Apple today released the fourth build of iOS 11 for testing to developers. Those opted in to receive public betas should get the update later this week. This comes two weeks after the third beta was released to the same parties.
To install the new build, head over to Settings > General > Software Update. Tap “Download and install” next to the iOS 11 Developer Beta 4 listing and you’ll be good to go. I recommend jumping on a Wi-Fi network first alongside plugging in your device beforehand as a) you don’t want data overcharges on your bill and b) you don’t want your phone or tablet to die during the installation process.
iOS 11 packs a revamped Control Center, redesigned notifications, improvements to Siri including an all-new voice, Do Not Disturb While Driving, and an all-new interface for the iPad with better productivity features, a macOS-style Dock, and a new multitasking view. There’s even an official Files app for all iOS devices that lets you access files stored on your device without having to hunt down a third-party service to do so.
New changes in the build include some really welcome ones. You can finally swipe on notifications in the Notification Center to clear them or take action; there’s new icons for Contacts, Reminders, and Notes; and there’s a new UI for when you wanna open a notification and your phone is locked by Touch ID. There’s also various other tweaks throughout the system worth checking out if you install the new build.
We’ll update this article with any further changes.
