What's New in iOS 16.4 Beta

Apple just released the first betas of iOS 16.4, iPadOS 16.4, watchOS 9.4, and tvOS 16.4 to developers today.

Here's a look at all the changes we've spotted in iOS 16.4 beta so far.

Beta enrollment for iPhone and iPad
● Beginning with iOS & iPadOS 16.4 beta, members of the Apple Developer Program will see a new option to enable developer betas directly from Software Update in Settings. This new option will be automatically enabled on devices already enrolled in the program that update to the latest beta release. Your iPhone or iPad must be signed in with the same Apple ID you used to enroll in the Apple Developer Program in order to see this option in Settings. In future iOS and iPadOS releases, this new setting will be the way to enable developer betas and configuration profiles will no longer grant access. (101692915)

SwiftUI

● Always On Display system setting can now be configured with Focus Filters.

Web Push
Now with iOS and iPadOS 16.4 beta 1, we are adding support for Web Push to Home Screen web apps. Web Push makes it possible for web developers to send push notifications to their users through the use of Push API, Notifications API, and Service Workers all working together. A web app that has been added to the Home Screen can request permission to receive push notifications as long as that request is in response to direct user interaction — such as tapping on a 'subscribe' button provided by the web app. iOS or iPadOS will prompt the user to give the web app permission to send notifications. The user can then manage those permissions per web app in Notifications Settings — just like any other app on iPhone and iPad.

Home
After having been removed in iOS 16.2, it's once again possible to upgrade your Home architecture in iOS 16.4 beta.
