I had the same problem and it drove me nuts. I finally figured it out.

Make sure that "/Library/Application Support/iPhone Simulator" is owned by your user id and that it is also writable by you. All the subfolders should also be owned and be writable by you.

Once I changed ownership of "/Library/Application Support/iPhone Simulator" to me everything worked.

I've had a similar problem. The simulator launches but stays on a blank screen. Then when I press "stop" in Xcode it doesn't stop. I have to force quit Xcode. I've tried many solutions including reinstalling Xcode.

Ultimately, the only thing that worked was changing the debugger from LLDB to GDB in the scheme. I don't know why this works.
