Here it is in Swift 4/5

    func copyDatabaseIfNeeded(sourcePath : String) -> Bool {
      var destPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!
      destPath = destPath + "/foo.db3"
      let databaseExistsWhereNeeded = FileManager.default.fileExists(atPath: destPath)
      if (!databaseExistsWhereNeeded) {
        do {
            try FileManager.default.copyItem(atPath: sourcePath, toPath: destPath)
            print("db copied")
        }
        catch {
            print("error during file copy: \(error)")
        }
    }
    return true
}
