Introduction to the iOS system

iOS is a mobile operating system developed by Apple. Apple first announced this system at the Macworld conference on January 9, 2007. It was originally designed for iPhone, and was later applied to iPod touch and iPad. iOS is the same as Apple's macOS operating system.

It is a Unix-like commercial operating system. Originally this system was called iPhone OS. Because iPad, iPhone, and iPod touch all use iPhone OS, it was announced at WWDC in 2010 that it would be renamed to iOS (iOS is a registered trademark of the network equipment operating system of the American company Cisco, and Apple's name change has been authorized by Cisco) .

In January 2016, with the release of iOS 9.2.1, Apple fixed a vulnerability that had existed for 3 years. On September 22, 2018, Apple in the United States secretly added a "trust rating" function based on iPhone users and other device users of the company in its latest operating system.

According to reports on November 17, 2021, Apple’s iOS 15.2 Beta leaked the new “SportsKit” framework. On January 28, 2022, Apple pushed the iOS/iPadOS 15.4 developer preview beta update to iPhone and iPad users. This update was 2 weeks after the last release.
