Unable to boot iOS simulator in Xcode 7.3

Question

I have tried all the solutions which found on stack overflow, but still not able to resolve it. Somehow its not open the simulator and gives me error unable to boot simulator.

I have reinstall 2 times Xcode and reset simulator content and Settings Several times. But i'm not able to get any solution.

This happened to me on Xcode 8 from 18 Oct 2016 onwards. Until then everything was fine. Also get the Coretelephony trace file error on mac os startup. — Rohan Bhale, Oct 19 '16 at 06:16
I was facing the same issue with Xcode 8. Still not fixed :( — Arun, Oct 19 '16 at 06:16
I had the same issue then I keep on closing and opening the simulator for three to four times and its working fine now. — Maniganda saravanan, Oct 19 '16 at 06:18
@RohanBhale I updated my Xcode with 8 , but i faced UI issues and not able to get any solution so i uninstall Xcode 8 and reinstall 7.3. — Merry, Oct 19 '16 at 06:19
@Merry Please check this link for UI issues. http://stackoverflow.com/questions/39497572/layout-issues-after-updating-to-xcode-8/39954298#39954298. Don't downgrade to 7.3 — Maniganda saravanan, Oct 19 '16 at 06:28
@Manigandasaravanan I know this solution but i'm not using auto layout in my project . And also it's a temporary solution for Xcode 8.0. — Merry, Oct 19 '16 at 06:34
does you project build without error? or did you get any error message in the console? — Enix, Oct 19 '16 at 06:57
What is the exact error message indicated in ~/Library/Logs/CoreSimulator/CoreSimulator.log at the time of the failure? — Jeremy Huddleston Sequoia, Oct 20 '16 at 00:55
Also based on an answer in a related question (which I find suspicious), what is the output of `stat /private/tmp` — Jeremy Huddleston Sequoia, Oct 20 '16 at 00:57

I also got the same issue many times and the only solution for now is to reinstall Mac OS and then install xcode 7.3 stable version . this will definitely solve your problems.
