'''iOS 8''' is the [[iOS version history|eighth major release]] of the [[iOS]] [[mobile operating system]] developed by [[Apple Inc.]], being the successor to [[iOS 7]]. It was announced at the company's [[Worldwide Developers Conference]] on June 2, 2014, and was released on September 17, 2014. It was succeeded by [[iOS 9]] on September 16, 2015.<ref>{{cite web |first=Russell |last=Brandom |title=iOS 9 will be released on September 16th |url=https://www.theverge.com/2015/9/9/9245073/apple-ios-9-download-release-date-iphone-upgrade |website=[[The Verge]] |publisher=[[Vox Media]] |date=September 9, 2015 |access-date=December 30, 2016 |archive-date=October 25, 2016 |archive-url=https://web.archive.org/web/20161025164014/http://www.theverge.com/2015/9/9/9245073/apple-ios-9-download-release-date-iphone-upgrade |url-status=live }}</ref>
App updates in the release included the new [[Health (Apple)|Health]] app, which can aggregate data from different fitness apps, as well as enabling a Medical ID accessible on theed 63% usage share, a notable 16% increase from the October measurement.
iOS 8 incorporated significant changes to the operating system. It introduced a [[application programming interface|programming interface]] for communication between apps,<ref>{{Cite web|last=Byford|first=Sam|date=2014-06-02|title=iOS 8 apps can talk to each other|url=https://www.theverge.com/2014/6/2/5773080/ios-8-apps-can-talk-to-each-other|access-date=2021-10-14|website=The Verge|language=en|archive-date=April 9, 2022|archive-url=https://web.archive.org/web/20220409211618/https://www.theverge.com/2014/6/2/5773080/ios-8-apps-can-talk-to-each-other|url-status=live}}</ref> and "Continuity", a cross-platform ([[Macintosh|Mac]], [[iPhone]], and [[iPad]]) system that enables communication between devices in different product categories, such as the ability to answer calls and reply to [[SMS]] on the Mac and iPad. Continuity includes a "Handoff" feature that lets users start a task on one device and continue on another. Other changes included a new [[Spotlight (software)|Spotlight Suggestions]] search results feature that provides more detailed results, Family Sharing, where a family can link together their accounts to share content, with one parent as the administrator with permission controls, an updated keyboard with QuickType, providing contextual predictive word suggestions and Extensibility, which allows for easier sharing of content between apps. Third-party developers got additional features to integrate their apps deeper into the operating system, including support for widgets in the Notification Center, and the ability to make keyboards that users can replace the default iOS keyboard with.
App updates in the release included the new [[Health (Apple)|Health]] app, which can aggregate data from different fitness apps, as well as enabling a Medical ID accessible on the lock screen for emergencies, support for [[iCloud#iCloud Photo Library|iCloud Photo Library]] in the Photos app, which enables photos to be synchronized and stored in the [[Cloud storage|cloud]], and [[iCloud Drive]], which lets users store files in the cloud and browse them across devices. In iOS 8.4, Apple updated its Music app with a streaming service called [[Apple Music]], and a 24-hour radio station called [[Apple Music 1]].
iOS 8 was well received. Critics praised Continuity and Extensibility as major features enabling easier control and interaction between different apps and devices. They also liked the QuickType keyboard word suggestions, and highlighted Spotlight Suggestions for making the iPhone "almost a portable search portal for everything.” However, reviewers noted that the full potential for iOS 8 would only be realized once third-party developers integrated their apps to support new features, particularly widgets in the Notification Center.
Roughly a week after release, iOS 8 had reached 46% of iOS usage share. In October 2014, it was reported that the adoption rate had "stalled,” only increasing by "a single percentage point" from the previous month. This situation was blamed on the requirement of a high amount of free storage space to install the upgrade, especially difficult for iPhones sold with 8 or 16 [[gigabyte]]s of maximum storage space. The following December, iOS 8 had reached 63% usage share, a notable 16% increase from the October measurement.

== System features ==
=== Continuity ===
iOS 8 introduced Continuity, a cross-platform ([[Macintosh|Mac]], [[iPhone]], and [[iPad]]) system that enables communication between devices in different product categories. Continuity enables phone call functionality for the iPad and Mac, in which calls are routed through the iPhone over to a secondary device. The secondary device then serves as a speaker phone. This also brings [[SMS]] support to the iPad and Mac, an extension of the [[iMessage]] feature in previous versions.<ref name="Continuity">{{cite web |first=Neil |last=Hughes |title=How to use iOS 8 Continuity between your iPhone & iPad for calls, texts, apps & more |url=http://appleinsider.com/articles/14/09/17/how-to-use-ios-8-continuity-between-your-iphone-ipad-for-calls-texts-apps-more |website=AppleInsider |date=September 17, 2014 |accesssess-date=December 22, 2016 |archive-date=September 11, 2018 |archive-url=https://web.archive.org/web/20180911191808/http://appleinsider.com/articles/14/09/17/how-to-use-ios-8-continuity-between-your-iphone-ipad-for-calls-texts-apps-more |url-status=live }}</ref>
Continuity adds a feature called "Handoff," that lets users start a task on one device and continue on another, such as composing an e-mail on the iPhone and then continuing it on the iPad before sending it on the Mac. In order to support Handoff and Continuity, Macs needed to have the [[OS X Yosemite]] operating system,<ref>{{cite web |first=Lance |last=Whitney |title=Apple's Handoff brings proximity awareness to your devices |url=https://www.cnet.com/news/apples-new-hand-off-brings-proximity-awareness/ |website=[[CNET]] |publisher=[[CBS Interactive]] |date=June 2, 2014 |access-date=December 22, 2016 |archive-date=April 19, 2019 |archive-url=https://web.archive.org/web/20190419031818/https://www.cnet.com/news/apples-new-hand-off-brings-proximity-awareness/ |url-status=live }}</ref> which was released in October 2014,<ref>{{cite web |first=Jacob |last=Kastrenakes |title=OS X Yosemite will be available today from the Mac App Store |url=https://www.theverge.com/2014/10/16/6978157/mac-os-x-yosemite-release-mac-app-store-october-16th |website=[[The Verge]] |publisher=[[Vox Media]] |date=October 16, 2014 |access-date=December 22, 2016 |archive-date=July 13, 2019 |archive-url=https://web.archive.org/web/20190713095936/https://www.theverge.com/2014/10/16/6978157/mac-os-x-yosemite-release-mac-app-store-october-16th |url-status=live }}</ref> as well as support for [[Bluetooth low energy]].<ref name="Continuity"/>
