Just days after Apple launched iOS 11.4 beta 5, it's got another beta release ready to go.
Apple today released iOS 11.4 beta 6 to registered developers. If you're a dev, you can get this update over the air by going into Settings > General > Software Update, or on the web by going to Apple's Developer Center.
The update to iOS 11.4 includes Messages in iCloud, which will sync your iMessages across devices. Also included is AirPlay 2, which adds new features like the ability to play the same audio in multiple rooms on all devices. However, it's unclear which features will make the cut into the public release of iOS 11.4.
Apple hasn't said when it'll release iOS 11.4 to the public. However, now that we're on the sixth beta release, a public launch could happen in the coming weeks. Apple is kicking off its Worldwide Developers Conference on June 4th, so it's possible that iOS 11.4 will be released then.
