        A second error reads: Failed to launch IBCocoaTouchImageCatalogTool via CoreSimulator spawn. I assume that's a direct result of the above error.

         

        I'm running Xcode 11, beta 3 on Mojave 10.14.5.

         

        I have tried: Cleaning the project, deleting the product, rebooting my machine, copying the project, and re-installing Xcode. No dice.

         

        It compiles and runs without error on Xcode 10, but that doesn't help me because I'm trying to debug an iOS 13 crash.

         

        Anything else I should try?

         

        UPDATE: I was finally able to resolve this by re-downloading the Xcode beta (again!) and running it from outside the Applications folder.
