In iOS 13, Apple changed the volume up indicator. It began to look like a small strip on the left instead of a square that appeared in the middle of the screen.
In addition, in iOS 13 there were dynamic wallpapers that change depending on the time of day as on macOS Mojave. The developers also found support for two audio streams with different loudness.
iOS 13 was presented on June 3 at WWDC 2019. The system received for the first time a “dark” theme, svaypas in a standard keyboard, redesigned system applications and more.
