Answer 1

More than likely that JSON response you posted will eventually find its way to you in the form of a key-value Dictionary. You then use a "key" from the JSON you posted to extract the key's corresponding "value". In the snippet you posted, the keys would be the values on the left of the colon (eg "product_id", "name", etc).

Now, lets say your dictionary of key-values was called "jsonDictionary". You then would extract the values like so:

let productId = jsonDictionary["product_id"]
let name = jsonDictionary["name"]

If, however, you don't have logic to deserialize that raw JSON data (that you posted in your question) into a Dictionary, then you'll have to start there instead.

You have to use like this :

for product in products {
    if let productImages = product["images"], let images = productImages as? NSArray {
        for image in images {
            if let image = image as? [String: String] {
                print(image["image"])
            }
        }
    }
}
