JSON parsing rapid api swift corrupted data - json

Question

I’m trying to parse json to find Music Info from tiktok song by Id to play in app, can’t proper make a model to get data. Model that I made with quicktape.io not working. Can someone help me? Here is the link to api https://rapidapi.com/h0p3rwe/api/tiktok-all-in-one
Song id I get by this api: https://ontrend.ai/api/v1/trend/music?type=all , this one is ok. Problem only with rapidapi
This is my request:
func fetch(){
let headers = [ "X-RapidAPI-Key": "0a5efc1659mshadcf7e7123f8554p1e0527jsn74096e7ef6dd",
"X-RapidAPI-Host": "tiktok-info.p.rapidapi.com" ]
let musicURL = "https://tiktok-info.p.rapidapi.com/music/6661867221164821250"
let request = NSMutableURLRequest(url: NSURL(string: musicURL)! as URL,cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "GET"
request.allHTTPHeaderFields = headers
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest){
[weak self] data, _ , error in
guard let data = data, error == nil else{
return
}
do{
let songId = try JSONDecoder().decode(MusicSongModel.self, from: data)
DispatchQueue.main.async { [self] in
print(songId)
}
}
catch{
print(error)
}
}
dataTask.resume()
}
and this is model:

latest time when I try to fetch this code worked for me, but [String : Any] only. Now its too much of request/per day passed
func fetchSong() {
let headers = [

request.httpMethod = "GET"
request.allHTTPHeaderFields = headers

Maybe some know good working api for play music by id? And good model data

Answer 1

The answer is:
public func getMusicLink(completion: #escaping (String) -> (), id : String) {
manager.request("https://tiktok-all-in-one.p.rapidapi.com/music?id=\(id)", method: .get, headers: headers).responseJSON { response in
if (response.value != nil) {
let reponseData = response.value as! [String: Any]
let musicInfo = reponseData["music_info"] as! [String:Any]
let playUrls = musicInfo["play_url"] as! [String:Any]
let playUrl = playUrls["uri"] as! String
completion(playUrl)
}
}
}
