Development OS & Xcode used :
WatchOS 7 beta 7
IOS 14 beta 7
Xcode 12 beta 5
Problem faced :
We are able to run and get the desired result when running this project in iOS 13 &
watchOS 6, But while running in the beta versions I’m getting error that “Failed to attach socket protocol.”

Measures Taken:
Have seen the WWDC2020 video on changes in privacy settings
.
https://developer.apple.com/videos/play/wwdc2020/10110
/
inPlist for iOS:
Added Privacy - Local Network Usage Description
Bonjour Services - in array added the Service as camera.udp
Other doubts:
camera._udp is a public service right?. If we needed to make a private service for
our app do we need to register the service to IANA
This is a screenshot of the Transcript of the WWDC video that we are following . Can
you please explain if registering our own service is good for our app or if we should
continue using public services
If you want I can add test project that we have created which is also working fine on iOS 13 and watch OS 6 but not working on iOS 14 beta and watch 7 beta
WatchOS 7 beta 7

Xcode 12 beta 5
Problem faced :
