I have made a mistake which I can't find. The array (class level) gets empty just before returning it. 

```
private func loadUserData() {
    // We're getting user info data from JSON response
    let session = Twitter.sharedInstance().sessionStore.session()
    let client = TWTRAPIClient.withCurrentUser()
    let userInfoURL = "https://api.twitter.com/1.1/users/show.json"
    let params = ["user_id": session?.userID]
    var clientError : NSError?
    let request = client.urlRequest(withMethod: "GET", url: userInfoURL, parameters: params, error: &clientError)
    client.sendTwitterRequest(request) { (response, data, connectionError) -> Void in
        if connectionError != nil {
            print("Error: \(connectionError)")
        }

        do {
            let json = JSON(data: data!)
            if let userName = json["name"].string,
                let description = json["description"].string,
                let followersCount = json["followers_count"].int,
                let favouritesCount = json["favourites_count"].int,
                let followingCount = json["friends_count"].int,
                let lang = json["lang"].string,
                let nickname = json["screen_name"].string {

                self.userData.append(userName)
                self.userData.append(description)
                self.userData.append(String(followersCount))
                self.userData.append(String(favouritesCount))
                self.userData.append(String(followingCount))
                self.userData.append(lang)
                self.userData.append(nickname)
                print(self.userData)
            }

        }
    }
    print(userData)
}

```

I'm just trying to access to its values from other part of the code and can't do it as it gets empty. I can see the array data the first time I print it, but not in the second one.
Thank you very much!
