responseJSON json parse in Alamofire

I am getting json form server. But json parsing nil in swift. Here is my json

{
    "out_code":"0",
    "out_message":"0",
}

I tried bellow code to out_code using Alamofire & swiftjson

func getData(){
    
    Alamofire.request("url", method: .post,parameters: [
        "request_code":"11"
        
    ]).responseJSON{(responseData) -> Void in
        if((responseData.result.value != nil)){
            
            let swiftyJsonVar = JSON(responseData.result.value!)
            print("swiftyJsonVar==",swiftyJsonVar)
            
            if let v_id = swiftyJsonVar["out_code"] as? String {
                print("out_code----",v_id)
            }
            
        }
    }
}

swiftyJsonVar== in print like bellow

{
    "out_code" : "0",
    "out_message" : null
}

But I did not get data from out_code key. Please help me what is wrong with my code...

Apparently you are using SwiftyJSON library.

Casting for each type is been handled from the library. Try using the following code instead of casting to String:

if let v_id = swiftyJsonVar["out_code"].string {
    print("out_code----",v_id)
}
