Answer 1

Add this code in viewDidLoad

DispatchQueue.main.async {
            let size = CGSize(width: self.tabBar.frame.width / numberOfTabsFloat,
                              height: self.tabBar.frame.height)
            let image = UIImage.drawTabBarIndicator(color: UIColor.white,
                                                   size: size,
                                                   onTop: false)
            UITabBar.appearance().selectionIndicatorImage = image
            self.tabBar.selectionIndicatorImage = image
        }

and add this extension

extension UIImage{
    //Draws the top indicator by making image with filling color
    class func drawTabBarIndicator(color: UIColor, size: CGSize, onTop: Bool) -> UIImage {
        let indicatorHeight = size.height
        let yPosition = onTop ? 0 : (size.height - indicatorHeight)

        UIGraphicsBeginImageContextWithOptions(size, false, 0)
        color.setFill()
        UIRectFill(CGRect(x: 0, y: yPosition, width: size.width, height: indicatorHeight))
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return image!
    }
}
