Swift 3: Display Image from URL

Question

In Swift 3, I am trying to capture an image from the internet, and have these lines of code:

var catPictureURL = NSURL(fileURLWithPath: \"http://i.imgur.com/         


        

Answer 1

Swift

Good solution to extend native functionality by extensions

import UIKit
    
extension UIImage {
  convenience init?(url: URL?) {
    guard let url = url else { return nil }
            
    do {
      self.init(data: try Data(contentsOf: url))
    } catch {
      print("Cannot load image from url: \(url) with error: \(error)")
      return nil
    }
  }
}

Usage

Convenience initializer is failable and accepts optional URL – approach is safe.

imageView.image = UIImage(url: URL(string: "some_url.png"))
