What I want? I expect to use xcrun devicectl device process launch --device <uuid> <bundle-identifier> --payload-url <URL> to launch my app and pass the specified URL as I usually do in iPhone. What I do? Let's say the app A which I'm developing. I try to use UIApplication.open(:options:completionHandler:) in another app to open the app A with registered schema. And whether app A is cold launch or background resumption, app A can go foreground with receiving URL. If I use xcrun devicectl as above described, app A can still be opened. However, app A can't receive URL which I pass through --payload-url option. That's different from in iOS. BTW: I as well try YouTube with UIApplication.open and xcrun devicectl, the former way work, the latter way not work.

I have an Apple TV 4k, and I want to pair Xcode with TV in order to install my developing app. According to this answer, I can pair them on my home network. However, I can't pair them on my company's network. I suppose that the pairing procedure is through MDNS protocol. But our company's network use whitelist strategy for MDNS service IDs. So I don't know what service ID(s) is used for pairing. Can you tell me how to setup network to make pairing work?
