Answer 1

After changing the Json to this format:

{"1":2,"2":27,...}

Change the loop to:

    for i in 1 ... 20 {
        if let value = jsonval["\(i)"] as? Int {
            num.append(value)
            print(value)
        }
    }

Then you will have the array with elements from Json, and print them by the way.
