iOS Simulator cannot start

Question

I have upgraded my Mac to OS X El Capitan (version 10.11.4) and updated Xcode (version 7.3 (7D175)). I'm working on Xamarin (version 5.10.3 (build 27)). I get all iOS Simulator components (from Xcode Preferences/Components), versions 8.1, 8.2, 8.3, 8.4, 9.0, 9.1 and 9.2, no version 9.3 available..

After all upgrades and a restart I open my project in Xamarin and launch it and an error message raise to say that the iOS Simulator cannot start. I tried to create a new project on Xcode (to see if it was related to Xamarin), tried to launch it and the same issue occurs.

This is the crash report:

I don't understand why the /usr/local/lib/libwep library is not loading. There is no explicit message or information to understand the issue and try to fix it. I do not find a lot help on similar issues.

I tried this solution, but it just removed the iOS Simulator components that I just download with Xcode.

I need help, if you have any ideas, as I can't debug anymore until this simulator will start.

I always have enable application from all sources. Did I miss any other info from this question thread ? — MrGrabazu, Mar 31 '16 at 12:46
It almost looks as if Xcode 7.3 was not installed correctly and/or was corrupted, based on the fact that the 9.3 sims are not even appearing. Are you able to completely wipe Xcode (move it to trash) and install again? — cobey, Mar 31 '16 at 17:19

The issue is caused by your use of WebSense. This software injects a library (usr/local/lib/libwep) into every process, and that practice is not valid for processes utilizing library validation for increased security. Simulator.app is one such process that is making use of library validation.

You need to reach out to WebSense for a compatible update to their software.

I'm using WebSense indeed ! You are such a medium ! Thank you for this clue ! I will check with our network service to get a solution to this issue. – MrGrabazu Apr 01 '16 at 07:38
It working well before I update to El Capitan.. I think WebSense need to be up to date with El Capitan. Thank you for your answer ! – MrGrabazu Apr 01 '16 at 08:10

No, it isn't due to the update to El Capitan. The same issue exists on Yosemite. The thing that changed is that we started making use of Library Validation in Xcode 7. – Jeremy Huddleston Sequoia Apr 01 '16 at 16:04
It seems to be that, my company uninstall WebSense from my mac because they cannot succeed to find a working solution/workaround. Thank you again for your answer, it save me ! – MrGrabazu Apr 06 '16 at 09:17

What fixed for me is

sudo chmod +x /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app

I was getting this too when trying to open the simulator via Spotlight Search (⌘ + ⎵)

Despite seeing it open

My solution in the end was Force Quit then yarn ios to get back up and running.
