential bugs.
