Parsing using decodable when value of a dictionary is an array of strings

Question

I want to parse the json file below, but I keep getting the following error:

typeMismatch(Swift.Array, Swift.DecodingError.Context(codingPath: [], debugDescription: "Expected to decode Array but found a dictionary instead.", underlyingError: nil))

I have looked on stackoverflow, but they didn't seem to help as I don't see other json files that returns a dictionary value that is an array of strings. Any ideas?

//JSON file
{
 pugs: [
   "http://27.media.tumblr.com/tumblr_lqfwfyZuyS1qiyqyfo1_500.jpg",
   "http://30.media.tumblr.com/tumblr_liic7bdmRF1qcipjro1_500.jpg",

   "http://27.media.tumblr.com/tumblr_liy1xfY9G71qftdfxo1_500.jpg"
  ]
}

//Data Model
class PugList: Codable {
    var pugs: [Pug]
    var likes: Int
}

class Pug: Codable {
    var images: [String]
}

Btw, json which you've showed isn't valid... you're probably missing ] — Robert Dresler

@RobertDresler thanks for catching that. I didn't post the entire array and was missing the closing bracket. — mir

You don't need the Pug class. Change pugs to [String].

BTW - use struct instead of class unless you have a good reason to use a class.
