is watch os 6 support bonjour?
I can make it work on watch simulator
but when run on my watch 5 (with watch os 6.2.8)
it reports the errors:

Code Block dnssd_clientstub ConnectToServer: connect() failed path:/var/run/mDNSResponder Socket:3 Err:-1 Errno:1 Operation not permitted

any plan to support this on watch os?

Bonjour is a form of low-level networking. This is supported on watchOS, but only in specific circumstances. See Low-Level Networking on watchOS.

If your app has access to low-level networking, existing Bonjour APIs should work just fine.

I have tried start bonjour when playing audio streaming. still got the same error.
What I have done as following, anything I misunderstood and wrong?

use following to play a onlien mp3

Code Block 	let demo_mp3_url = URL(string: "https://file-examples-com.github.io/uploads/2017/11/file_example_MP3_5MG.mp3")
     let asset = AVURLAsset(url: demo_mp3_url, options: nil)
    let item  = AVPlayerItem(asset: asset, automaticallyLoadedAssetKeys: nil)
    self.player = AVPlayer(playerItem: item)

2. after the music is sound, start bonjour search. still got the same error

following is the log I printed.

Did you follow the advice from WWDC 2019 Session 716 Streaming Audio on watchOS 6?
