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?

With XCode 7.1 I used Airman00's solution but suddenly it stop working.
Hope it helps!

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.

I had to restart my machine to get this to work. Just in case, here are the exact steps I did:

Maybe you have just cleaned Logs directory...Then you can try this:
sudo chmod 777 /Users/[YourUserName]/Library/Logs
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!

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.

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.

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:

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.
