No se puede ejecutar RealTimeRoom Google-Play-Games iOS ButtonClicker2000 muestra en dispositivo real

Estoy tratando de ejecutar el proyecto ButtonClicker2000 de ejemplo de Google-Play-Games para iOS enReal Dispositivo. (Inicio rápido:https://developers.google.com/games/services/ios/quickstart
descargas:https://developers.google.com/games/services/downloads/)

El proceso de inicio de sesión en GooglePlayService no muestra ningún error.
Estoy seguro de que mi proyecto de la consola de Google se configuró correctamente.
No tengo ningún problema al iniciar el emulador

PERO en un dispositivo real (no importa en iphone o ipad) cuando hago clic en el botón de coincidencia rápida, aparece este error (en la parte inferior):
