title: Use different GoogleService-Info.plist for different build schemes
body: <p>I am using a build scheme for prod and one for staging (with 2 different bundle identifiers) and I am trying to use a separate GoogleService-Info.plist for each scheme.
  Is there any way to manually select the plist file to use when initialising GCM (and goole login)? Or is its possible to avoid using the plist and do the setup manually?</p>
  
  <p>Thanks!</p>
