Twitter SDK ios with Fabric

Question

I need to implement twitter login in my iOS app, I have installed twitter framework with fabric SDK. Now for the very first time I am facing the issue while loggin in. I can able to receive the token details

Twitter Details :@TestUserApp logged in! (796637020760186880)

Auth token:796637020760186880-ieeZM2Mbn3FLutLOcJ1sk7bp83ZSlzU

Auth Token secret:1G0O5YdF89V0VtoNmdY8W3ui2pkPNvKgtNPbqrleOiIoB

Error : Error Domain=TwitterAPIErrorDomain Code=99 "Request failed: forbidden (403)" UserInfo={NSLocalizedFailureReason=Twitter API error : Unable to verify your credentials (code 99), TWTRNetworkingStatusCode=403, NSErrorFailingURLKey=https://api.twitter.com/oauth2/token, NSLocalizedDescription=Request failed: forbidden (403)}

Full Code:

TWTRLogInButton *logInButton = [TWTRLogInButton buttonWithLogInCompletion:^(TWTRSession *session, NSError *error) {
    if (session) {

        NSString *authToken = session.authToken;
        NSString *authTokenSecret = session.authTokenSecret;
        NSString* userId = session.userID;
        NSString *message = [NSString stringWithFormat:@"@%@ logged in! (%@) -Auth token:%@ -Auth Token secret:%@",
                             [session userName], [session userID],authToken,authTokenSecret];

        // Objective-C
        TWTRAPIClient *client = [[TWTRAPIClient alloc] init];
        [client loadUserWithID:userId completion:^(TWTRUser *user, NSError *error) {
            if (error == nil) {
                 NSLog(@"Name:%@ -- ScreenName:%@ -- ProfileImageUrl:%@",user.name,user.screenName,user.profileImageURL);
            }
            else {
                NSLog(@"Error:%@",error.description);
            }

        }];

    } else {
        NSLog(@"Login error: %@", [error localizedDescription]);
    }
}];
