local iOS Zeroconf Device vs. iOS simulator Zeroconf Visual Studio
Hello, I am not exactly sure this is the right place to ask this since it involves Microsoft's Visual Studio, but because the problem I am having involves iOS I figured I would anyway. Info: I am trying to develop a cross-platform application using .NET Maui in Visual Studio. I am on a Windows machine pairing to a mac with Xcode installed, so I can build for iOS. My local device is an iPhone 13 running on iOS Version 17.5.1. The simulators I am using in Visual Studio are all iOS Version 17+. I am using the .NET NuGet package Zeroconf which should work for both iOS and Android (Repo:https://github.com/novotnyllc/Zeroconf). I also believe I have given the correct permissions for iOS in my Info.plist. Problem: The problem I am coming across is that when I build and run my application in one of the installed iOS Simulators and I go to scan for local devices it is able to come back with 80-100 devices that we want to find, but when I build and run it on my local device it comes back with nothing found. I had searched for similar problems that other people were having and found that iOS 17+ has some potential problems when it comes to searching for devices. Is this true? If someone can help me solve this issue between the simulator and local device I would greatly appreciate it. If there is any other information that I can give to help with solving this problem please let me know. Thanks! Discovery Code: TimeSpan scanTime = TimeSpan.FromMilliseconds(2000); int retries = 4; int retryDelayMilliseconds = 2000; Action<IZeroconfHost> callback = null; CancellationToken cancellationToken = default; System.Net.NetworkInformation.NetworkInterface[] arrayofnics = NetworkInterface.GetAllNetworkInterfaces(); int index = 0; for (int i = 0; i < arrayofnics.Length; i++) { // en0 is for iOS 0 is for android. if (arrayofnics[i].Description.Equals("en0") || arrayofnics[i].Description.Equals("0")) { index = i; break; } } System.Net.NetworkInformation.NetworkInterface wifi = arrayofnics[index]; System.Net.NetworkInformation.NetworkInterface[] netInterfacesToSendRequestOn = { wifi }; IReadOnlyList<IZeroconfHost> results = null; IReadOnlyList<string> domains; var browseDomains = await ZeroconfResolver.BrowseDomainsAsync(); domains = browseDomains.Select(g => g.Key).ToList(); results = await ZeroconfResolver.ResolveAsync("_http._tcp.local.", scanTime, retries, retryDelayMilliseconds, callback, cancellationToken, netInterfacesToSendRequestOn); Info.plist: <key>NSLocalNetworkUsageDescription</key> <string>This app requires local network access to discover devices.</string> <key>NSBonjourServices</key> <array> <string>_ipspeaker._tcp.local</string> <string>_ipspeaker._tcp.local.</string> <string>_ipspeaker._tcp.</string> <string>_http._tcp.local.</string> <string>_http._tcp.</string> </array>
