For apple, it's trying everything to get more users to upgrade to the latest IOS system.
Apple's Apple Store IOS client application ushered in the V5.6 update, and the update log is still a variety of improvements and performance enhancements. It is not mentioned to adapt to the new IOS 13 system, because it cannot follow the dark mode. However, the update also shows that Apple's own app does not support IOS 11.
In addition, Apple released the IOS 13.2.2 update today, and also updated the version number of the available system version. Currently, only IOS 13.2 and above can be used.
IOS 13.2 is the current public version of IOS, which brings support for airpods pro, including new emoticons, and adds deep fusion and other important functions for iPhone 11 and 11 pro.
This week Apple also released the first public beta of IOS 13.3, an upcoming update that introduces "screen time communication restrictions.".
