Not able to receive OpenIDClaim and accesstoken in iOS 9.3 with AeroGearOAuth2

I configured keycloak and iOS app I am able to connect with iOS app to keycloak. (Oauth2.0 aerogear SDK and keycloak 1.9.3)
After successful login safari browser redirects to app where I should be able to get access token.
response comes as nil in login call back method.
Below is the code which I run
let keycloakConfig = Config(base: "http://kc.dev.com:8080", authzEndpoint: "auth/realms/SharedServices/protocol/openid-connect/auth", redirectURL:"fcapp:/", accessTokenEndpoint: "/auth/realms/SharedServices/protocol/openid-connect/token", clientId: "Mobile",
refreshTokenEndpoint: "/auth/realms/SharedServices/protocol/openid-connect/token/refresh",
revokeTokenEndpoint: "/auth/realms/SharedServices/protocol/openid-connect/token/revoke"

)
keycloakConfig.isWebView = false

let http = Http()
var gdModule = AccountManager.addAccount(keycloakConfig, moduleClass: KeycloakOAuth2Module.self)
// gdModule = KeycloakOAuth2Module(config: keycloakConfig, session: UntrustedMemoryOAuth2Session(accountId: "ACCOUNT_FOR_CLIENTID_(keycloakConfig.clientId)"))
http.authzModule = gdModule

gdModule.login {(accessToken: AnyObject?, claims: OpenIDClaim?, error: NSError?) in

print(accessToken) // Comes nil how can I get access token??
print(claims?.description) // Comes nil
print(error) // comes as errorcode =0
self.userInfo = claims
if let userInfo = claims {
if let name = userInfo.name

{ print(name) }

}

}
