title: RingCentral: Build Failed Task failed with exit code 65: Carthage installation
body: <p>I have a project that was build in Xcode9.
  Now I am updating it to Xcode10.
  I am using RingCentral iOS SDK.</p>
  
  <p>But whenever I update the SDK, it shows this error:
  I have tried almost all methods for cleaning and building derived data</p>
  
  <p>Carthage version = 0.32.0</p>
  
  <p>Xcode version = 10.1</p>
  
  <p>Please help, I am stuck and cannot run the project</p>
