Failed to launch IBCocoaTouchImageCatalogTool via

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 7.1 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?

Answer 1

Maybe you have just cleaned Logs directory...Then you can try this:

sudo chmod 777 /Users/[YourUserName]/Library/Logs 

Answer 2

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.

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

The above answers are correct. I have a bit similar approach.

After, I use these steps:

1. Clean the project.

2. 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.

3. Run the project, this time project run without your assets and may be chances of crash. This ensures that project will run.

4. 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.

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
