iOS 17 will be released in September of the year, but not all features will be released at WWDC immediately after the release of the firmware.
This is already a standard practice for Apple, when not all functions are effective at the time of the release of the system. As a rule, they come out in the next updates before the end of the year.
Application Journal
In the iOS 17 app, the Journal will appear, which will work like a personal diary. Users of the ability to create in the record it, add photos and videos to them.
The application will be available until the end of 2023.
Shared Apple Music playlists
Apple Music users on iOS 17 create collaborative playlists, add tracks to them, and rearrange them. But at the start, this function will not work.
Transfer files via AirDrop over the Internet
AirDrop typically uses Wi-Fi and Bluetooth to transfer files. Also a prerequisite is the presence of devices next to a friend with a friend.
In iOS 17, AirDrop can wait for file transfers over the Internet if the Wi-Fi or Bluetooth connection suddenly drops or one of the iPhones leaves the AirDrop activity.
