If you got the reference to the tabBarController (e.g. from the UIViewController) you can do the following:

if let tabItems = tabBarController?.tabBar.items {
    // In this case we want to modify the badge number of the third tab:
    let tabItem = tabItems[2]
    tabItem.badgeValue = "1"
}

From a UITabBarController it would be tabBar.items instead of tabBarController?.tabBar.items

and to delete the badge: 

tabItem.badgeValue = nil
