Leo Dabus's answer is awesome! I just wanted to provide an all-in-one function solution:

let url = URL(string: 
    "http://www.apple.com/euro/ios/ios8/a/generic/images/og.png")

let task = URLSession.shared.dataTask(with: url!) { data, response, error in
    guard let data = data, error == nil else { return }

    DispatchQueue.main.async() {    // execute on main thread
        self.imageView.image = UIImage(data: data)
    }
}

task.resume()
