iOS 12 is the twelfth major release of the iOS mobile operating system developed by Apple Inc. Aesthetically similar to its predecessor, iOS 11, it focuses less on new functions than on performance, quality improvements and security updates. Announced at the company's Worldwide Developers Conference on June 4, 2018, iOS 12 was released to the public on September 17, 2018.[3] It was succeeded for the iPhone and iPod Touch by iOS 13 on September 19, 2019 and for the iPad by iPadOS 13 on September 24, 2019.

More than two and a half years after its release, iOS 12 continued to receive regular security updates for older devices that did not support iOS 13, with the last 12.5.4 update released on June 14, 2021.

System features[]

Performance[]

Performance optimizations were made in order to speed up common tasks across all supported iOS devices.[31] Tests done by Apple on an iPhone 6 Plus showed apps launching 40% faster, the system keyboard activating 50% faster, and the camera opening 70% faster.[32]

Screen Time[]

The Screen Time usage information screen in iOS 12 on an iPhone X

Screen Time is a new feature in iOS 12 that records the amount of time a user spent on the device. The feature also displays the amount of time the user used particular apps,[33] the amount of time the user used particular categories of apps (such as games),[34] and the number of notifications the user received.[35]

Screen Time also provides blocking features to limit usage of apps (with time limits) or set other restrictions such as on purchases or explicit content. It replaces Restrictions in the iOS Settings app, but can also be used by adults to limit their own usage. These features can be used with or without a passcode. Without setting a passcode, the limits can easily be bypassed but may serve as a useful reminder of usage goals.[36]

Shortcuts[]

A dedicated application in iOS 12 allows users to set up Shortcuts, automated actions that the user can ask Siri to perform.[34] Using the Shortcuts app, a user can create a phrase and type in the action they want Siri to do for them. Once they tell the phrase to Siri, Siri will automatically do the task they set for it in the Shortcuts app. The Shortcuts app replaces the Workflow app[37] that Apple acquired in March 2017.[38][39]

ARKit 2[]

ARKit now allows users to share their view with other iOS 12-supported devices.[40] ARKit 2 additionally allows full 2D image tracking and incorporates the ability to detect 3D objects.[41]

CarPlay[]

CarPlay can now run third-party navigation applications.[34] (Waze, Google Maps, etc.)

iPad[]

The Voice Memos and Stocks apps are now available for iPads.[42]

Control Center is separated from the app switcher on iPad and can be opened with a swipe down on the top right corner. In addition, iPhone X-style gestures are introduced across all iPads running iOS 12.[43]

Keyboard[]

In iOS 12, the trackpad mode (which allows the user to freely move the cursor) is enabled by long-pressing the space bar on devices without 3D Touch.[44]

App Switcher[]

For devices with gesture navigation and no home button (iPhone X and later), users can now force quit applications by swiping up from the bottom of the screen (without having to press and hold on them when in the app switcher).[45]

Exposure Notification API[]

On December 14, 2020, Apple released iOS 12.5, which includes the Exposure Notification API (backported from iOS 13) that provides access to the Apple / Google privacy-preserving contact tracing system that Apple have developed jointly with Google.[46][47] This is provided to support digital contact tracing which came to light during the COVID-19 pandemic.[48]

App features[]

Messages[]

Messages in iOS 12 introduces a new type of customizable Animoji called "Memoji" which allows a user to create a 3D character of themselves. Apple also introduced Koala, Tiger, Ghost and T-Rex Animojis.[49] In addition, Apple added new text and GIF effects similar to those found on other social media applications.

FaceTime[]

FaceTime gains support for Animoji and Memoji, as well as new text and GIF effects similar to those found on other social media applications and in the Messages application.[32]

iOS 12.1, released on October 30, 2018, adds the ability to include up to 32 people in a FaceTime conversation. This feature is only supported with video by devices with the Apple A8X or Apple A9 chip or later; it is only supported for audio on iPhone 5S, iPhone 6, and iPhone 6 Plus, and is not available at all on iPad Mini 2, iPad Mini 3, and iPad Air.[50] Group FaceTime was disabled on January 28, 2019 due to a software bug that allowed calls to be answered by the caller rather than the recipient, allowing video and audio to be transmitted unless the call was declined.[51] The functionality got restored on February 7, 2019, with the release of iOS 12.1.4. Group FaceTime remains disabled on devices running iOS 12 that are affected by the bug.

Measure[]

Main article: Measure (Apple)

Measure is a native AR application that allows the user to take measurements of real objects. It also works as a level,[32] a feature that was originally packaged as part of the Compass app.[52]

Photos[]

Apple Photos has been completely redesigned with four new tabs, including "Photos", "For You", "Albums", and "Search". The new "For You" tab replaces the "Memories" tab previously found in iOS 11 and makes sharing recommendations, creates short-length video collages, photo editing suggestions, as well as featured photos from a specific day.[32]

While the "Photos" and "Albums" tabs received only a few cosmetic changes, the "Search" tab includes new Artificial Intelligence and Machine Learning features which show the user photos by place and categories (e.g. animals, cars, objects).[53]

Notifications[]

Notifications are now grouped by application and have a "manage" button to turn off notifications for that app or to deliver them quietly right from the Notification Center without having to go into the Settings application.[54]

Do Not Disturb[]

Do Not Disturb gives users more options for automation. Users can hide notifications indefinitely or scheduled like previously, but can also hide notifications for 1 hour, until a time of day, until leaving a location, or until the end of a scheduled event in Calendar.[55]

Voice Memos and Stocks[]

Voice Memos and Stocks are supported on iPad, and have a newer design. Stocks was integrated with Apple News to show financial and other related news.[56]

Apple Books[]

iBooks was renamed Apple Books, and the app was redesigned, with five new tabs, including "Reading Now", "Library", "Book Store", "Audio Books", and "Search".[57] The new app design is similar to that of Apple Music, and has been praised for its simplicity in allowing users to easily navigate their book library.[citation needed]

Safari[]

Safari receives an update to Intelligent Tracking Prevention. This includes a feature which allows the user to disable social media "like" and "share" buttons.[58]

Maps[]

Apple Maps had started to be rebuilt from the ground up by relying on first-party map data instead of using map data provided by third parties. This allows for more accurate directions and predictions on the fastest routes.[59] The new maps were rolled out in sections and the entire US completed by the end of 2019.[60]

Problems[]

Rainbow flag emoji[]

After a rainbow flag emoji with an interdictory sign over it appeared on Twitter, several users accused Apple of encouraging anti-LGBT attitudes. However, Emojipedia has clarified that this occurs when a user tweets the two emojis together and is not an intended feature. This can be used with other emojis as well.[61][62][63]

FaceTime eavesdropping issue[]

Main article: FaceTime § Group FaceTime bug

A FaceTime issue impacting several versions of iOS 12 (versions 12.1–12.1.3) allowed users to call someone via FaceTime and hear the audio coming from their phone before answering the call,[64] before the bug was fixed in iOS 12.1.4.[15]

Supported devices[]

Any device that supports iOS 11 can be upgraded to iOS 12.[65] However, devices with an A7 or A8 chip and 1GB of RAM, such as the iPhone 5S, 6, 6 Plus, and the iPod Touch (6th generation), all have limited support. These are the list of the devices that support iOS 12:
