[Bug] Atlantis on iOS 16 could not connect to Proxyman macOS app due to "Connection reset by peer"

[NghiaTranUIT]

Description

If we use Atlantis on an iOS 16 Physical device, most of the time the Atlantis service cannot successfully connect to Proxyman macOS app.

Always get the following error:

[Atlantis] ❌ Connection to Proxyman app is failed, error=POSIXErrorCode(rawValue: 54): Connection reset by peer

Reason: We suspect that NSNetServiceBrowser is deprecated, so it might not work on iOS 16. NSNetServiceBrowser is a legacy framework for Bonjour Connection.

To workaround, use the iOS 16 Simulator.

Steps to Reproduce

1. Use iOS 16 physical device and integrate Atlantis framework
2. Start the app

Current Behavior

3. Observe that the connection is failed ❌

Expected Behavior

• The connection should work

Environment

• App version: Proxyman 3.13.0 + Atlantis 1.19.0
• macOS version: macOS Monterey

Still this bug exist in iOS 17(simulator and real device).

Version of Atlantis: 1.23.0
Version of Proxyman: 4.15.0

Step to reproduce:
Run app with atlantis on simulator (iOS 17) and stop from Xcode, then run another app instance on another simulator (diferent device type but the same iOS) and also stop, then come back to previous (from the beginning) run app instance.

I am not able to connect to Proxyman. I am getting error:

@smaky I'm working on this issue: May I ask:

Run app with atlantis on simulator (iOS 17) and stop from Xcode, then run another app instance on another simulator (diferent device type but the same iOS) and also stop, then come back to previous (from the beginning) run app instance.

Does it happen if we only open 1 app 🤔 ?

For example:

1. Launch your app with iOS Simulator
2. Verify if Atlantis can discover and connect to Proxyman.

I've tested and it works fine on iOS 17.2.
