I can't run any Xcode Swift Playground project without getting the error:
Failed to launch process. Failed to attach to stub for playground execution: error: attach failed ((os/kern) invalid argument)
Does anyone know how to solve this?
I've the same issue. If I launch Xcode using rosetta, it doesn't show anything. You must switch off rosetta and it works perfect.
To expand on #E.P's answer
To put off rosetta Go to Aplications-->Xcode-->Get info --> Uncheck rosetta.
You need to restart the system in some cases
It seems that somehow i am screwing the SwiftUI Preview. When loading the simplest Preview like
struct MaterialView_Previews: PreviewProvider {
static var previews: some View {
Text("Hello, World!")
}
}
it crashes with following error:
RemoteHumanReadableError: The operation couldn’t be completed. Transaction failed. Process failed to launch successfully. (process launch failed)
BSTransactionError (1):
==transaction: <FBApplicationProcessLaunchTransaction: 0x6000012e01c0>
==error-description: Process failed to launch successfully.
==error-reason: process launch failed
==NSLocalizedFailureReason: Transaction failed. Process failed to launch successfully. (process launch failed)
I can't figure out what causes this issue since i can run my app in the simulator w/o any errors. I use XCode 12 Beta 4. Any ideas?
I couldn't fix the issue yesterday but on starting Xcode today it just worked again. It seems to be a bug in Xcode which will hopefully resolved when Xcode 12 is out of the Beta.
To fix the error try restarting Xcode (didn't help me yesterday, but do it anyway) and restarting your Mac.
I had a similar issue, but in my case diagnostics showed: RemoteHumanReadableError
My fix was to quit Xcode (close window and quit from the menu or use CMD+Q).
Delete contents of:
~/Library/Developer/Xcode/DerivedData/
I am getting an Error on the top of my interface builder in Xcode 10.3 and while clicking on report bug and checking the log.txt file I found out that fails to open simulator. However I am not starting any simulator.
Here is the Error found in Log.txt

If anyone still looking for an answer to this after Xcode 13 update, I have tried everything they mentioned on the internet and nothing worked except one. The only thing that worked is the complete re-installation of Xcode. Completely uninstall/delete Xcode first and restart the mac and reinstall Xcode then all should be good.
Delete Xcode from Applications Folder and Empty Trash.
Go to ~/Library/Developer and Delete CoreSimulator, Xcode, XCTestDevices Folder. Empty trash
Goto ~/Library/Caches and delete everything starting with com.apple.dt.Xcode, Empty trash
Then Restart your Mac and reinstall Xcode. I used my downloaded Xcode app, AppStore installation will also work, I guess.
Now it all working.
Before that, I have changed the storyboard file using Open as Source Code mode (coz I couldn't open it in Interface Builder - Xcode just hang)
I changed the storyboard design device to iPhone 13 instead of the older device version it had.
<device id="retina6_7" orientation="portrait" appearance="light"/>
I change the existing line with this line. It kinda solve another issue of Xcode hanging, when trying to open with Interface Builder, but it didn't solve Encountered an error communicating with IBAgent-iOS issue when trying to install the app. That issue only got solved when I completely reinstalled the Xcode.
I have managed to fix it just by changing preview device on interface builder
In my case it helped:
clean project
remove derived data
close Xcode
restart Mac
I used DevCleaner XC helper app:
https://apps.apple.com/us/app/devcleaner-for-xcode/id1388020431?mt=12
removed everything, and after that restarted mac. No XC reinstall needed.
This problem caused because, I deleted all directories under "Library/Developer/Xcode" for a purpose. But, I realised I also deleted wrong directories in same time. Then I put back directories from the Bin. It is solved for me.
If you have or have had multiple versions of Xcode open, you may need to reboot or completely re-install the CoreSimulatorService, an evil, globally installed background service that somehow remains online and available to many versions of Xcode despite it being compatible with only one version.

Other symptoms of this issue: Simulators not showing up in the Window > Devices and Simulators listing and simctl throwing errors and being unable to find base iOS SDKs similar to the following:
$ xcrun simctl list
...

In my case, I just had to set team in
Project > Targets > Signing & Capabilities > Team > Personal Team
When I want to start my app, I get this:
clang: error: invalid version number in '-mios-simulator-version-min= '
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1
What's going on? When I google this error, I'm getting ZERO. This seems to be a very strange failure.
Please apologize, that I can't give more information. It's because I'm completely clueless.
Help!
OK, I've found the solution:
.xcodeproj > General > Deployment Target ----> was empty!
This is not allowed.
Try cleaning your project and/or quitting and relaunching Xcode. I've had various odd problems with Xcode that require one or the other of those things.
In my case there is a space after 8.0 like "8.0 ". When I remove space and re-build error disappears.
I am getting the following error in all my the projects after I installed xcode 4.2 in parallel with xcode 3.2.5 I get the error when I create an adhoc bundle for the Tester.
How can I resolve this?
I have gone through following blogs but can't find any solution.

I have seen this error when I manually built and signed an iOS application bundle using a Makefile. In that case my Info.plist was missing the CFBundleResourceSpecification key (should probably have the value ResourceRules.plist). I did some more testing now and it also happens if the key CFBundleExecutable is missing.
CFBundleResourceSpecification should be added in some build phase by Xcode but maybe it's a good idea to check the resulting Info.plist in the build directory if it's really there.
Maybe this blog post could help, it's about codesign finding the wrong Info.plist file (one without CFBundleResourceSpecification)
