未调用 Swift 本地网络 netServiceDidPublish

Question

第一个问题：我正在使用这个this method 来触发LocalNetwork Permission 对话框，但是在对话框出现并且用户授予访问权限之后，没有委托触发，但是它进入了就绪状态。 你知道为什么吗？

第二个问题：是否有可能检测是否在不触发对话框的情况下授予 LocalNetwork 权限？

import Foundation
import Network

public class LocalNetworkAuthorization: NSObject {
    private var browser: NWBrowser?
    private var netService: NetService?
    private var completion: ((Bool) -> Void)?
    
    func requestAuthorization(completion: @escaping (Bool) -> Void) {
        self.completion = completion
        
            // Create parameters, and allow browsing over peer-to-peer link.
        let parameters = NWParameters()
        parameters.includePeerToPeer = true
        
            // Browse for a custom service type.
        let browser = NWBrowser(for: .bonjour(type: "_wobie._tcp", domain: nil), using: parameters)
        self.browser = browser
        browser.stateUpdateHandler = { newState in
            switch newState {
            case .failed(let error):
                print("::: ->> error: \(error.localizedDescription)")
            case .ready:
                print("::: ->> ready")
            case .cancelled:
                print("::: ->> canceled")
                break
            case let .waiting(error):
                print("::: ->> Local network permission has been denied: \(error)")
                self.reset()
                self.completion?(false)
            default:
                break
            }
        }
        
        self.netService = NetService(domain: "local.", type:"_lnp._tcp.", name: "LocalNetworkPrivacy", port: 1100)
        self.netService?.delegate = self
        
        self.browser?.start(queue: .main)
        self.netService?.publish()
    }
    
    
    private func reset() {
        self.browser?.cancel()
        self.browser = nil
        self.netService?.stop()
        self.netService = nil
    }
}

extension LocalNetworkAuthorization : NetServiceDelegate {
    public func netServiceDidPublish(_ sender: NetService) {
        self.reset()
        print("::: Local network permission has been granted")
        completion?(true)
    }
    
    public func netService(_ sender: NetService, didNotResolve errorDict: [String : NSNumber]) {
        print("::: error: \(errorDict)")
    }
    
    public func netService(_ sender: NetService, didAcceptConnectionWith inputStream: InputStream, outputStream: OutputStream) {
        print("")
    }
    
    public func netServiceWillResolve(_ sender: NetService) {
        print("")
    }
}

问题是我没有添加“_lnp._tcp”。到卓悦服务。
