There are two ViewController in this app

ViewController1 --> Present As Popover --> ViewController2

In ViewController2, it set Background to Black Color, and Alpha to 0.1

When the transition of ViewController2 is finish, background will become 1 alpha

How to keep Background of ViewController2 0.1?

  • that is a [good material from Apple](https://developer.apple.com/documentation/uikit/uimodalpresentationstyle/1621382-popover) to understand popover-presentation-style... briefly: _"In a horizontally compact environment [a.k.a portrait iPhone], this option behaves the same as `fullScreen`."_ – holex Dec 13 '17 at 12:55

If you present a vie controller modally and gives background colour to clear then it will be transparent until u give some color. 

    self.present(viewController2, animated: true, completion: nil)
