I am using UDP communication in a app. Here is what i do,

  • Initialises a UDP broadcast connection object.
  • Bind it with a port to listen
  • Receives the IP & Port from the UDP connection to connect further with TCP connection.

After updating Xcode 15.3, It works until the iPad is connected with mac in debug mode. When i create build to test remotely, it stops receiving IP & Port from UDP connection.

Here is how i concluded this is Xcode issue, I tried to debug this issue with Xcode 15.2 and it works as expected with debug and after creating build also.

Any help / suggestion would be appreciated.

It sounds like you’re implementing service discovery. I strongly recommend that you use Bonjour [1] for that. It’ll get you out of the business of dealing with broadcasts, which are very tricky to get right.

Is there something preventing you from using Bonjour here?
