Desativar o log de depuração do Google App Measurement

No Xcode 7.2, como posso desabilitar essas medições de depuração / aplicativo em exibições não econômicas:

2016-01-07 11:52:53.085 MyApp[1457:] <GMR/INFO> App measurement v.1302000 started
2016-01-07 11:52:53.091 MyApp[1457:] <GMR/INFO> To enable debug logging set the following application argument: -GMRDebugEnabled (see http://goo.gl/Y0Yjwu)

2016-01-07 11:52:53.092 MyApp[1457:] <GMR/DEBUG> App measurement is monitoring the network status

Me incomoda há algum tempo ...

Obrigado !

Edit: Eu tentei o -noGMRDebugEnabled flag, reinstalando o aplicativo sem -GMRDebugEnabled, redefina o conteúdo e as configurações, reiniciando o Xcode ... nada funciona :-(
