Did you ever find an answer to this, i'm getting the same message

I'm see these issues but also I'm see extra updates too on Xcode 13.4.1 I have created an environment object that i pass to child screens. I'm seeing the .onAppear() being called on the parent screen when a child screen updates a field in the environment object This is really starting to hold up development

32 gig of memory on an M1 Max MBP and it's awful debugging on Xcode 15, do Apple look at these forums or is it better to leave feedback at https://developer.apple.com/bug-reporting/

I think I know what problem is, for me it seems that instead of using the usb cable to debug the app on the device, XCode is using WIFI even though I'm selecting a device that is connected over USB I turned off WIFI and just used ethernet to connect to the network. So Xcode was forced stopped using WIFI to talk to the device, but instead it used the USB cable Then all the debugging went a lot faster It seems that Apple have been making changes around Window -> Devices And Simulators. On Xcode 15.0.0 the 'Show run destination' could not be set to Never, but now it works ok. I'm just guessing but it seems that Xcode is trying to connect over WIFI to all the devices and send all the debugging over WIFI even when usb is connected. Turning off WIFI on the MBP and using ethernet worked round the issue and debugging to the device went a lot faster....hope this helps!

I was hitting this problem and found Xcode kept trying to connect to other devices that it had used previously, even though I wasn't current debugging with them. eg, it would try and connect to my personal phone and watch over the wifi network even though I wasn't using them and I had the test device connected via usb. As a workaround i tried two things (not sure about the second one, but it all seems pretty good at the moment). First thing I think helps the most was go into Window | Devices And Simulators and set the Run Destination for all devices to Never and then go back to just the devices u want to debug to Auto or Always - hopefully this will stop Xcode trying to connect simultaneously to anything it has ever used. I've also got both ethernet and WIFI running (can't get air drop to work over ethernet, despite Apple saying iOS 17 it does work, and the ethernet interface is much faster generally). So I've changed the priority of the services in System | Network so that ethernet is above WIFI These two changes seem to help a lot and for me it's back to what it used to be

Yeah I'm seeing the same thing on an iPad pro on 17.2 and Xcode 15.0.1 when logging into TestFlight, no idea what's causing it, it just won't let me use TestFlight. I think this is a problem at Apples end with the account, I tried a different TestFlight account on the same device and it worked ok
