Swifui print value of data in response - swift

Question

I am using a post API method like this
AF.request("http://40.86.255.119/api/Authentication", method:.post, parameters: parameters,encoding: JSONEncoding.default) .responseJSON { (response) in
print(response)
}
It's showing me a response
success({
data = {
security = (
);
token = "eyJhbGc";
};
key = "<null>";
message = "Login Successfully";
succeed = 1;
})
I need to print just a token of data and need to know how can I do this?

I try to like this but the issue is how ill show token that is inside the data array. It's showing a message which is outside an array but the token is inside an array.
AF.request("http://40.86.255.119/api/Authentication", method: .post, parameters: parameters, encoding: JSONEncoding.default)
.responseJSON { response in
switch response.result {
case .success(let value):
if let json = value as? [String: Any] {
print(json)
print(json["message"]) //this work
print(json["data"]["token"]) //this didnt work
}
case .failure(let error):
print(error)
}
}

I highly recommend to take advantage of the JSON decoding capabilities of AF.
Create two structs
struct Response : Decodable { let data : TokenData }
struct TokenData : Decodable { let token : String }
And replace .responseJSON with .responseDecodable and an appropriate type annotation of response.
In any case you should handle the potential error
AF.request("http://40.86.255.119/api/Authentication", method:.post, parameters: parameters) .responseDecodable { (response : DataResponse<Response,AFError>) in
switch response.result {
case .success(let result): print(result.data.token)
case .failure(let error): print(error)
}
}
