How to pass parameter in swift controller to objective c model? - objective-c

Question

I couldn't figure out on how to pass variables with type String in swift controller files and pass it to object written in objective-c. However, if I pass a string directly as a parameter it works just fine. Thank you for your help.
This is the objective-c class below
#import "Message.h"
#implementation Message
- (instancetype)initWithDictionary:(NSDictionary *)dictionary
{
self = [super init];
if (self)
{
self.userID = dictionary[#"user_id"];
self.username = dictionary[#"username"];
self.avatarURL = dictionary[#"avatar_url"];
self.text = dictionary[#"message"];
}
return self;
}
- (instancetype)initWithTestName:(NSString *)name withTestMessage:(NSString *)message withUserId:(NSString *)userId withAvatarUrl:(NSString *)url
{
self = [super init];
if (self)
{
self.userID = userId;
self.username = name;
self.avatarURL = url;
self.text = message;
}
return self;
}
#end
and this is the swift controller file
import UIKit
class ChatViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
private var messages = [Message]()
override func viewDidLoad() {
super.viewDidLoad()
// I can pass the string successfully to the messages this way
messages.append(Message(testName: "Test", withTestMessage: "Hello", withUserId: "1", withAvatarUrl: "http://www.example.com"))
// After successfully making Api Request, I wasn't able to pass a variable as parameter
if let data = dic as? [String:Any]{
let userId = data["user_id"] as? String
let url = data["avatar_url"] as? String
let name = data["name"] as? String
let message = data["message"] as? String
self.messages.append(Message(testName: name, withTestMessage: message, withUserId: userId, withAvatarUrl: url))
}
}
}
