Popover dismiss click outside iOS swift

Problem: 

I want to dismiss the view while tap on outside of the view after popover presented.How can i achieve that?

Solution:

    func popoverPresentationControllerShouldDismissPopover(_ popoverPresentationController: UIPopoverPresentationController) -> Bool {

        return true

    }

Add the above function in your viewcontroller with popover delegate.
