title: iOS Simulator deployment target set to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99
body: <p>Am working on a completely new project. Just created it two days ago and am having issues when I am trying to build and run it on the IOS Simulator. Here is the message:</p>
  <p>The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99. (in target 'gRPC-C++' from project 'Pods')</p>
  <p>Strangest thing is that I also created a new project for another app last week and didn't get this issue.</p>
  <p>Any help in solving this would be really appreciated.</p>
  <p>Many thanks</p>
