Remove Border of UISearchBar in iOS7

Question

I\'m trying to remove border of UISearchBar in iOS 7. In iOS 6 it\'s working fine. I created the UISearchBar programatically. I tried almost every thing from Stack Overflow

Answer 1

Okay. There are so many answers, but they are too complex. I've found this solution:

Swift 3 (4)

searchBar.setBackgroundImage(UIImage(), for: .top, barMetrics: .default)
searchBar.backgroundColor = .primary

Where .primary is

extension UIColor {

    static var primary:UIColor {
        return "#5163F4".color
    }
}
