Simple way to make default navigation bar transparent.

Just add these line to your AppDelegate class's didFinishLaunchingWithOptions function.

var imageForDefault = self.imageWithColor(UIColor(red: 0.0, green: 0.0, blue: 0.0, alpha: 0.0))
var imageForCompact = self.imageWithColor(UIColor(red: 0.0, green: 0.0, blue: 0.0, alpha: 0.0)) 
UINavigationBar.appearance().setBackgroundImage(imageForDefault, forBarMetrics: UIBarMetrics.Default) 
UINavigationBar.appearance().setBackgroundImage(imageForCompact, forBarMetrics: UIBarMetrics.Compact)

func imageWithColor(color: UIColor) -&gt; UIImage{
	let rect:CGRect = CGRectMake(0, 0, 1, 1);
	UIGraphicsBeginImageContextWithOptions(rect.size, false, 0);
	color.setFill()
	UIRectFill(rect)
	let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()
	return image;
}
