How to make a View controller overlay in Xcode, like in VK?

Question

iOS

Hello dear developers!
I would like to make sure that when swiping from left to right, the panel does not completely go away, but a small "gap" remains. So that later you can select either another tab, or check the number of messages ... It doesn't matter.
And I would like to add depth to the block on the left, a slight blur and more shadow...
