[ogezue]

When I use you lib I get a lot of debug statements in the console

"/Pods/PopoverSwift/PopoverSwift/Sources/PopoverItem.swift:46:PopoverItem:deinit"
"/Pods/PopoverSwift/PopoverSwift/Sources/PopoverView.swift:275:PopoverView:deinit"
"/Pods/PopoverSwift/PopoverSwift/Sources/PopoverItem.swift:46:PopoverItem:deinit"
"/Pods/PopoverSwift/PopoverSwift/Sources/PopoverItem.swift:46:PopoverItem:deinit"
"/Pods/PopoverSwift/PopoverSwift/Sources/PopoverCell.swift:168:PopoverWihtImageCell:deinit"
"/Pods/PopoverSwift/PopoverSwift/Sources/PopoverCell.swift:168:PopoverWihtImageCell:deinit"
