I make POST request to the server from my app, and I get jsonString as the response. I have made function to convert string to dictionary which looks like this: 

```
    func convertStringToDictionary(text: String) -> [String:AnyObject]? {
    if let data = text.dataUsingEncoding(NSUTF8StringEncoding) {
        do {
            return try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String:AnyObject]
        } catch let error as NSError {
            print(error)
        }
    }
    return nil
}

```

after getting the response from the server I convert the string to dictionary by function and then I want to check if user is logged in: 

```
       let result = convertStringToDictionary(jsonString as String)

        if (result!["loggedIn"] == "1")
        {
            print("You are logged in!")
        }

```

And then I get the error "Cannot convert value of type AnyObject? to expected argument String". I suppose I have to convert variable of type AnyObject to String if i want to compare it to string. I have tried every option which I have found on the Google but I havent got it to work.
