IOS 13

iOS 13 is the thirteenth major release of iOS, being the successor to iOS 12 and the predecessor to iOS 14. It was announced at WWDC 2019 on June 3, 2019 alongside tvOS 13, watchOS 6, iPadOS and macOS Catalina, before being released to the general public on September 19, 2019.

History
The corresponding operating system for supported iPads was spun off into iPadOS from version 13.1. Support for HomePods was moved to tvOS with version 13.4. In May 2020, Apple released iOS 13.5, which includes faster bypassing of Face ID to the passcode unlock screen if the user is wearing a mask due to COVID-19 safety requirements.
