  // This is a trick to force generate a `FirebaseDatabase-Swift.h`
  // header that re-exports `FirebaseDatabaseInternal` for Objective-C
  // clients. It is important for the below code to reference a Database
  // symbol defined in Objective-C as that will import the symbol's
  // module (`FirebaseDatabaseInternal`) in the generated header. This
  // allows Objective-C clients to import Database's Objective-C API
  // using `@import FirebaseDatabase;`. This API is not needed for Swift
  // clients and is therefore unavailable in a Swift context.
