I'm using XCode 4.3 (on Lion) and my iPod touch 2nd generation does show up, but displays "The service is invalid" (0xE8000022). I've tried every possible combination of restarting/reconnecting the device and have even restored the OS on the device... any ideas on how to further figure this out?
EDIT - initially I suggested restarting the device but I realized you had already done this.
I think this answer might be valid:
Error : The service is invalid

I am trying to get a device preview running on my iPad Pro (4th Gen.) running iOS 14.3. My MacBook Pro is running macOS Big Sure v11.2.1 and Xcode (Version 12.4 (12D4e)).
I am using a project provided by Apple (SwiftUI Tutorial). You can download the project profiles here: https://developer.apple.com/tutorials/swiftui/building-lists-and-navigation
When I want to preview this project, the iPad runs Preview, the App opens as far as I can see but the screen remains white.
The Error I am receiving:
RemoteHumanReadableError: Failed to update preview.
Error encountered when sending 'display' message to agent.

I can't imagine that this is caused by a bug from Apple, so I wonder how I could fix this. I would appreciate any help a lot.
I have a part answer to my problem. Instead of starting the real device preview from the preview panel on the right, I chose the play button on the top left. This way, you have to restart the preview every time you made changes and want to see them on the real device but at least building and previewing is fast.
Make sure that your connected device at the top bar is selected (on the screenshot it is not, you can see that because of the blue icon)

after updating Xcode to Xcode 12 and upgrading my physical test device to iOS 14, I am having a peculiar problem with my app. I have two textfields for username and password, and if I fill out the username, and click on the textfield for password, the keyboard pops up but the apps CPU usage increases drastically to 99% and the app freezes. This has never happened before, and I haven’t made any changes that should cause this. I tested the same build on an iOS 12.4 and iOS 13.7 device, and they did not have the same issue. This seems to be happening only on iOS 14 devices. Another peculiar thing that happens is that if I fill out the password and then the username, the issue does not occur. I haven’t made any changes to textfields , the only thing that I am getting different from this build is that “archiveRootObject” has been deprecated. Could that maybe cause the issue here?
After debugging for a while I also found this weird message on Thread 1 “Application violated contract by causing UIApplicationMain() to return. This incident will be reported.” Has anybody faced this issue before?
EDIT: If I write a value in the username textfield, and then remove it, and then try to enter in password, the app works fine. Its only if the username textfield has a value before the password textfield has a value.
After many failed attempts at fixing the problem, and waiting for weeks until Apple answered my questions, the problem has finally been solved. It was actually just updating the "MaterialComponents" pod to version "119.1.0" that solved the issue. It took some time to update as we had problems with the pod but we eventually got it working. Thanks everyone for your help!
try this and restart your system
"Simulator -> Edit -> Automatically Sync Pasteboard" canel selected.
"Hardware -> Restart"
Device -> Restart
I am running Xcode 8 on macOS Sierra 10.12.2, and there seems to be a problem with running the simulator on my first "Hello World!" app (simulating iPhone 7 Plus). As you can see, I am very new at app development.
The simulator gets stuck at the loading bar with the Apple logo for about 10 to 15 minutes, and then gives me the message of "The operation couldn't be completed. (Mach error -308 - (ipc/mig) server died)".
I dug around the web and found solutions suggesting to go to Product > Clean in Xcode, also Simulator > Reset Content and Settings... in Simulator.
After which, the system gets stuck at the spinning clock for about 20 minutes and gives me the error message "Unable to contact local DTServiceHub to bless simulator connection" (solution I found online tells me to "Reset Content and Settings...")
I'm just really lost here because the error codes seems inconsistent in ways I cannot explain. Maybe it is my laptop? (Early 2011 MacBook Pro 15" 4GB ram, 2.2GHz Corei7)
Thank you in advance for your effort to help me.
On older/slower Macs the first run of an App on a simulator will be slow like this and an error often occurs:
The Apple logo bit is the simulator initialising (just like a real device when you cold start it) - just be patient and let it finish.
The error I suspect is something in XCode timing out due to be excessive delay. If this happens don't clean, just re-run: the simulator should not need to re-initialise so everything should be quicker and on my slow Mac setup the error does not tend to re-occur (unless I shut down or close the simulator - in which case I have to wait for it to re-initialise again!)
Helpfully you can manage without getting a new Mac :o)
I usually do this on Xcode 8.3.3.
Uncheck Debug->Optimize Rendering for Window Scale
Check again Debug->Optimize Rendering for Window Scale
It will work now
No Xcode simulator is not slow, It may be because slow animation is checked
Select Simulator
Debug Option and uncheck slow animation
That's work for me. Hope it works for you
When I use the iOS simulator I've no issues with attaching to a process. But when I want to attach to a process on my iPhone it doesn't work. When I type in the process name and click on Attach it takes a while before showing me the following error:
It seems that I get the same error for any process identifier, even when the process identifier doesn't exist:
I think this issue is due to my iPhone (5S iOS 8.3), because on another iPhone (5) I don't have this issue. Can someone please help me...
This issue was only occurring on my iPhone 5S and after a factory reset the issue didn't occur anymore.
When I try to do anything in Playground, this pops up before I even finish typing a word.
Error running playground.
Failed to launch iOS stub for playground: The operation couldn’t be completed. (Mach error -308 - (ipc/mig) server died).
and when I just try to run IOS Simulator I get the following error
Unable to boot the iOS Simulator.
oh and this error just popped up
An error was encountered while running (Domain = DTiPhoneSimulatorErrorDomain, Code = 2)
I tried rebooting, I closed out and opened again, I deselected file and reselected. Just keeps happening. Anyone have a solution?
Your firewall is blocking the debugger, you need to allow it to connect:
TCP out 127.0.0.1:63748
Or allow the debugserver process open access (whichever you, or your firewall, prefer(s)).
Upon enabling it, and restarting Xcode everything should work like a charm.
Note/Update:
If you're having trouble finding, or allowing, the debugserver simply try, temporarily, disabling your firewall and restart xcode. Does the playground work? Oh, and don't forget to make sure you've got the assistant view open and the output box showing.
Currently the Xcode 6 beta needs to reside in \Applications for the playground and simulator to work. After you move it there you need to reboot.
This error popped up for me when I closed the simulator before Xcode finished attaching my application to it. Opening the simulator and running the app again solved this problem.
