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 more on performance than on new features, 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.[2] 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. Security updates for iOS 12 have continued for four years following the release of iOS 13 for devices unable to run the newer operating system. The latest update, 12.5.7,[3] was released on January 23, 2023.
Overview[edit]
iOS 12 was introduced by Craig Federighi at the Apple Worldwide Developers Conference keynote address on June 4, 2018.[4] The first developer beta version was released after the keynote presentation,[5] with the first public beta released on June 25, 2018.[6] The initial release of version 12.0 was on September 17, 2018.
System features[edit]
Performance[edit]
Performance optimizations were made in order to speed up common tasks across all supported iOS devices.[7] 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 compared to iOS 11.[8]
Screen Time[edit]
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,[9] the amount of time the user used particular categories of apps (such as games),[10] and the number of notifications the user received.[11]
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.[12]
In January 2018, investors JANA Partners and the California State Teachers' Retirement System had issued a public letter to Apple, calling for them to take additional responsibility for the "unintentional negative consequences" that iPhones may have on younger users, and to seek out new ways to limit these effects.[13][14] In June 2018, after the announcement of the Screen Time feature, Tim Cook publicly admitted that he "was spending a lot more time than [he] should" on his phone.[15] JANA Partners and CalSTRS issued a second letter to express their support for the new feature.[16]
Shortcuts[edit]
A dedicated application in iOS 12 allows users to set up Shortcuts, automated actions that the user can ask Siri to perform.[10] 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[17] that Apple acquired in March 2017.[18][19]
ARKit 2[edit]
ARKit now allows users to share their view with other iOS 12-supported devices.[20] ARKit 2 additionally allows full 2D image tracking and incorporates the ability to detect 3D objects.[21]
CarPlay[edit]
CarPlay can now run third-party navigation applications.[10] (Waze, Google Maps, etc.)
