you could use an async library to download and set image: https://github.com/onevcat/Kingfisher or https://github.com/rs/SDWebImage — Mohammad Zaid Pathan, Dec 19 '16 at 10:32

Alamofire.download("https://httpbin.org/image/png").responseData { response in
    if let data = response.result.value {
        let image = UIImage(data: data)
        self.view.backgroundColor = UIColor.init(patternImage: UIImage.init(CGImage: image.CGImage!))

    }
}

Directly you can't set image to UIView. First you need to set image to ImageView and add that ImageView as addSubView to UIView. If you want to load image asynchronously(for better performance), you can use Alamofire's code like below.

Alamofire.download("https://httpbin.org/image/png").responseData { response in
   if let data = response.result.value {
      let image = UIImage(data: data)
   }
}

No way we can set image to UIView. Pass url.absoluteString as an argument to that method – Sivajee Battina Dec 19 '16 at 10:45

This work for me

 let url = NSURL(string: "https://httpbin.org/image/png")
    let data = NSData(contentsOfURL: url!)
    let image = UIImage(data: data!)
    self.view.layer.contents = image?.CGImage
