Unconsciously, iOS is the ninth generation. With the development of iPhone, iOS has also added many functions. We will probably see iOS 10 on Apple's WWDC this year. So Sam Beckett, a foreign visual designer, specially made a concept video for him, and the name was also changed from iOS X to OS X, another system of Apple.
iOS 10 Concept
This concept video focuses on the improvement of the control center, which can be edited by pressing and holding the button; The 3D Touch function is further enhanced and can also be used in the control center; Night mode is added, which is closer to user habits.
IOS 10 should be introduced during WWDC 2016. At present, Apple has not announced the date, which may be from June 13 to June 17, and should be before this autumn at the latest. I wonder if Sam Beckett's guess will come true?
