I am trying to save all names from a json url to a list but it doesn’t work.

I am using this code:

let jsonUrl = ("https://de1.api.radio-browser.info/json/stations/byname/jazz")
Alamofire.request( jsonUrl).responseJSON { (responseData) -> Void in
    if((responseData.result.value) != nil) {
        
        let swiftyJsonVar = JSON(responseData.result.value!)
        
        for (_, subJson):(String, JSON) in swiftyJsonVar {
            
            for (_, subJson):(String, JSON) in subJson {
                
                let nameList = subJson["name"].stringValue
                print(nameList)
            }
        }
    }
}

What can I do to fix it?
