Swift 5 version:

extension UIView {
    func snapshot() -> UIImage? {
        UIGraphicsBeginImageContextWithOptions(self.bounds.size, true, UIScreen.main.scale)
        self.layer.render(in: UIGraphicsGetCurrentContext()!)
        let img = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return img
    }
}

More safe approach (without force unwrap).

extension UIView {

    func snapshot() -> UIImage? {
        UIGraphicsBeginImageContextWithOptions(bounds.size, true, UIScreen.main.scale)

        guard let currentContext = UIGraphicsGetCurrentContext() else {
            UIGraphicsEndImageContext()
            return nil
        }

        layer.render(in: currentContext)

        let image = UIGraphicsGetImageFromCurrentImageContext()

        UIGraphicsEndImageContext()

        return image
    }
}
