UIImage from UIView extension

uiview-extensions.swift

import UIKit

extension UIView {
    
    func createImage() -> UIImage {

        let rect: CGRect = self.frame
        
        UIGraphicsBeginImageContext(rect.size)
        let context: CGContextRef = UIGraphicsGetCurrentContext()
        self.layer.renderInContext(context)
        let img = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        
        return img

    }
    
}

  if #available(iOS 10.0, *) {
            let renderer = UIGraphicsImageRenderer(bounds: bounds)
            return renderer.image { rendererContext in
                layer.render(in: rendererContext.cgContext)
