I will do the above next time it occurs. Of course I just tried it, and all works normally. Go figure. Thanks

I despise finding the answer less than 15 minutes after I posted the question. It's so embarrassing. Anyway, I really did a lot of Googling, with plenty of wrong answers. And then buried within the useless pile I found this: In Xcode's Project Navigator Window simply right-click the file you wish to view and select Open In a New Window. Not sure which is more embarrassing, that I found the answer after posting the question, or that the solution was so obvious and I didn't try it.

It appears I asked this in the wrong forum, my apologies

I just went through this today! Go to https://developer.apple.com/news/?id=jxky8h89 and scroll to Configure exception domains Walks you step by step how to if you don't have info.plist anymore.

As I stated in the OP , this doesn’t work.

plug your phone into Finder itself I'm not sure if this means something in particular. Viewing the iPhone in Finder shows nothing of files, etc etc. Just all about syncing. If there is another mode or something would love to find out.

No message whatsoever....getting annoying as it hasn't worked properly in the past hour. Have do manually airdrop all the files from phone to Mac.

So it's definitely that Xcode wins the debugger over the phone via WiFi, and not the cable. Now if I could just figure how to turn that part off, without having to disable WiFi on my entire phone at the start of every work day.

I've been scouring the web for days. Is there any solution to this? Having to shut off WiFi every debugging session is ridiculous.

But this would require I am using something like NavigationStacks, correct? I'm not using those. One view calls another and so on.
