A month after releasing iOS 11.3 and just one week after seeding the third beta, Apple has seeded the fourth beta of the upcoming iOS 11.4 for developers.
You can download iOS 11.4 beta from Apple’s Developer Center or over-the-air if you are a registered developer once you have installed the proper configuration from the Developer Center.
This beta introduces ClassKit framework for education institutions supporting features that were announced on March 27 at the iPad and education-focused event.
For general users, iOS 11.4 will bring all the features that were removed from iOS 11.3 ahead of release, like support for iMessages to be stored in iCloud instead of your iPhone allowing better syncing capabilities. This feature also allows you to download messages on all your iDevices and if you delete a message from one device, it removes it from all the devices, just how iCloud is supposed to work seamlessly.
iOS 11.4 will also include AirPlay 2 features through which you’ll be able to play the same audio content in different rooms on AirPlay 2 supported devices.
Although it was evident that there would be support for stereo sound on the HomePod in the initial 11.4 beta, it was removed in the second beta thanks to bugs, and it’s not clear whether this feature will make a comeback.
