It was announced at the company's Worldwide Developers Conference on June 13, 2016, and was released on September 13, that year.
It was succeeded by iOS 11 on September 19, 2017.
iOS 10 incorporates changes to 3D Touch and the lock screen.
There are new features to some apps: Messages has additional emojis and third-party apps can extend functionality in iMessage, Maps has a redesigned interface and additional third-party functions, the Home app manages "HomeKit"-enabled accessories, Photos has algorithmic search and categorization of media known as "Memories", and Siri is compatible with third-party app-specific requests, such as starting workouts apps, sending IMs, using Lyft or Uber or to use payment functions.
iOS 10 is also the last version of iOS to support devices with a 32-bit processor, and it is also the last version of iOS to support 32-bit apps.
Reviews of iOS 10 were positive.
Reviewers highlighted the significant updates to iMessage, Siri, Photos, 3D Touch, and the lock screen as welcome changes.
The third-party extension support to iMessage meant it was "becoming a platform", although the user interface was criticized for being difficult to understand.
Third-party integration in Siri was "great", although the voice assistant was criticized for not having become smarter than before.
Reviewers were impressed with the image recognition technology in Photos, although noting it was still a "work in progress" with a higher error rate than the competition.
3D Touch "finally feels useful" and "works in almost every part of the OS".
The lock screen was "far more customizable than before", and reviewers enjoyed that notification bubbles could be expanded to see more information without needing to unlock the phone.
A month after release, iOS 10 was installed on 54% of iOS devices, a "slightly slower migration" than for the release of iOS 9, speculated as being caused by an early release issue that may have "put some [users] off downloading the update".
User adoption of iOS 10 steadily increased in the following months, eventually totaling 89% of active devices in September 2017.

iOS 10.3.4 was released on July 22, 2019, to address a time rollover issue that could impact GPS location performance and could cause the system date and time to be incorrect.
The Control Center has been redesigned and split into three pages: one for general settings, such as quick toggles for airplane mode and orientation lock, one for audio controls and one for controlling HomeKit (internet of things) appliances, if used.
3D Touch capabilities have been added to several toggles.
Apps can show a widget when their home-screen icon is accessed with 3D Touch.
Most default apps included with iOS devices can be hidden from the home screen and 're-downloaded' from the App Store.
The app is also hidden from other places, such as the "Today" view, the Settings app and "Share Sheets", through which the user can interact with the app from within another app.
This feature was first hinted at during an interview in September 2015, in which Apple CEO Tim Cook stated that Apple was "looking at" allowing customers to remove unused stock apps.
iOS 10 allows users to prioritize certain app downloads by using 3D Touch.
QuickType virtual keyboards, which provide word-completion capabilities, can predict likely responses to questions and suggest relevant information based on location, calendar availability or contacts.
The "Define" feature in previous iOS versions has been replaced by "Look Up", and now expands its utility from just providing definitions to retrieving information from locations, web browsing history, downloaded apps, suggested websites, and more.
The QuickType keyboard will allow the user to type in multiple languages if the user selects the desired languages in the "Dictionary" and "Keyboard" settings menus.
The user has the ability to change keyboard settings specifically for physical keyboards (such as autocorrect and auto-capitalization).
The "slide to unlock" mechanism on the lock screen has been removed in favor of pressing the home button.
Similar to the feature on the Apple Watch, "Raise to Wake" wakes up the device when the user lifts it.
This function requires a device with an M9 motion coprocessor or newer.
The "Today" view of Notification Center has been replaced by widgets, and is accessible by swiping from left to right.
On the iPad, widgets can be displayed in a two-column layout.
The Notification Center no longer has a "Today" view.
Notifications, now larger, can expand to display more information and all unread notifications can be cleared at once, using 3D Touch.
Apps that need to be updated frequently can now have notifications that update live.
The Notification Center contains a Spotlight search bar.
A new Magnifier setting was added which allows users to triple-click the home button to launch the Camera app with magnification enabled.
There are also new "Color Filters" settings to compensate for a user's color blindness.
For the Messages application, users can now turn on Low Quality Image mode, which saves "your poor iPhone from stuffing itself full of images" based on new animated stickers and GIFs that can be sent in iMessage.
The Wi-Fi menu in Settings now shows warnings about the security of a network and whether a network lacks Internet connectivity.
This is shown to the user as small subtext under the Wi-Fi's network's name.
"Raise to Wake" can be enabled or disabled in Settings.
In iOS 10.2, a "Preserve Settings" feature allows users to set the Camera app to launch with certain settings by default.
Options include launching with the Video or Square mode rather than the Photo mode, preserving the last-used filter, and preserving the capture settings for Live Photos.
Music added to Apple Music on one device can now be automatically downloaded to other devices using the "Automatic Downloads" setting.
In iOS 10.3, Settings was updated to feature information relating to a user's Apple ID account in the main menu, and features a section that allows users to see which old, unmaintained apps won't work in future versions of iOS.
Additionally, users can now see a breakdown of their iCloud storage.
The user can enable a setting to have Siri announce incoming callers, with options for "Always", "Headphones & Car", "Headphones Only", and "Never".
iOS 10 now allows users to rearrange and remove apps from their CarPlay display, through Settings.
In iOS 10.3, Maps on CarPlay added electric vehicle charging stations.
As part of the overall Continuity features introduced in iOS 8, a new Universal Clipboard feature allows users of Mac personal computers running macOS Sierra and iOS devices running iOS 10 to easily copy material to and from different devices through iCloud.
iOS 10 features new sound effects for locking the device and for keyboard clicks.
In the event that a device detects liquid in the Lightning port, a notice warns the user to disconnect the Lightning cable and allow the port to dry.
iOS 10 also allows TTY calls to be made without any additional hardware.
iOS 10 allows developers to buy advertisement spots in the App Store when users search for content.
It also brings back the "Categories" section, which replaces the "Explore" section introduced in iOS 8.
In iOS 10.3, developers gained the ability to respond to user reviews, and "Helpful" and "Not Helpful" review labels can help surface the most relevant customer reviews.
Music will no longer stop playing when the Camera app is launched, unless the user decides to record a video or take a Live Photo.Live Photos can be taken with filters (previously only available for still photos).
In iOS 10.1, the iPhone 7 Plus received a new depth of field portrait camera mode, using both the wide-angle and telephoto lenses on the phone to "create shallow depth of field portrait photos with blurred backgrounds".
The Clock app now employs a dark theme.
A new "Bedtime" feature reminds the user when to go to bed to get the desired amount of sleep.
There is also a new stopwatch face, accessed by swiping to the left.
The Contacts app in iOS 10 allows users to set default phone numbers and email addresses for contacts who have multiple numbers or addresses.
The app also allows the user to add and remove contacts from the Favorite Contacts list.
In the app, users can add compatible HomeKit accessories, such as locks, lights, and thermostats, and then directly control the appliances through the app.
A "Scenes" panel allows many devices to be controlled at once to fit a mood or setting.
Geo-fencing activates scheduled sequences following the user's location.
The Mail app now allows users to unsubscribe from mailing lists with an Unsubscribe button.
Users can dismiss the message to unsubscribe for a particular mailing list by tapping the "X" at the top right corner, preventing the Mail app from displaying the unsubscribe button for that mailing list again later.
Mail can filter messages, either by unread/read, or by categories.
iOS 10 also changes how email threading works, by placing the oldest email at the top by default.
An option in Settings lets users revert to the previous threading system with the most recent message on top.
Additionally, the new threaded conversations allow users to tap a message to see a scrollable stream of messages inside the thread.
A marker can be automatically placed to indicate the user's parked car.
The marker can also tell the user when they last parked their car, and a Notes field allows the user to enter information, such as parking garage number, in the app.
The app now helps users find the nearest gas station, fast-food restaurant or coffee shop, by swiping up from the bottom of the screen.
Maps also estimates how long the detour will take.
Users can add third-party extensions to the Maps app, which enable additional functionality, such as a restaurant-booking extension can help the user reserve a table from inside the Maps app.
Users can now pan and zoom while in navigation mode.
The app displays the current temperature and weather conditions in the bottom right corner.
In iOS 10.3, the app also allows the user to see a weather forecast by using 3D Touch on the current temperature.
This functionality allows users to see an hour-by-hour breakdown of the area that they are looking at.
The Messages app incorporates its own App Store, which lets users download third-party iMessage apps that can be accessed within iMessage conversations.
The Messages App Store has three navigation fields: Featured, Categories, and Manage.
The app has been updated to include many visual effects.
Chat bubbles, for example, can be sent with a "loud" or "gentle" animation that the recipient sees upon receiving.
"Invisible ink" effect obscures the message until the recipient swipes across it.
Full-screen effects like balloons, confetti or fireworks can be sent.
There is also support for interactions similar to the Apple Watch, such as sending quick sketches and recording and sending the user's heartbeat.
In order to use the screen and bubble effects, the Reduce Motion setting needs to be turned off.
Messages now allows users to send handwritten notes.
This is done by turning the device to landscape mode for iPhones (landscape or portrait for iPad users) and then tapping the handwriting squiggle.
The Messages app automatically saves recently used notes, to make it easier to send them again.
A handwritten message can be deleted in the same way an app is deleted; by holding down on the message and pressing Delete.
The message can also be saved as a picture file.
New emojis have been added, as well as additional features related to emoji.
Emojis appear 3x bigger if messages are sent with up to three emojis and no text, the keyboard can now predict emojis to use, and an emoji replacement feature attempts to match words in messages and replace them with emojis of the same meaning.
Since the Game Center app has been removed, Messages now handles actions such as inviting friends to a game.
Read receipts can now be turned on or off for individual contacts rather than for all contacts.
The Music app has been redesigned, with an emphasis placed on usability.
The "For You" section has been reorganized, with a playlist offering daily music recommendations.
