Swift - response view in every view? - ios

Question

I've got a small question: is it possible somehow (without storyboard) to create a little view at the top of the screen (if there's a navigationbar, then under that), that displays errors / responses if needed?
Without creating views on every single viewController I made, just by code?
Or is there some extension you could recommend?
For example: "No Internet Connection"

Code required
extension UIViewController
{
func showNotificationView(message : String)
{
//base View
let baseView = UIView(frame: CGRect(x: 20, y: self.view.frame.size.height-(self.view.frame.size.height*0.15), width: self.view.frame.size.width-40, height: self.view.frame.size.height*0.08))
baseView.backgroundColor = UIColor.gray
baseView.clipsToBounds=true
self.view.addSubview(baseView)
//Image View
let imageView = UIImageView(image: UIImage(named: "RM_3"))
imageView.clipsToBounds=true
imageView.frame = CGRect(x: 0, y: 0, width: baseView.frame.size.width*0.2, height: baseView.frame.size.height)
baseView.addSubview(imageView)
//Label
let textLabel = UILabel(frame: CGRect(x: baseView.frame.size.width*0.2+10, y: 0, width: baseView.frame.size.width, height: baseView.frame.size.height))
textLabel.textColor = UIColor.white
textLabel.backgroundColor = UIColor.clear
textLabel.textAlignment = .left;
textLabel.numberOfLines = 0
textLabel.font = UIFont(name: "Montserrat-Light", size: 12.0)
textLabel.text = message
baseView.addSubview(textLabel)
}
}
Usage
#IBAction func navigate(_ sender: Any) {
self.showNotificationView(message: "hihihihh")
}
