When iOS 7 was introduced by Jonathan Ive, the revolution with flat graphical user interfaces exploded. Now iOS 10 represents mature form of mobile minimalistic UI. It is simple but also a lot more readable and understandable for the users than previous versions. When you prepare design for one of devices’ that run Apple’s iOS you should follow it’s guidelines. Off course as I mentioned in the article about Material Design do not start from scratch – use UIKits and icon templates to create UI faster.
