var navBarColor = UIColor (red:0.161,green:0.18,blue:0.247,alpha:1.0)
UINavigationBar.appearance().barTintColor = navBarColor

Answer 1

You can create your own custom hex extension to accomplish this fairly easily. For instance something like this may work:

extension UIColor {
     convenience init(hex: Int) {
            let r = hex / 0x10000
            let g = (hex - r*0x10000) / 0x100
            let b = hex - r*0x10000 - g*0x100
            self.init(red: CGFloat(r)/255, green: CGFloat(g)/255, blue: CGFloat(b)/255, alpha: 1)
        }
}

Then you can call it like:

UINavigationBar.appearance().barTintColor = UIColor(hex: 0x292e3f)

To get the hex color you want.
