I am currently using an API to query some information and am getting back a JSON string. I’ve looked around but am unable to get the string into a dictionary. Thoughts?

let url = URL(string: "https://api.spoonacular.com/food/products/upc/041631000564?apiKey=xxx")!
let task = URLSession.shared.dataTask(with: url) {(data, response, error) in
  guard let data = data else { return }
  let str = String(data: data, encoding: .utf8)!
  print(str)

}

task.resume()

The string printed:
