Lots of difficulties with Xcode 15.2 trying to connect to iPhone

Xcode Version 15.2 in general is very, very slow when debugging. If I get to that, often, xcode just shows a message "Preparing iPhone 15 Pro Joride. Xcode will continue when the operation completes" This box will stay there for at least 3 min. Then it is follow by a message about a developer image not being able to get mounted: "Previous preparation error: The developer disk image could not be mounted on this device.. Error mounting image: 0xe8000115 (kAMDMobileImageMounterDevicePropertyQueryFailure: Failed to query device property.)"

If I eventually do manage to debug my app, it is soooooo slow. The launchscreen is there for easily 20 seconds (I'm guessing debugger is trying to attach during this time). When there are breakpoints present at all, things just occur very very slowly, expecially when trying to PO variables. The app itself runs fine though.

I've noticed there is a checkbox for this device that says 'Connect via network'. This clearly seems to be broken for my combination of factors, so I wanted to uncheck it. Not possible!

For those of use with a similar experience, any suggestions? (I did try to power cycle both computer and iPhone, but that did not change much. Both devices are connected to the same home wifi which has no special setup or restrictions)

I've now been unable to load any app on my device. Here is the exact error I get:

I've noticed there is a checkbox for this device that says 'Connect via network'. This clearly seems to be broken for my combination of factors, so I wanted to uncheck it.

There is a bunch of backstory, and some potentially useful tips, about this in the Xcode 15, how to uncheck "Connect via network" for physical device? MegaThread™.

  • Ouch! That does not bode well for getting this turned around to a quick and productive Xcode.
