I have just installed xCode 6 from the AppStore and every time I open the iOS simulator it shows me this error:
Unable to boot the iOS Simulator
What can cause this problem and how do I fix it? (I am using a mid 2011 iMac with OS X Yosemite)

You likely have DYLD_INSERT_LIBRARIES set. Open up Terminal.app and run 'echo $DYLD_INSERT_LIBRARIES'
If it is set to something, I suggest you unset it (or uninstall whatever set it) when needing to use the iOS Simulator on Mavericks. I suggest you look at /etc/launchd.conf and $HOME/.launchd.conf as the likely places it is being set from (you'll need to reboot after making changes).
OS X Yosemite has changes to work around this problem, so if you actually need the software that is setting DYLD_INSERT_LIBRARIES for other reasons, I suggest you use OS X Yosemite.

Do you have any launchd_sim crashes in ~/Library/Logs/DiagnosticReports ? Can you link one of them? – Jeremy Huddleston Sequoia Sep 25 '14 at 06:52

1sudo nano -w /etc/launchd.conf ... remove the 'setenv' line, and reboot. – Jeremy Huddleston Sequoia Sep 26 '14 at 22:19

1Delete the entire line. Not just the "setenv" part of it. Based on the fact that you have nothing else in there, you can just nuke the file with 'sudo rm /etc/launchd.conf' instead of editing. – Jeremy Huddleston Sequoia Sep 27 '14 at 06:57

1From nano, you can save with ctrl-o, but as I mentioned in my earlier comment, you're better off just deleting the file. – Jeremy Huddleston Sequoia Sep 28 '14 at 17:16

Thank you so much! After deleting the file and rebooting it works :) – Ishay Frenkel Sep 29 '14 at 19:29
