Swift - NetServiceBrowser無法在TestFlight中工作

我有這段代碼可以在本地網絡上找到一些服務。如果我在我的iPad中安裝應用程序或使用模擬器，它將正常工作，但如果我使用TestFlight，我找不到任何服務。感謝您的幫助Swift - NetServiceBrowser無法在TestFlight中工作

import Foundation

    let browser = NetServiceBrowser() 
    var arrayService = [NetService]()

     super.init() 
     browser.delegate = self 
     browser.searchForServices(ofType: netService, inDomain: domain) 
     //var arrayHosts = hostStuct.arrayHosts 
    } 

    func stopService(){ 
     browser.stop()

    func netServiceBrowser(_ browser: NetServiceBrowser, didFind service: NetService, moreComing: Bool) {

        ipStringBuffer.deallocate(capacity: Int(INET6_ADDRSTRLEN)) 
       }

    } 


    func netService(_ sender: NetService, didNotResolve errorDict: [String : NSNumber]) {

嘗試使用此代碼獲取地址：

for address in sender.addresses { 
    do { 
     var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST)) 
     try address.withUnsafeBytes { (pointer:UnsafePointer<sockaddr>) -> Void in 
      guard getnameinfo(pointer, socklen_t(address.count), &hostname, socklen_t(hostname.count), nil, 0, NI_NUMERICHOST) == 0 else { 
       throw NSError(domain: "domain", code: 0, userInfo: ["error":"unable to get ip address"]) 
      } 
     } 
     let ipAddress = String(cString: hostname) 
     // heres your IP! 
    } catch { 
     print(error)  
    } 
} 
return parsedAddresses
