Apple has released iOS 10, which it says is the biggest release ever of the world’s most advanced mobile operating system, featuring a huge update to Messages that delivers more expressive and animated ways to message friends and family, like stickers and full-screen effects. It’s available at the Apple App Store.

iOS 10 introduces the ability for Siri to do more by working with apps, redesigned Maps, Photos, Apple Music and News apps, and the Home app, delivering a way to manage home automation products in one place. iOS 10 opens up incredible opportunities to developers with Siri, Maps, Phone and Messages, according to Craig Federighi, Apple’s senior vice president of Software Engineering.

“iOS 10 adds Siri intelligence into QuickType and Photos, automates your home with the new Home app and opens up Siri, Maps, Phone and Messages to developers — while increasing security and privacy with powerful technologies like Differential Privacy,” he adds.

Messages is the most frequently used iOS app, and with iOS 10 it is more expressive and fun with animated and personalized ways to message friends and family, according to Federighi. Messages includes animations, such as balloons, confetti or fireworks that can take over an entire screen to celebrate a special occasion, invisible ink to send a message only revealed after a friend swipes over it, and for added personalization, handwritten notes. Automatic suggestions make it easy to replace words with emoji, Tapback creates a quick and simple way to respond with just a tap and rich links let you see content inline and play media without ever leaving your conversation.

iOS 10 brings the power of the App Store to Messages, opening up new opportunities for developers to create fun new ways for users to communicate in a thread, including stickers to be peeled and pasted into conversations, the ability to quickly personalize GIFs or edit photos, send payments or schedule dinner or a movie, all from within Messages, says Federighi.

In iOS 10, Siri can be extended into new areas. For the first time, developers can build on the intelligence Siri offers and let users interact directly with apps using just their voice. SiriKit helps developers design their apps to work with Siri for messaging, phone calls, photo search, ride booking, personal payments and workouts, or use Siri to control CarPlay apps, access climate controls or adjust radio settings within automakers’ apps.

Maps in iOS 10 gets a redesign. Now open to developers with new extensions, apps like OpenTable can integrate bookings right into Maps, and services like Uber and Lyft can make it easier for users to book a ride, without ever leaving the Maps app.

Federighi says Maps is even smarter with new intelligence that proactively delivers directions to where you most likely want to go next, based on your routine or appointments on your calendar. Once a route is planned, Maps can search along the route for gas stations, restaurants, coffee shops and more and provides an estimate of how the stop impacts the length of your trip. 

Photos in iOS 10 helps you rediscover favorite and forgotten occasions from your photo library by automatically surfacing them in Memories. Memories scans all your photos and videos and finds favorite and forgotten events, trips and people, and presents them in a beautiful collection. A Memory also contains the Memory Movie, an automatically edited movie with theme music, titles and cinematic transitions. 

Memories uses advanced computer vision to group the people, places and things inside your images into albums with on-device facial, object and scene recognition. This intelligence brings Memories and related photos to life in a way that’s personal and meaningful to you, while maintaining your privacy.

The Home app is deeply integrated into iOS, delivering a secure way to set up, manage and control your home in one place. Accessories can be managed individually or grouped into scenes so they work together with a single command and can be controlled by using Siri. They can be managed remotely or set up for home automation with Apple TV, and can respond with automatic triggers set by time of day, location or action.

Support for HomeKit continues to expand globally with nearly 100 home automation products adopting HomeKit this year, bringing support for thermostats, lights, window shades, door locks, video cameras and more to the Home app. Later this year, leading home builders, including Brookfield Residential, KB Home, Lennar Homes and R&F Properties, will begin integrating many of these HomeKit devices into new homes.

Apple Music has an all-new design and purportedly uses a new design language that allows the music to become the hero and a new structure that makes it easy to navigate and discover new music. The Library, For You, Browse and Radio tabs have been completely redesigned to provide an even greater sense of place, and Apple has added a Search tab to make finding music even easier, says Federighi.

iOS 10 features a redesigned News app with a new For You, organized into distinct sections that make it easier to find stories, support for breaking news notifications and paid subscriptions, he adds.

In iOS 10, Raise to Wake automatically wakes the screen as you raise your iPhone. Notifications, Today view and Control Center are accessible with just a swipe or a press, and there’s deeper 3D Touch integration with the iPhone 6s and iPhone 6s Plus.

In iOS 10, Siri intelligence brings new QuickType features, including contextual predictions to surface relevant information based on location, calendar availability or contacts; and predictive typing supports multiple languages without switching keyboards.

It adds integration for third-party VoIP calls, voicemail transcription and a new caller ID extension for spam alerts. Built-in app updates include Safari split-view for iPad, Notes collaboration and Live Photos editing.

Apple Pay can now be used to make secure and private purchases on participating websites using Safari, in addition to paying in-stores and within apps. Bedtime Alarm in the Clock app lets you set a regular sleep schedule and receive bedtime reminders.

Federighi says security and privacy are fundamental to the design of Apple hardware, software and services. iMessage, FaceTime and HomeKit use end-to-end encryption to protect your data by making it unreadable by Apple and others. iOS 10 uses on-device intelligence to identify the people, objects and scenes in Photos, and power QuickType suggestions. Services like Siri, Maps and News send data to Apple’s servers, but this data is not used to build user profiles.

Starting with iOS 10, Apple is using technology called Differential Privacy to help discover the usage patterns of a large number of users without compromising individual privacy. In iOS 10, this technology will help improve QuickType and emoji suggestions, Spotlight deep link suggestions and Lookup Hints in Notes, according to Federighi.
