Please try this one it is working on swift 3.0

func copyDatabaseIfNeeded() {
    //Using NSFileManager we can perform many file system operations.
    let fileManager = FileManager.default
    let error: Error?
    let dbPath: String = self.getDBPath()
    var success: Bool = fileManager.fileExists(atPath: dbPath)
    if !success {
        let defaultDBPath: String = URL(fileURLWithPath: (Bundle.main.resourcePath)!).appendingPathComponent("database.sqlite").absoluteString

        do {
            success = try fileManager.copyItem(atPath: defaultDBPath, toPath: dbPath) as Any as! Bool
        }
        catch let error as NSError {
            print("Ooops! Something went wrong: \(error)")
        }

        if !success {
            assert(false, "Failed to create writable database file with message '\(error?.localizedDescription)'.")
        }
    }
}

func getDBPath() -> String {
    let paths: [Any] = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
    let documentsDir: String = paths[0] as! String
    return URL(fileURLWithPath: documentsDir).appendingPathComponent("database.sqlite").absoluteString
}
