            |

            | 
            | 
           186 | 
           4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project.

            | 
            | 
           227 | 
           Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
  | 
        
        
            | 
            | 
           228 | 
           In order to actually test receiving push notifications, you will need to:
  | 
        
        
            | 
            | 
           229 |

            | 
            | 
           230 | 
           1. Change the bundle identifier of the sample app to something you own in your Apple Developer
  | 
        
        
            | 
            |

           account, and enable that App ID for push notifications.
  | 
        
        
            | 
            | 
           232 | 
           2. You'll also need to

            | 
            | 
           233 | 
           [upload your APNs Provider Authentication Key or certificate to the

           3. Ensure your iOS device is added to your Apple Developer portal as a test device.
  | 
        
        
            | 
            |

            | 
            | 
           240 | 
           The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
  | 
        
        
            | 
            | 
           241 | 
           In order to receive push notifications, you'll have to follow the steps above and run the app on a
  | 
        
        
            | 
            |
