You can now download iOS 11.4 beta 1 for iPhone, iPad and iPod touch devices. Here's how you can install it right away.
Developers Can Download iOS 11.4 Beta for iPhone and iPad Today With ClassKit Framework
During its education event a while back Apple announced that it would be releasing a new version of iOS in a short time that would introduce the ClassKit framework to developers. That software version for iPhone and iPad devices is iOS 11.4 and developers can download it right now if they have a fully functional developer membership with Apple.
Just like any other beta update released before today, you can download iOS 11.4 beta either over the air without losing your files, or you can download the entire IPSW file and do a clean restore using iTunes. I would highly prefer going through the former route as it ensures that your files and settings remain in tact while you test out the beta. Still, I would highly recommend that you take a complete backup of your device just in case you decide to downgrade back to iOS 11.3.
Download iOS 11.4 Beta Over the Air
Head over to the Apple Developer Program website and sign in by clicking on the Account tab at the top. Remember, the Apple Developer Program costs $99 a month if you wish to sign up right now. Once logged in, click on the Download option on the left from the dashboard. Now simply find the iOS 11.4 beta download, then select over the air installation method, which will prompt you to install a beta profile onto your device. Accept the terms, restart your device, and then head over to Settings > General > Software Update in order to download and install the update.
Clean Install iOS 11.4 Beta
As mentioned above, you will lose your files and settings if you are planning to do a clean install of iOS 11.4 beta. So make sure you back everything up using iCloud or iTunes before proceeding. Once everything is in order, follow the 'over the air' method for download except that you are going to download iOS 11.4 beta IPSW file in the last step rather than the beta profile. You can then use iTunes to restore your device.
