Failed to launch IBCocoaTouchImageCatalogTool via CoreSimulator spawn

Question

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.

Answer 1

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.

Answer 2

I had the same issue. My solution was to do the following

1. Clean the Project
2. Quit Xcode
3. Reopen Xcode
4. Build

That got it working for some reason...

Answer 3

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!

Answer 4

Had to add a step Airman00's answer.

1. List item
2. Clean the Project
3. Quit Xcode
4. Delete derived data
5. Reopen Xcode Build

That got it working for some reason...

Answer 5

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

Answer 6

If you have this type of error in your project then follow these steps:

1. Clean the project
2. And go to storyboard and select any viewController
3. And Run the project again

This will successfully resolve the error.
