I'm getting this error when I run my app through iphone 6s ios version 13.1.2 but it is workin with ios version 14 and up. I tried deleting Pods, brew update, brew upgrade, brew cleanup and update my xcode to latest version but I still get this error. How to fix this error? thank you so much!
I had the same error and fixed it by going into my app in Xcode under the Project Navigator, then opening Frameworks, and deleting libSwiftWebKit.tbd. I had recently updated the deployment target to IOS 12 as well as updated the Podfile, which I think had something to do with it. I think there was a bug in an earlier version of Xcode or my Podfile settings, whereby I had to include libSwiftWebKit.tbd manually, but after recent updates, that was fixed such that it doesn't need to be included manually anymore.
I experienced the same issue and was exhausted with that because I tried different other suggestions but all were in vain. In the end, Deleting the Build folder from Xcode brought me luck.
So my suggestion will be, first of all, to try to
Delete the Build folder (Xcode > Products > Clean Build Folder) or (Shift+Command+K)
If it doesn't work then try other options.

I created a new project on Xcode beta and built it, It gives me the below build error.
Encountered an error communication with IBAgent-iOS on launchscreen.storyboard.
The same storyboard error that I am getting when I try to build any sample projects built on Xcode 10 beta.
Has anyone come across the same issue with Xcode 10 beta IDE?
I face the same issue with Xcode 10.1... issue resolved by just clean the build folder using Command+Shift+K
I hope this will work for you.
I'm on Xcode 13 and still get the issue sometimes. No help with cleaning the build folder or removing DerivedData.
However, this usually saves my life ^^
sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
I had the same problem with xcode 10 installed from the App Store and I tried removing the derived data, cleaning the build folder... nothing worked.
And then I just restarted my computer and it's working. I did not rename anything. It must be some glitch in the memory which is solved after restarting the system.
I had the same error.
I renamed Xcode from Xcode-beta to Xcode and it worked for me.
You need to remove the Targets from that xib, compile and add them back to your xib and compile. It works!
I renamed the
Xcode to Xcode10 (from finder > Applications),
and then cleaned the build folder
(Xcode > Product > Clean Build Folder).
It worked for me.
Remove the product file (.app) if old build exits
Clean the build (Command + Shift + K)
I'm using Xcode 11 but still, encounter this problem, I've tried to clean the project and rebuild it but it still won't work. The only solution I found it work is to uninstall Xcode and download the new one from App Store, this work fine with me and I can use it normally now. I hope this works for you guys too. Cheer.
If you are getting this issue, then I think it is bug of an Xcode 10. The only fix is uninstall your Xcode 10 , and reinstall it again . It will definitely work. This worked for me. Thanks.
I have an iOS app that worked great in iOS 9 but when I upgraded to iOS 10, I am getting an error with alamofire. When I build the app it says
"Module file was created using an older version of the compiler, rebuild 'Alamofire' and try again"
I have attempted to rebuild it by typing carthage update and it does rebuild the framework files but when I re-add them as embedded or linked binaries, I get the same error. How can I go about diagnosing and fixing this issue? I suspect that this isn't an iOS 10 issue in particular but more just a rebuilding that I am failing to grasp.
Change Xcode's command line tools to point to the 8 beta app:
sudo xcode-select -s /Applications/Xcode-beta.app/Contents/Developer/
See the Swift 3.0 issue on the Alamofire repo for more info.
Getting this error for pods in Xcode when trying to run app:
error: A cryptographic verification failure has occurred.
Tried reinstalling Pods/repo
Reinstalling Xcode(s)
Also doesn't run on simulators:
Also, running Sierra at the moment (yes, I know).
This is a regression in macOS Sierra that multiple developers have reported in the forums and in the lab sessions at WWDC. Xcode 7.3 is not officially supported on Sierra. If you want to use macOS Sierra, please use Xcode 8.0 beta or later.
If you must use Xcode 7.3 on Sierra, you can partially workaround this bug by using Xcode.app to install the app through Build & Run, launch the app suspended from the command line (xcrun simctl launch -w booted <app identifier>) and then attach with the debugger and resume the suspended process.
Note that this issue only impact Xcode 7.3.1 downloaded from the Mac App Store. You will not hit this issue if you use Xcode downloaded from http://developer.apple.com (ie, the "drag & drop installer"). Note that you might hit another issue with the same symptoms when using the drag & drop installer. That is discussed in DTAssetProviderService could not start DTXConnection with Simulator
I got mine working now!! Not really sure what I did, at all, but I just deleted the Xcode 8 .app entirely and then I redownloaded it, opened up my project in it, did a pod install and pod update, and it's running in the simulator just like normal! Not sure what I did at all, but redownloading is worth a try, it is in fact possible to fix.
If you have reinstalled CocoaPods so that it updated from a version that is lower than 1.0.0 to 1.0.0 or above it can't hurt to delete your DerivedData folder of the project that is having problems. I don't know why it fixes a lot of bugs when above scenario is the case, but it does! You can do this by going to: Window -> Projects
Then select your project on the left (It was my "Piece" project for me)
Then click the delete button
Hope this helps you out!
Launch "Keychain Access", go to "Preferences..." and click "Reset My Default Keychain". After that I was finally able to build my projects.
Today I have updated xcode. when i tried to run project on simulator(ios version < 9.0) I got this error.
"Unable to open liblaunch_sim.dylib. Try reinstalling Xcode or the simulator runtime.
It ran perfectly on ios9.0 simulator.
here is screen shot. please help me.
This will also occur when you don't have the simulator actually installed within XCode. I recently upgraded to XCode 7.1 and didn't install all simulators and received this same error.
Go to Preferences -> Downloads
Verify you have a checkmark next to the desired Simulator you are trying to run within XCode.
If no checkmark, then install the simulator of choice. 8.1, 8.2, 8.3, 8.4
I don't think that there is an "officially supported" way to solve this yet, but have a look at this answer (which originates from this more detailed troubleshoot) for a potential fix.
[Edit] In you case, try running those:
sudo cp "/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 8.1.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/host/liblaunch_sim.dylib"{,.bak}
sudo ln -sf "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/system/host/liblaunch_sim.dylib" "/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 8.1.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/host/liblaunch_sim.dylib"
First, find the target file:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/system/host/liblaunch_sim.dylib
You need make backup liblaunch_sim.dylib
Second, copied to destination (Remember to backup)
/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 7.1.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/host/liblaunch_sim.dylib
And If need it to: iOS 8.1.simruntime iOS 8.2.simruntime iOS 8.3.simruntime All done.
Hope it helps.
I faced similar problem this problem occurs when we have multiple versions of Xcode Installed ... So i force quit all the xcode and simulator and then open the xcode version you want to open.
I have an Xcode project which was downloaded from the internet so I don't know which Xcode version was used to write it but the language is Swift 2. I opened it in Xcode 7.1 beta 1 and I get the following compile time error.
Failed to launch IBCocoaTouchImageCatalogTool via CoreSimulator spawn
I deleted the DerviedData foler, cleaned and build the project several times. Tried converting the project to latest Swift syntax but it says there's nothing to convert.
I'm all outta ideas. Suggestions?
The same happened to me and it was solved by cleaning the project. However, if you cleaned it —as you say you did—, I would try closing and reopening Xcode. Even though it seems stupid, it works more often than not.
So After Trying a bit i removed the XCassets file form the Copy Bundle Resources, build once without it and then added it again. Solved it for me.
I had the same issue. My solution was to do the following
Clean the Project
Quit Xcode
Reopen Xcode
Build
That got it working for some reason...
The above answers are correct.
I have a bit similar approach.
After, I use these steps:
Clean the project.
Remove your Assets from your project(Remove References). Run the project without assets. Now the project will show some compile errors, these are not very tricky.
Run the project, this time project run without your assets and may be chances of crash. This ensures that project will run.
Now clean the project and add the assets, now run the project. The project runs successfully.
For me it works. I hope it will be helpful to you.
The only correct solution for me that takes only a moment to perform is to delete ~/Library/Developer/CoreSimulator and all of its contents. Immediately after this the build completes successfully.
I believe the solutions that state to reinstall Xcode, ultimately refresh the CoreSimulator folder, that's why they are successful in resolving the issue.
I started experiencing the error after having upgraded to MacOS Big Sur, while using Xcode 11.6 and Xcode 11.7.
Possible solution for those struggling with the above answers.
If you've just restored your machine from a time machine backup (migrating from old to new machine), you may want to re-install Xcode.
It doesn't appear to bring the caches or other important settings across properly from the time machine restore.
I've just taken that; what appears to be a drastic step, but it's worked!
Instructions on how to do so: Completely reinstall Xcode 9
-W
I was also facing the same issue tried cleaning and restarting XCODE didn't worked for me,
so I removed xcassets and added the image sets again one by one, and that worked for me.
Had to add a step Airman00's answer.
List item
Clean the Project
Quit Xcode
Delete derived data
Reopen Xcode Build
That got it working for some reason...
Update to XCode 7.1.1 from 7.1 solved my problem.
With XCode 7.1 I used Airman00's solution but suddenly it stop working.
Hope it helps!
If you have this type of error in your project then follow these steps:
Clean the project
And go to storyboard and select any viewController
And Run the project again
This will successfully resolve the error.
Maybe you have just cleaned Logs directory...Then you can try this:
sudo chmod 777 /Users/[YourUserName]/Library/Logs
I had to restart my machine to get this to work. Just in case, here are the exact steps I did:
Clean project
Quick Xcode
Delete Derived Data
Restart machine
Reopen
I had the same problem recently with Xcode 11.4 on Catalina 10.15.4.
Rebooting, cleaning project folders, or deleting the derived data directory did not help. What solved the problem for me was to remove and reinstall Xcode (I use the AppStore version).
It is possible, that I caused the problem myself by reinstalling macOS 10.15.4 via a Combo-Update.
I tried everything . But nothing worked . So i reinstalled Xcode . I took some time . But worked
Xcode 14 beta solution
If you are finding your production Xcode 13 builds aren't working and you have Xcode beta 14 installed you can try this:
Launch Xcode 14 beta 3
Open the Platforms preference pane
Xcode 13 should now work as expected
