iOS11

iOS 11 is the eleventh major release of Apple's iOS operating system for iPhone and iPad. Announced at the Worldwide Developers Conference on June 5, 2017 and released to the public on September 19, 2017, it introduced a broad set of changes focused on productivity for iPad while updating the iPhone experience.

The update was compatible with iPhone 5s and newer, iPad mini 2 and newer, iPad Air and newer, iPad Pro models, and the iPod touch (6th generation). It marked a shift toward device-wide enhancements in multitasking, file management, and augmented reality, while also refreshing the App Store and system apps.

Key features included a redesigned App Store, a new Files app for managing documents across iCloud Drive and local storage, and ARKit for augmented reality development. iPad users gained substantial multitasking improvements, including a new Dock, a redesigned home screen, and support for Drag and Drop, Split View, and Slide Over. The Control Center was redesigned to function on a single page, and iOS 11 added built-in screen recording. Other notable additions included AirPlay 2 for multi-room audio, improved Do Not Disturb While Driving, and updates to Photos and Messages to enhance user workflows. ARKit enabled developers to create more immersive augmented reality experiences on compatible devices.

iOS 11 received several follow-up updates before being superseded by iOS 12 in September 2018. The release is recognized for expanding iPad usability and for introducing tools that broadened the range of apps and experiences available on iPhones and iPads.
