Answer 1

Works with Swift 2:

            let tabController = UIApplication.sharedApplication().windows.first?.rootViewController as? UITabBarController
            let tabArray = tabController!.tabBar.items as NSArray!
            let alertTabItem = tabArray.objectAtIndex(2) as! UITabBarItem


            if let badgeValue = (alertTabItem.badgeValue) {
                let intValue = Int(badgeValue)
                alertTabItem.badgeValue = (intValue! + 1).description
                print(intValue)
            } else {
                alertTabItem.badgeValue = "1"
            }
