Answer 1

Swift 4.2 and AlamofireImage

If using a library is not an issue, you can do it by help of the AlamofireImage. my samples are from its Github

Placeholder Images Example:

let imageView = UIImageView(frame: frame)
let url = URL(string: "https://httpbin.org/image/png")!
let placeholderImage = UIImage(named: "placeholder")!
imageView.af_setImage(withURL: url, placeholderImage: placeholderImage)

it has many handy functions and extension to work with images. from caching to scaling and resizing or even applying filters on the image. if images are important in your app, I suggest to use this framework and save your time.
