# Microsoft SwiftKey

Microsoft SwiftKey is a virtual keyboard app originally developed by TouchType for Android and iOS devices. It was first released for Android in July 2010, followed by an iOS release in September 2014 after Apple's implementation of third-party keyboard support.

## History

The company behind SwiftKey was founded in 2008 by Jon Reynolds, Ben Medlock and Chris Hill-Scott. Today, their head office is located at the Microsoft offices in Paddington, London, and their other offices are located in San Francisco, California and Seoul.
In September 2013, SwiftKey announced a series B finance round totaling $17.5 million led by Index Ventures, along with Octopus Investments and Accel Partners.
In May 2014, SwiftKey hired James Bromley as COO.
In February 2016, SwiftKey was purchased by Microsoft for USD$250 million (~USD$311 million in 2023).
In May 2020, the app was rebranded as Microsoft SwiftKey to reflect its present ownership.
In September 2022, Microsoft announced that they were ending support for the iOS version of SwiftKey. The app was ultimately removed from the App Store on 5 October 2022 However, in November 2022, Microsoft announced that they decided to reverse their decision to discontinue SwiftKey for iOS devices. The app was relisted on 18 November, with Microsoft assuring future updates for the app. The company cited "customer feedback" as a reason for SwiftKey's return.

## Overview

Microsoft SwiftKey is a virtual keyboard released on the Android and iOS operating systems. The purpose of the app is to increase efficiency while typing on a mobile phone. According to the Microsoft SwiftKey website, SwiftKey allows the user to speed up their typing process by "giving them more accurate autocorrect and predictions by learning their writing style".

## History
### Beta

SwiftKey was first released as a beta in the Android Market on 14 July 2010, supporting seven languages.

### SwiftKey X

On 14 July 2011, SwiftKey X was released to the Android Market as an upgrade to SwiftKey. The upgrade brought updated features and SwiftKey X introduced a dedicated app for tablets called SwiftKey Tablet X. New features included:

### SwiftKey for iOS

SwiftKey released an iOS application on 30 January 2014, called Swiftkey Note, which incorporates SwiftKey's predictive typing technology as a custom toolbar attached to the top of the regular iOS keyboard.
Starting with iOS 8, released in the second half of 2014, the operating system enables and supports third-party keyboards use. SwiftKey confirmed that it was working on a keyboard replacement app.
Starting with iOS 13, the system keyboard came with a built in QuickPath mechanism, which works similarly to SwiftKey's swiping feature.
SwiftKey for iOS was announced to be deprecated in September 2022. In November 2022, however, Microsoft reverted this decision.

### SwiftKey for iPhone

SwiftKey Keyboard for iPhone, iPad and iPod Touch launched in September 2014 to coincide with the launch of Apple's iOS 8 update. It was unveiled at TechCrunch Disrupt in San Francisco.
The app includes the word prediction and auto-correction features, familiar to the Android product, SwiftKey Cloud backup and sync and personalization, and a choice of color themes.
It reached No. 1 in the free US App Store charts and the company confirmed it had been downloaded more than 1 million times on the first day of launch.

### Further development

On 27 February 2012, the SwiftKey SDK was launched. This allows developers on multiple platforms and programming languages to access SwiftKey's core language-engine technology for their own UI or virtual keyboard.
In June 2012, SwiftKey released a specialized version of its keyboard called SwiftKey Healthcare. It is a virtual keyboard for iOS, Android, Windows Phone and BlackBerry devices that offers next-word predictions based on real-world clinical data. In October 2012, SwiftKey Healthcare won the Appsters Award for Best Enterprise App 2012.
In April 2016, SwiftKey released a keyboard that emulated William Shakespeare's speech called ShakeSpeak in observance of the 400th year of the author's death. The app was co-developed with VisitLondon.com to promote more tourism to the metropolitan area of London.
SwiftKey integration was included with Windows 10 beginning with the October 2018 Update. However, these features were later removed from Windows 10 beginning with the May 2020 Update.

## Controversy

In 2015, NowSecure reported a vulnerability present in the version of SwiftKey pre-installed on Samsung devices. This would occur when the keyboard attempted to update its language pack. Samsung has since released security and firmware updates to mitigate the issue. However, TechCrunch published an article on why the issue happened because of how Samsung implemented the keyboard system on its devices.
In 2016, SwiftKey users began reporting that the app was displaying personal details as suggested words to other users who did not have previous connections. Other issues included foreign languages and obscene words. SwiftKey responded by disabling cloud sync for word suggestions and releasing an update to mitigate the issue.
