Unable to boot iOS 8 Simulator

votes

I have just updated my Xcode to 6.0.1 from Mac App Store, and my OS version is OS X 10.9.5. The problem is that the iOS 8 Simulator is not loading, but the iOS 7 simulator is working fine.

Every time I try to boot an iOS 8 simulator device, I get an error message:

"Unable to boot iOS Simulator"

Make sure you choose XCode6 as Command Line Tools in Preferences > Locations Section,look at this stackoverflow.com/questions/24033417/… – Sport
You can try: Force quit all other simulator then try to run the iOS8 simulator. – souvickcse
@ Sport. Thanks..That is selected by default. – Shakti
@ souvickcse...Yes I tried that too but no success. – Shakti
@PREMKUMAR..No. I am still fighting with it. – Shakti

The main cause of this error is that DYLD_INSERT_LIBRARIES is set. I suggest you unset DYLD_INSERT_LIBRARIES (likely in /etc/launchd.conf) or otherwise uninstall the product that set it, and then reboot.

OS X Yosemite has a software change to deal with this situation, so if you need the product that was setting DYLD_INSERT_LIBRARIES, I suggest you update to OS X Yosemite for your development.

Go into Window->Devices. Find the simulator that's not working, right click and delete it. Then click on the "+" button at the bottom and you can add it back in.

I had to delete a few of them, and this only takes a minute.
