unable to extract value from struct using swift JSON Decoder

Question

Please tell me the way to extract the value of "ranking". Check the image first.

My struct :

struct Result2 : Codable{
    let rankings : [Myrankings3]

    struct Myrankings3 : Codable{
        let ranking : String
    }
}

JSON code

do {
    let finalResult = try JSONDecoder().decode(Result2.self, from: data!)
    print(finalResult)        
    // I want to get the value of ranking which is of type string 
}

Welcome to Stackoverflow. Please don't post images. Post the JSON as text. — vadian, Dec 12 '17 at 19:08

In the root object (finalResult) iterate the array rankings

let finalResult = try JSONDecoder().decode(Result2.self, from: data!)
for myRanking in finalResult.rankings {
      print(myRanking.ranking)
}
