swift 5.0 update

Minor update to swift 5.0 settings

First Release

UIPopoverBackgroundView replacement for iOS that allows fullscreen and background fadein animation.

The PopoverBackgroundConditioner allows you to set the arrow size(defualt CGSize(width: 20, height: 10)), popover insets(defualt: UIEdgeInsets(top: -30, left: -10, bottom: -10, right: -10), allows for popover to use fullscreen), arrow color(defualt clear).

The PopoverBackgroundView sets it self as the currentBackground in the PopoverBackgroundConditioner. This allows you to proform animation on it later, such as fade in or change color
