Solve error Xcode 7.3 or later in required in Xamarin MacOS

Suddenly, we got this error en our Xamarin Project :"Automatic Provisioning failed: This request is forbidden for security reasons: Authentication Error. Xcode 7.3 or later is required to continue developing with your Apple ID" I have read in many forums that it is a Microsoft problem, but it has not been solved yet. I have tried a couple of solutions but they have not worked. We need someone to help us solve the problem. ************************************************************* De pronto, tenemos el siguiente error en nuestro proyecto de Xamarin: "We need someone to help us solve the problem.". He leido en varios foros que el problema es de Microsoft, pero aparentemente no le han dado solución aún. He tratado con algunas soluciones pero no han funcionado. Necesitamos a alguien que nos ayude a resolver el problema.
