Apple releases first developer preview of iOS 11.4 beta

Not long ago, Apple officially pushed out iOS 11.3, tvOS 11.3 and watchOS 4.3 system updates. However, a few days after the official version was released, at midnight on April 3, Apple started testing the next operating system version update for iPhone, iPad, Apple Watch and Apple TV. Currently, the first beta test version of iOS 11.4, tvOS 11.4 and watchOS 4.3.1 has been released for developers.

If you are a developer or have a developer account, the first iOS 11.4 beta developer preview system can already download the complete firmware package through the Apple Developer Center. Of course, devices that are already in the developer beta state can also perform system updates via OTA. As for the iOS 11.4 beta public test version, it is usually available a few days after the developer preview version is released, and the fastest interval is one day.

I believe that everyone has already known about the iOS 11.4 system version through Apple's press conference on March 27, and they also roughly know what content should be updated in this version of the system. Obviously, the new ClassKit education framework will be one of the focuses. In iOS 11.4, developers will be able to use ClassKit to easily update their own apps to give full play to the role of schoolwork apps, such as allowing their apps to easily assign various activities and view student progress.

At the same time, "AirPlay 2" may also reappear, because Apple removed it in the official version of iOS 11.3, and did not provide a specific reason. In the earliest iOS 11.3 beta, Apple tested three developer versions and then removed it, and it has never appeared since then. Another feature that may appear in iOS 11.4 is iCloud Messages. As for the Chinese region, it may add binding to more city bus cards in the future.

Users who have completed the iOS 11.4 developer preview update in the early morning pointed out that the iOS 11.4 beta version is confirmed to include the "AirPlay 2" function, and Apple TV is included in the "Home app" again, and HomePod also provides stereo options, etc. What other updates are provided by the first developer preview of iOS 11.4? I believe that more users will reveal it in the middle of the day today.

The version number of the first developer preview of iOS 11.4 is 15F5037c. Although it can be upgraded directly through the configuration file, it is not recommended to upgrade non-public beta versions, at least not for daily use of devices, because data loss is really possible.
