Swift 如何使用Theo将neo4j桌面数据库连接到ios应用程序

我正在尝试将我的iOS应用程序与theo框架连接到我的桌面neo4j数据库

因此，我在Xcode中添加了Theo作为依赖项，并尝试运行以下代码：

import SwiftUI
import Theo

@main
struct MyApp: App {
  
    let client = try! BoltClient(hostname: "localhost", port: 7687, username: "neo4j", password: "myPassword", encrypted: false)

    
    var body: some Scene {
        WindowGroup {
            Button(action: {
               client.connect(completionBlock: { error in
                    print("ups something went wrong: \(error)")
                })
            }){
                Text("create Node")
            }
        }
    }
}

我希望当你按下按钮时，你能连接到数据库。但事实并非如此，我收到以下错误消息：

2021-04-08 16:57:27.764293+0200 MyApp[9426:283393] [] nw_protocol_get_quic_image_block_invoke dlopen libquic failed
2021-04-08 16:57:27.765417+0200 MyApp[9426:283393] [connection] nw_socket_handle_socket_event [C1.1:2] Socket SO_ERROR [61: Connection refused]
ups something went wrong: failure(-9816: Optional(server closed session with no notification))

我已经尝试更改数据库配置文件中的许多设置，但仍然得到相同的结果，我不知道问题出在哪里

提前谢谢
