When I build and run any project on Xcode, I face this error:
On the other hand, when I using command-line and install and launch the app by commands, I can see logs and everything is ok.
I did see other similar questions and I did try solutions like the clean project, build and reset and restart simulator and reinstall various versions of Xcode, but didn't fix.
My OS:
Mac Os Catalina 10.15.4
I removed some additional kexts from EFI partition, this problem solved!.

I installed Yosemite a couple of days ago. It really broke quite a lot of things - broke my favorite game which won't start, broke my php installation, my wordpress installation, and now Homebrew! But the spotlight feature is nice, not that it makes up for it lol.
Nonetheless I'm trying to fix Homebrew which is telling me to update to XCode 6.1. I've run software update and it says the XCode 6.1 has been installed (sort of). It has:
Command Line Tools (OSX 10.10) - Version 6.1 Installed Oct 17, 2014 (twice actually)
Xcode Version 6.0.1 - Installed Oct 17, 2014
And no pending updates.
But when I check the locations tab in Xcode preferences - it says it's using Command Line Tools 6.0.1. And when I run brew doctor it tells me to upgrade to 6.1 CLT.
How do I update the CLT to 6.1? (note I'm not on Apple Developer program)
The link that #richard-g provided doesn't seem to work anymore, but I just found the dmg file on
https://developer.apple.com/downloads/
using an appleID that has only a free developer login.
On that page I found both Xcode 6.1 and the command line tools for OS X 10.10 for Xcode 6.1.
Before finding that, on the first machine that I upgraded from Maverick to Yosemite that already had Xcode installed on it, I was able to upgrade Xcode in the App Store and then run Xcode and from within it download and upgrade the command line tools, but App Store continues to show Xcode as one update available with just an "Open" button. I'll see if installing the downloaded dmg takes care of that, and in any case I have other machines to upgrade and could use the offline install package. The download site seems very very slow, though, the 2.5GB download is taking all day.
It worked - installing the 6.1 XCode from this download https://developer.apple.com/downloads/download.action?path=Developer_Tools/xcode_6.1/xcode_6.1.dmg
and it worked fine. I just had to go to Xcode -> Locations and select the 6.1 CLT, then open a new command prompt.
brew doctor
Your system is ready to brew.
========================================================
Sorry as per comments - the link to XCode is no longer working
As you have Xcode 6.1 installed, you can run xcode-select --install from a shell to download the correct CLT.
This link works without without requiring login:
https://developer.apple.com/downloads/index.action
The application "Xcode5.1.1" can't be opened.
I use x-code 5.1 to build iOS apps, now when i installed x-code6 beta version to implement app with swift language then xcode 5.1 is not working. It is giving me such error-
I use to resolve problem with Xcode 4.6.3 crashing after installing xcode 6 beta but not found this useful for my case.
I have tried to restart machine but it is giving same error. I googled for it but not got useful stuff. Any help would be appreciated.
Try to select different "Command line tools" in the bottom of Xcode -> Preferences -> Locations.
You can do it in your working Xcode 6.
After trying more I found it useful
Restart your machine then it can work, if not like my case then try below command in your Terminal
sudo mv /System/Library/PrivateFrameworks/MobileDevice.framework{,-saved}
then again restart your machine then it will ask for installing few components of Xcode so allow it, then your Xcode 5.1.1 will work fine.
At first I was installed XCode 4.3. Then, I needed to install an older version of XCode, such as 4.1, to be able to test applications on the simulator iOS 4.1. The operating system MacOSX Lion.
At first I just tried to install XCode 4.1 in the folder Developer, like I did before. But as was to begin the installation I got an error message.
Then, I tried to uninstall XCode 4.3 Application of the folder by moving it to the Trash, and clearing. After rebooting, I tried again to install XCode 4.1 and got this problem again.
I tested it on another computer, which also was installed XCode 4.3, and encountered the same problem.
Maybe you know where to XCode 4.3 leaves their roots? I also cleaned the temp files using CleanMyMac.
Thank you.
I still have Snow Leopard. I have Xcode 4.2 for iOS development. This morning I upgraded my iPhone and iPad to iOS 5.1.
But Xcode 4.2 is not detecting my device for testing. I could not find the iOS 5.1 SDK image on Apple's developer site, for Xcode 4.2.
I don't want to do upgrade to Lion to get XCode 4.3 at this time.
Will I able to use Xcode 4.2 (on Snow Leopard) for iOS development now?
To get Xcode 4.2 on Snow Leopard to run code on a device running iOS 5.1 you can do this:
If you have another Mac running Lion and Xcode 4.3.1 you can copy the files from:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.1 (9B176)
Place the copied files in the equivalent place on your Snow Leopard Mac: probably
/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Similarly copy the iOS 5.1 SDK files found in this directory:
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
Also copy 'version.plist' from the Lion machine in the iPhoneOS.platform folder to the Snow Leopard machine.
Re-start Xcode on the Snow Leopard machine and re-connect the devices and it seems happy enough.
If you don't have access to a machine with Lion and Xcode 4.3.1:
You can get the files out of the 4.3.1 DMG which can be downloaded from Apple here: Downloads for Apple Developers.
Mount the DMG, Show Package Contents on the Xcode icon and drill down to
/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Follow the steps above.
You might find it more convenient to use Apple's proprietary ditto method (sudo ditto src dest) in the terminal window to copy the folders.
Note,this hack will also work for latest iOS 6 SDK.
You have to get Lion, iOS 5.1 SDK is only for Xcode 4.3.1 which is only available for Lion.
... and your Xcode will not be able to build to your device if you have already updated it to 5.1 because it won't be on that version of Xcode's approved SDKs
I'm working on this now. I have the same issue.
The MAJOR PROBLEMS here are that:
1) Apple never provided a warning dialog that this might disable people developing under Snow Leopard.
2) There is no easy way to undo this.
3) This should not happen on a point release update.
I've tried to install the previous ipsw from 5.0.1 for my Gen 4 IPod Touch from here:
where to download ipod touch firmware restore links
It will not install.
I've downloaded the Lion Xcode 4.3.1 from here (sign in as a developer first)
Lion Xcode 4.3.1
And run some scripts from the Dev Forums here:
sudo cp -R /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
sudo cp -R /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/
sudo cp -R /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.1\ \(9B176\) /Developer/Platforms/iPhoneOS.platform/DeviceSupport/
cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport/
sudo rm -f ./Latest
sudo ln -s ./5.1\ \(9B176\) ./Latest
Unmounted the Lion DMG and restarted Xcode. This allowed me to test 5.1 in the simulator but broke every build to every device with a SIGABRT or link error.
I'm off to the Apple store to have them restore my device. If I get any more information, I'll let you all know. This has been a VERY EXPENSIVE and VERY UNPLEASANT surprise.
Adding to Richards solution above, I found that if you also copy, from XCode 4.3.1 dmg...
edit: updated to correct path within dmg
/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
~~ (entire directory tree)
to
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
XCode debugger will startup correctly (without all the error log and dumps)

There is an answer here that also provides the copy of the simulator v 5.1.
No manual operations. Just open the Terminal, copy and paste the provided commands.
http://www.iphonedevsdk.com/forum/iphone-sdk-development/100229-snow-leopard-sdk-5-1-a.html
if you want to also add iphone simulator 5.1 to your xcode then copy
/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk
entire directory to the following path =>
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/
after you can also able to use iPhone simulator 5.1 to debug your application.
You can use apps compiled for 5.0 on your 5.1 or 5.1.1 device by compiling them and manually dragging .app file to iTunes. Tried today on 10.6.8 and XCode 4.2.
Download the iOS 5.0.1 firmware of your device on this link : http://www.iphonefirmware.com/firmwares-download.
And do a manual restore on iTunes.
I did it today (March 8) on my iPad 2 and it works, Apple still seems to sign this iOS version.I guess not for a long time, so do it quickly.
It is not possible to use a 5.1 device on xcode 4.2, since you don't want to upgrade, you can use the organizer, select your device, and use the restore feature. You can google for the 5.0.1 version and use that one.
(although upgrading to lion is super cheap)
EDIT: Seems this is possible, scroll up for the highest voted answer.
I am using Mac OS X 10.6.8 and Xcode 4.2 and also upgraded my iPhone to iOS 5.1. I needed to get a test version onto the device in a hurry yesterday but did't have the time to install Lion and Xcode 4.3.
I've been using TestFlight (www.testflightapp.com) for beta testing. I created an .ipa archive from Xcode 4.2 and was able to install it on my iOS 5.1 upgraded iPhone via TestFlight.
I know it's not an ideal solution but it helped me get out of a tight spot yesterday without resorting to hacks.
p.s. I'm not affiliated with TestFlight in any way.
Xcode 4.2 seems no more available on developer.apple.com for snow leopard users :( also for registered paying iOS developer like me...
It seems that at the moment there is no legal way to get it...
You must add the Symbols alias too..for example in /Developer/Platforms/iPhoneOS.platform/DeviceSupport/6.0 (10A403) you must add Symbols alias that point to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk so xcode 4.2 can detect your ios6 device (tested on mac mini 1.5 intel core solo with snow leopard). Cheers
I think you can test ios 5.1 device in Snow Leopard as explained in above posts. But it is always safe to upgrade to Lion and use the official sdk release. Because we cant predict what issue could happen if we do some "Tricks" on our machine to make it happen and it may happen when in your most unwanted time (like when submitting to appstore). :)
As of the date of this writing 3/20,2012, Apple is not letting people install previous ipsw files from 5.0.1. If you upgraded your device to iOS 5.1, like I did with my gen 4 Touch, then you either have to get iOS 5.1 running in Xcode 4.2, or you have to revert your device to 4.x, or you replace your device.
I brought my touch to the Apple Store and they replaced it.
If you install the ipsw for 5.0.1, Apple's servers will state that this is not allowed for your device and you will be unable to revert. You'll have to try 4.x to your device or make sure that the iOS 5.1 SDK is running in Xcode 4.2.
I have found how to solve it!
My system is Snow Leopard 10.6.8, and I have two sets of Xcode of 3.2.5 and 4.2, after I had upgraded my iPad 1 to iOS 5.1, I launched Xcode 3.2.5, it prompted me a window of 'unknown device was found', I answer 'Yes' to download lots of libraries from my iPad, several minutes later, I can debug and run my projects on my iPad!
Then I launched Xcode 4.2 and opened one of my previous projects, I can really debug and run it on my iPad!
In this way you can use either version of Xcode to develop apps on a Snow Leopard system.
