Add background image to UIView

UIView+backgroundImage.swift

import UIKit

extension UIView {
	func backgroundImage(named: String) {
		let backgroundImage = UIImageView(frame: self.frame)
		backgroundImage.image = UIImage(named: named)
		backgroundImage.contentMode = .scaleAspectFill
		backgroundImage.translatesAutoresizingMaskIntoConstraints = false
		backgroundImage.center = self.center
		backgroundImage.autoresizingMask = [.flexibleLeftMargin, .flexibleRightMargin, .flexibleTopMargin, .flexibleBottomMargin]

		self.insertSubview(backgroundImage, at: 0)
		self.sendSubview(toBack: backgroundImage)
	}
}

Thanks!
