Exciting as the new iPhone X might sound, it's the software that makes the iPhone tick. With that in mind, here's what you need to know about iOS 11, the upcoming version of Apple's mobile and tablet operating system.
When can you download the iOS 11 update?
iOS 11 will be released today. The iPhone 8, iPhone 8 Plus and iPhone X will all ship with iOS 11. A push notification will be sent to devices when the download is ready.
Which devices support iOS 11?
The following devices are iOS 11 compatible:
What are iOS 11's key new features?
iOS 11 will include animated emojis, new camera modes designed to take advantage of the dual-lens versions of the iPhones and the introduction of Face ID to replace/augment Touch ID. Here are a few more ways iOS 11 will change how you use the iPhone and iPad.
The iPad is becoming even more like a Mac
Your at-a-glance guide to the iPhone X and iPhone 8
Alongside the new 10.5-inch and 12.5-inch iPad Pros, Apple demonstrated several new enhancements to iOS 11 on iPad. The most significant of these is the new dock, which is similar in appearance to the dock on macOS High Sierra.
You can dock more apps now and it serves as an advanced app switcher, as well. For example, if you drag an icon from the dock onto the screen, you can place it side-by-side with the app that's already on-screen. Where previously the dock was only accessible from the home screen, now you can bring it up wherever you are just by dragging your finger up from the bottom edge of the screen.
There's also a new app switching view, pictured above. It integrates the Control Center and presents recent applications in a grid with the dock at the bottom.
Key to these changes is the introduction of drag-and-drop support. This allows users to drag and drop elements from one app to another. For example, if you have the Notes app and Safari open at the same time, you could select text and images from a web page and then drag it across into a note.
The drag-and-drop facility is important to another new iOS 11 feature: the Files app.
Up to now, iOS never had a file manager in the traditional sense. Files belonged to specific applications, so you had to choose to open them in another app to move them around. The iCloud Drive app was an attempt to correct this, but the Files app is more powerful.
It combines all the files storage locally on your iPad with the files stored in the cloud. And it doesn't just support iCloud, it integrates with popular cloud storage providers like Dropbox and Box as well.
Siri is everywhere
Keen to show Apple can do AI as well as Google (we remain unconvinced), iOS 11 showcases several improvements to Apple's digital assistant.
It'll be harder for police to access your data
After Apple's battle with the FBI, over the locked iPhone of the San Bernardino terrorist, it has boosted iOS privacy protections. The new security tweaks (as we've detailed here) make it harder for law enforcement officials to extract details without the four or six digit passcode for the device.
Here are all the shiny new things Apple just announced
Apple has improved the voice of Siri, making it more natural. It can now say words in different ways. Apple used the example of three versions of the word "sunny". This should, in theory, allow Siri to use the right intonation based on the context of what it is saying. That's the theory, anyway.
Everything you do with Siri is now synced across all devices, all with end-to-end encryption. This means if you ask a question on your phone, Siri's answer will be available on your Mac or iPad at the same time. Siri's also learned a new trick: translation. It can translate common languages into English, and vice versa, and even supports Chinese translation.
Finally, it's learning more about what you do. For example, if you're viewing web pages about Iceland, Apple News might start showing articles about Iceland. If that sounds like the kind of tracking Apple's keen to avoid, you'd be right, but Apple says everything is encrypted and it's not tracking you to try to sell you stuff.
Apple Pay will get more useful at some point
During Apple's WWDC, where iOS 11 was revealed, it said the software will give users the ability to send money to individuals through Apple Pay using iMessage.
As Apple FAQ page explains: "Pay and get paid right in Messages, or tell Siri to pay someone, using the credit and debit cards they have in Wallet. When users get paid, they receive the money in their new Apple Pay Cash card in Apple Wallet and can use the money instantly".
Unfortunately, the release of the feature within iOS 11 has been delayed. In a statement published before the release Apple said the feature would be coming this autumn in a future update to iOS 11.
Lots of apps and features have been redesigned
Apple has tweaked the look and feel of iOS 11 in numerous ways.
The Control Center is now on just one screen and allows you to use 3D Touch on specific elements, such as the music controls, to reveal more detailed controls. It's not clear how this would work on devices that don't support 3D Touch, though.
The App Store redesign takes cues from the the Music and News apps. It's now split into a few key tabs: Today, Games, Apps and Updates.
The Today tab will be updated daily with different content, such as an App of the Day, tips on how to get the most out of popular apps and other app news. You can keep scrolling down to see the featured apps from previous days.
Your phone won't bug you when you're driving
Apple's added a 'Do Not Disturb while Driving' mode to iOS 11. It stops notifications and if someone sends you a message while driving, iOS 11 will automatically send a message back saying you can't respond. The mode will activate automatically based on your movement and whether you're connected to a car stereo.
Maps now includes indoor maps for a large number of international airports, as well as maps for popular malls in the US.
Apple has added Sonos-style music features
Not satisfied with the launch of HomePod, the Siri-enabled wireless speaker, Apple introduced several upgrades to its music ecosystem in iOS 11.
Speakers have been added to HomeKit, allowing people to control compatible wireless speakers from the Home app. Bear in mind, however, HomeKit requires extra hardware to work, so don't expect your existing speakers to work with the Home app. Apple's also launched the new AirPlay 2 protocol, which adds support for collaborative party playlists.
The Music app now shows music your friends are listening to and developers have greater access to Apple Music through a new MusicKit API. Shazam, for example, is using the API to add music it identifies to your library, while fitness apps can use the API to control your music from within their apps.
Augmented reality is Apple's next big thing
Arguably the biggest addition is the new ARKit API, which allows developers to add augmented reality features to their apps.
Apple demonstrated adding virtual objects to a desk on stage, showing how its system could identify surfaces and place objects with the correct scale. For example, a coffee cup on a desk would be the correct size for the desk.
Apple is working with partners already and hinted that IKEA is already working on how it could use these AR features. Check out our pick of the best ARKit demos for a taste of what developers are doing with it.
