xcode 6.1.1 unable to boot the ios simulator

3
votes

I updated Xcore from v5.1 to v6.1.1 on OSX 10.9.5, and now the iOS Simulator will not start. It reports an error 'Unable to boot the device'.

I found other posts, such as IOS 8 Simulator unable to boot and Unable to boot the iOS Simulator - xcode 6.0.1, but the solutions in those posts do not work.

I've tried:

  1. reinstall xcode 6.1.1
  2. change xcode from 6.1 to 5.1 and back
  3. add/remove simulator device
  4. set correct command line tools
  5. reset simulator connect and setting
  6. delete the DerivedData

All above solutions did not solve the problem. There are some crash logs when starting the ios simulator.

Here are related logging:

You stated that there are crash logs, but you have not provided them. Please provide the launchd_sim crash log. – Jeremy Huddleston Sequoia
@Jeremy , i have upload the correct log – catals.liu

The most frequent cause of this problem is when DYLD_INSERT_LIBRARIES is set to an OS X library.

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.

However, now that you have provided the crash log, I can tell you that the issue is likely an issue on your system. launchd_sim is aborting because it can't create the a directory in /private/tmp. I suspect you have modified the permissions of /private/tmp such that something like this fails:

mkdir /private/tmp/com.apple.CoreSimulator.SimDevice.FE1168B2-EE8D-4C69-8AE7-99F5A80F808B.launchd_sim

You should fix permissions on /private/tmp and prevent them from getting messed up in the future. Plenty of other things will break other than the iOS Simulator as a result of this.

iOS 8.3, XCode 6.3 I had observed a similar call stack at: ~/Library/Logs/DiagnosticReports/launchd_sim_<datestamp>_<yourHostName>.crash

I'm going to emphasize what Jeremy Huddleston Sequoia stated that the permissions are to blame in some cases. (as in mine)

Fix:
sudo diskutil repairPermissions / - repairs permissions of system directories (like if /tmp is incorrect).

This worked for me in the case that I didn't have the DYLD_INSERT_LIBRARIES variable set. (i.e. "echo $DYLD_INSERT_LIBRARIES" returned blank). I was really banging my head on this one. I had uninstalled Xcode/rebooted/deleted Simulators/etc as described in multiple different S.O. posts.

Root Cause:
The problem stemmed from another application which was complaining about not having write access to the /tmp folder so I changed the permissions not knowing the full consequence of my actions. Running the diskutil command above fixed that and some more folders that it found were not set as they should be. Now my simulator runs and I can continue my UI debugging in Xcode.

Great answer Jeremy! Thank you!!

I did a sudo chown $user:wheel /private/tmp instead and it seem to have solved it for me.
