I am using Xcode 9 beta and running on iPAD OS version 10.3.2. But while running Xcode is warning as in attached screenshot. It is loading and loading....
Same here.. Wait for 20 to 30 minutes and will work !!
restarting the iphone helped me in this case. Now building/running app is normal.
I waited 5 minutes and it worked! So, just be patient! :)
Tried hard-clean build (command+shift+K) and clean build folder (command+shift+opt+K), then detach and reattach the device worked for me. Not sure why, though.
In my case this happens after installing a new version of iOS, at least with betas from 11. I just wait a few minutes, as I did previously with the "Processing symbols" status whenever I attached the iPhone after an update.
in my case, for :
Preparing debugger support..
i just relaunched Xcode and reattached my device..then i got :
Amin is busy .......
and I restarted my IOS and it ask me for verification and done.
hope help you.
I waited for at least 1 hour but nothing happened. Then I restarted my device and again nothing changed. Finally! I restarted my machine and then it took only 5 minutes to get prepared for debugger. And then I was able to test the apps again on real device.
It can just be that iTunes in the background wants to connect to your device.
Close all open background apps. I did it worked for me
I think XCode is downloading the DeviceSupport folder for this particular iPhone/OS combination
Sometimes it got messed up. Normally it takes 2-15m. But it may stuck on without showing loader.
You can clear Trusted computers and reconnect the device.
Settings -> Developer -> Clear Trusted Computers
This process may speed this process.

I'm looking for more information on the message below. Xcode 9 seems to be hanging for a couple minutes already...
How can I tell Xcode 9 to quickly recognize my previously used device updated to iOS 11?
.Alex’s iPhone is busy: Preparing debugger support for .Alex’s iPhone
Xcode will continue when .Alex’s iPhone is finished.
There are multiple solutions for this:
Solution 1: Patiently wait for 10 to 15 minutes. Have a tea or roam around ;-)
Solution 2: Disconnect device from the system. Restart both iPhone and Xcode and then rebuild again.
Solution 3:
Go to Windows → Devices and Simulators (Shortcut key: cmd+shift+2)
You’ll see iPhone device connected to system with message
iPhone is busy: Preparing debugger support for iPhone
Click on plus button (+) present in bottom-left corner.
This will show the device connected to system. Click on Next button.
Thereafter you’ll see ‘device setup was successful’. Click on Done button.
Solution 3 worked for me!
Solution 4:
Unpair your device and then pair it again. Thereafter follow Step 3.
I clicked ‘Cancel Running’, opened the Devices list, unpaired my iPhone, removed my USB cable and reconnected it, paired the iPhone, and then was asked on my iPhone to enter my passcode ("pin code"). Did this and then was finally able to pair my phone correctly.
Wait a few minutes. The application will start automatically
Restarting Xcode worked for me (quit and start again).
What didn't work for me:
waiting for an hour on one device
waiting for an hour on another device
restarting devices
unpairing/pairing devices
It turns out XCode opens device manager window beneath it and waits for you to hit the next button. Switch to that window, hit next and you get the progress bar for the process to show up.
In my case, iTunes was open, so
1 - open iTunes
2 - access you phone
3 - click to disconnect your phone
Now the device is ready on XCode
Hope it helps....
below solution worked for me, follow steps to resolve your issue:
Step 1: Cancel Running
Step 2 : open Window menu and select Devices and Simulators
Step 3 : Unpair the iPhone
Step 4 : Removed iPhone USB cable and reconnect to the system
Step 5 : Pair the iPhone when you connect then you will be asked to Trust or Don't Allow, Please click Truct on your iPhone and enter your passcode (Pin Code)
Note : I performed all the above steps they worked for me. The issue of my device debugger gone.
Below is the Screenshot of Devices and Simulators Menu
I unplugged my cable and saw this. After it reached the end I was able to run it no problems.
You don't have to unplug to see this; just hit cancel and you will see its progress.
On your iPhone:
Settings > Developer > Clear Trusted Computers
Wait a few seconds, it's all.
Click on Window menu
Select Device and Simulators
Select your device
Click on + button at bottom left corner
Click Next
Click Done
I found deleting the app from the device and re-installing with Xcode solved this issue.
I have been using my iPhone X to debug via Network and suddenly had this problem.
Disable "Connect via network" and try again with USB.
This trick worked for me.
I realised I had less than 100 MBs of free space on my disc. Freeing up disk space solved the issue for me!
Simple solution:
Open Window -> Devices and Simulators
Unpair iPhone on the side list
Unplug and plug again the USB cable
Press Trust in the prompt message in the device!
Then it should work! It worked for me
I had the same problem many times, these things worked for me:
restarting my phone + xCode.
checking that both your Mac and your iPhone are connected to the same Network.( has a high potential ).
repairing my phone.
When you plug a New device which is having iOS 11, Xcode 9 will Prepare Debugger Support for that device, At this time you should Wait to complete it.
Then run the project in that device it will run smoothly.
If you didn't keep patience while creating Debugger Support then it will throw the error mentioned in the question.
My setup
macOS 10.14.6
iOS 13.2.3
Xcode 11.2
Tried all the "speedrun" tips up till 2019-11-24 without luck.
The wait seemed inevitable but incredibly long in my case:
with a freshly upgraded iOS version.
I then found this comment on reddit which makes the most sense:
This is required when you connect a device with an iOS version that
the respective computer's Xcode didn't see before. It saves them in
/Users/username/Library/Developer/Xcode/iOS DeviceSupport and it does
take a while. Don't restart Xcode as it will not help you, just wait
for it to finish.
It takes quite some time because these debugger
support files occupy a lot of space (29 GB for me), though you can
safely delete any version from there, and if you connect a device with
that version again, it will re-save it from scratch.
So if you just upgraded your iOS, then the "from scratch" part could take longer than usual, also depending on your network condition. In my case, it is definitely much much longer than the "10-15min" other people claimed. I measure it by hours.
A lot of tricks seem to have worked but they neglect the fact that time goes on as you try things while Xcode keeps working on the setup in the background, and quite possibly resumes its job whenever you do a restart/reboot cycle.
This led me to noticing that my Xcode version is just one step behind the iOS point release. After upgrading my Xcode, it worked.
But it took longer because I removed the iOS DeviceSupport folder by following a tip!
So here are my suggestions:
Check your Xcode version down to the minor version to make sure it should actually support the iOS version.
Check your Mac's free disk space to make room for newly generated device support content under ~/Library/Developer/Xcode/iOS DeviceSupport as this tip suggested.
Check if you have connected your device to a fast-enough USB port, as this tip suggests.
Wait till Xcode finishes "preparing for debugging".
If it doesn't finish in a few seconds or minutes, keep waiting.
DO NOT remove any folder as some tips may suggest. Removal would simply make you wait longer!
The Best way:
Disconnect the Iphone.
Clean xcode by command+ shift + k or by going to Product -> Clean
Connect again
Run again
rebooted iPhone, closed all other open applications and unlocked phone worked
Clean : Shift-Command-K is what works for me.
For me it Worked after following the below steps
Step-1 Go to Devices and Simulator
Step-2 Deselect Show as run destination and Connect via network Options
Wait for Few seconds to Load the Xcode, If you want you can restart Xcode also.
Step-3 Follow the same steps and got to Devices and Simulators
Tick back both the options and it will be normal to install your app back.
Do this Two Task to solve your problem:
First Go to Xcode then -> Preferences -> Accounts then below click the plus icon to add apple id it must me same as your iphone device apple id.
Second Just change the cable if first solution can not work
I updated to iOS 11.0.3 then the error appeared. After restarting my iPhone and XCode, it showed "Could not launch the app", so I navigated to the phone's device management to trust, then it solved.
I had this problem because I hadn't given iTunes permissions to run on the computer. (I don't use iTunes for music, so I had foolishly just hit "decline" in annoyance whenever the EULA dialog box came up.)
Unpaired my iPhone
Removed my USB cable and reconnected it (Do make sure that you unplugged the USB and plugged it back in)
Paired the iPhone.
(3 important steps)
Xcode 10.3 Solution
The following error messages apply:
iPhone is busy: Preparing debugger support for iPhone
Xcode will continue when iPhone is finished.
An error was encountered while attempting to communicate with this device. (The service is invalid.)
Please try rebooting and reconnecting the device. (0xE8000022).
Follow the steps in Jayprakash Dubey's post above
and
Close Xcode;
Delete contents of DerivedData folder ~/Library/Developer/Xcode/DerivedData
Restart Xcode & iPhone
Pair Xcode & iPhone again
& run application
Today, I have faced the issue and tried out everything mentioned here and different pages as well. Nothing worked for me.
Lastly, I have reset the iPhone, then tried building the application and finally it worked for me.
I updated my iPhone to the latest version 11.0.3, then restarted my iPhone. Restarted my XCode 9. Then it worked.
For those looking for solution with Apple TV, I just experience the exact problem "Apple TV is busy: Preparing debugger support for Apple TV” with Apple TV 4K with my Macbook Air (Early 2015)
The solution is not to unpair or restart devices. But to switch network. I brought it to a faster and more open network and it works perfectly.
TL;DR: Settings > General > Profile & Device Management > (Under DEVELOPER APP category) click my email address that happens to be my Apple ID > Trust Developer
This might not be relevant to anyone else, as I am new to iOS development and this was my first attempt to install an application on my phone, but I'll provide the answer as it wasn't yet listed.
I went through restarting my phone, restarting Xcode, unplugging and plugging back in, clean building, and even removed the device from the Devices and Simulators menu. However, I believe the cause for me was that I hadn't added my developer certificate to the listed of trusted certificates on my device.
I am on iOS 10.3.3 so the navigation and wording in Settings on the phone might be slightly different, but the final step I took before this issue was fixed was to trust my developer certificate as an individual developer on my phone.
To do that, go Settings > General > Profile & Device Management > (Under DEVELOPER APP category) click my email address that happens to be my Apple ID > Trust Developer
Whether or not that was the cause of my problem, I am unsure. This was, however, the last step that I took before the app ran on my phone successfully after doing all of the other steps listed above.
I have a UI test suite that I am trying to run on device. But XCode always reports an error
Things I have already tried:
Clean and build
Clean and clear derived data and build
Uninstall the app from device
Restart the XCode
Restart the mac
Is anyone is also having such issue? Please help.
Restarting the device helped me.
I faced the same problem.Then i followed the below steps.
1.clean xcode
2.delete derived data
3.switch off and on iphone.
4.Build & Test it.
It worked for me.
I had the same problem and I have a little faster solution:
Hold power button till shutdown bar appears, then hold main front button (approx. 10s - till shutdown bar disappears). It should clear iPhone RAM.
I just updated to Xcode 7 and ran an app on a live device. Now for some reason, I get an error when I try to run an app in a simulator.
Stop “(null)”?
An instance of “(null)” is already running. Choose “Stop” to terminate and launch a new instance.
When I press the stop button it grays out, as in the screen shot, but nothing happens. I have tried resetting the content and settings on the simulator, but that didn't help.
Getting this as well with Xcode 7.
I've been following these simple steps to avoid seeing the error:
Build your app.
Run your app.
Annoying, and not a solution, but I think this is a bug within Xcode 7.
Completely quitting Xcode 7 and reloading resolved the simulator is already running it for me.
I got this error too, and building and then running the app (cmd+b ; cmd+r) solved the problem.
TL;DR: This is a recurring error in XCode 7 with no known solution. To get rid of it, disconnect your device, then reconnect and carry about your day. If running the simulator, kill it, then restart it. Hopefully Apple addresses this soon.
When you get like this stop (CMD+.)the stop the project.
->Quit Xcode
->Clean the project (CMD+Shift+K)
->Build the project(CMD+B)
->Run the project(CMD+R)
If you are running on an actual device, I found that by disconnecting the device (iphone) from the computer/laptop and reconnecting eliminates this error/issue.
However, I still see in xcode the following message:
running <app name> on <phone name>
But at least I do not need to quit xcode.
I did not have this when running on a simulator (always testing on a real device...)
I suggest building your app and then cleaning it. For me, this ensured that later on I could just run the application.
Any ideas? It was working an hour ago, now everything is dead and the status page says all is good
try disconnecting any devices you have connected.
I just tried everything SO suggested, reboots, wifi restart, iphone hotspot, nothing helped, so I unplugged my device and suddenly xcode connected and teams were fetched.
Just to say, I've had this issue a few times in the past week.
I'm using Xcode 6.4 with OS X Yosemite (v10.10.2), and from time to time, it just hangs on the "Fetching list of teams" message.
Most of the time, it works fine, but then it'll start to time-out, or throw an error like this:
The solution: reboot my MacBook. It fixes the issue every time.
It's odd. All other applications can happily access the internet, but for just this one part of Xcode, it seems unable to fetch the data it needs, and only a reboot sorts it out. I didn't have this issue before.
And it's hard to identify if this is an issue with Xcode 6.4 or OS X Yosemite, and Xcode demanded that I upgrade to the latest OS before it'd let me update to 6.4 (so I could actually debug an issue with iOS 8.2) so both updates happened on the same 1-2 days.
Bug ? Bug ? Did I say "bug" ? Course not. It's an undocumented feature.
(Sigh.)
Five hours later
I've just had the same issue again...
However, this time, I turned off WiFi on my MacBook, then turned Wifi back on again.
And the problem went away.
It (almost instantly) managed to load the list of (two) teams that I belong to.
Hope this helps.
I know that is late for answer but maybe my solution could help others.
IT ALWAYS WORKS FOR ME:
Step 1:
Go to Xcode --> preferences --> accounts
Step 2:
Select your team name and click in view details
Step 3:
Click in
Final step:
Go to Window --> Organizer and try to upload again your app :D
i resolved this by deleting my accounts and setting them up again. none of the solutions above worked.
This worked for me by disconnecting from my WiFi then reconnecting.
Quit xcode and simulator. Open organizer and click on Upload again. This worked for me.
I tried adding the account again and also reconnected the wifi but it did not work for me but quitting xcode did.
Actually I think it is an issue at Apples server.
I just got through once 30 minutes ago but had set the wrong build version and now I get the same error again. I think we have to wait.
i had same issue when i had changed my account's password.
first time, i just authorized it through new passoword. (it's not working)
and then.
remove all appstore accounts on xcode
add same account with new password.
it work.
Just keep retrying, I suspect the issue is on apple's server side and retry attempts will eventually get through.
You should get the list back within a second or two, so you can cancel the attempt and retry quickly rather than wait for the timeout.
Restarting wifi seems to help some people but not others.
Check your internet connection.
Upgrade XCode, 7.2 fixed this for me.
I noticed that I had some connection problems.
The ethernet cable was not fully plugged in.
On wifi, make sure you have a good signal.
I had same issue, and I resolved it.
I got hint from #jab11
I have external storage for TimeMachine. Around a week ago TimeMachine start to fail backup my disk.
I plugged out external storage not properly When it happens.
So, try like below.
Plug in your external storage if you have one.
Check your partition's health. (In my case, I erased partition which is causing fail to backup)
open Xcode Organiser, then upload your binary.
I hope this help.
For me, I removed all accounts in XCode -> Preference -> Accounts and ADD account again, then it's working well.
No app can run in my simulator, although building is good.
Error messsage is below:
Unable to run app in Simulator
An error was encountered while running (Domain = NSPOSIXErrorDomain, Code = 3)
In my case, I tried to run the app on a iPhone 6 simulator when I got this error. Quitted the simulator only and re-ran the app on iPhone 5s (8.1) - it worked fine.
After a while I changed the target back to iPhone 6 (without quitting it), and ran the app against it - no error shown.
As mentioned in the Xcode 6.1 Release Notes and in my sticky post in the Apple Developer Forums for the iOS Simulator, this is a known bug in iOS.
Upon installation of an app, SpringBoard will SIGKILL that app's
process in order to force a relaunch of the app with the new
executable. The problem is that there is a race condition whereby
SpringBoard may accidentally SIGKILL a new process that we just
launched rather than the old process. Which of the various error
messages you get depends on exactly when in the launch process the
SIGKILL was delivered. Normally, this shouldn't happen, so the advise
is to just try again (sorry =/). If you find that this happes to you
all the time or more frequently than you can tollerate, we are
incredibly sorry. We are aware that systems with slower disk I/O will
see this happen more frequently than faster systems, so if you are
using an NFS home directory, you may want to create a local directory
for your simulator data and setup a simlink to it from
~/Library/Developer/CoreSimulator
By Quitting the Simulator and Run the application worked for me.
For me , just Reset Content and setting in your simulator
Restart Mac can solve the problem for me.
This error is less severe than "Domain = DTiPhoneSimulatorErrorDomain, Code = 2" error that I had when I switched to Xcode 6.
For this one, I just reset and cleared contents on my Simulator...quit. Rebuilt and ran my app...and it works.
Every time this has happened to me (as of this writing, still happening on Xcode 6.1) I do not need to restart my mac to fix it. Instead I only had to restart the simulator. I exit the simulator by right-clicking on its icon in the tray and selecting the option to Quit. The I re-run my app and the simulator starts from scratch and runs my app with no error. Much quicker than re-starting the mac.
Well, I had the same error popping up, but since I force quitted the simulator then ran the project again I got it fixed and running fine. Hope that helps you :)
If this error occurs with ionic framework, make sure you have an app id given in your config.xml
This is a generic error which says that it is unable to launch the app. The real error is in the log file. Go to the Simulator menu, Debug / Open System Log. Then press Reveal button to open the folder with actual Simulator logs. In my case it was CoreSimulator.log.
Here you will find the real error. My error was Could not register service com.apple.gputools.agent.producer.sim .
After a lot to struggle and trying all suggestions for half a day, I just went to simulator menu and chose File / GPU Selection / Use External GPU when available. That's it.
please download new xcode_6 beta 4. your project will work in simulator. As i have tested as well.
Sometimes the beta version of XCode is wrongly configured to use the command line tools from the previous xcode version.
This solution should fix the issue for you : https://stackoverflow.com/a/25415781/512504
