Hi, i got a weird issue. my app forces cellular connection using network. everything is ok but I lost the debug connection when I try to change the mobile network.

Step to reproduce:

I tried to force tcp connection to cellular network via Network using this :

let params = NWParameters(tls: options) params.requiredInterfaceType = .cellular
Tap to change status mobile network icon (on -> off or off -> on) on iOS
Debug app killed on my phone
I got popup message in Xcode : "Lost connection to the debugger on “iPhone”. "

Even my IPhone device icon still in the Xcode build bar.

iOS: 14.6

Do you have any idea?

It sounds like your app crashed in a way that broke the debugger. That’s kinda weird.

Does this reproduce if you run the app from the Home screen? If so, does that generate a crash report?
