The iOS 13.1 update will include updates that were initially planned for iOS 13, including Siri being able to read incoming messages aloud; Siri shortcuts being able to be added to HomeKit automations; sharing an ETA with friends; and the ability to import photos directly into an app when a camera is connected to an iOS device.
Other updates, like, audio sharing between two sets of AirPods, and HomePod and AirPlay 2-enabled speakers being able to access songs, playlists, and radio stations with Apple Music are being pushed to “later this fall.”
