flutter run doesn't attach to observatory service on ios13 #40448
Description
This is sort of related to #37699. On an iPhone Xr device with ios 13, I am seeing very little device logs, and nothing from a flutter debug app. At first I thought this was a problem with idevicesyslog, but then I'm seeing the same thing from the macOS console app.
So I tried debugging flutter apps, running flutter apps, running non-flutter apps, changing system settings, and none of these produced any logs I could see in macOS's console app. The only logs I could get from the device where when I first attached it to my mac host: https://gist.github.com/christopherfujino/6e22a26d15c91fadd9feaf8fde97c5b4.
In an earlier version of ios, these syslogs are very busy.
My WIP PR to get flutter run to work using MDNS is #40447.
