Which version Xcode? How many versions installed?

I'm using Xcode 6.4 (one version) with iOS 8.4 Simulator on OSX 10.10.4.

It has been working since this week...

Go to your perfreneces and navigate to locations and clear down the builds you have, then force quit simulator, then run your project.

Are you launching the sim via the file/dev tools menu or by testing a certain project?

Both (file/dev tools & certain project) are not working.

Thanks for reply. you mean cleaning the derived data folder? I already tried that...

I get the same problem , have you fixed the problem?

Please reproduce, then take a sysdiagnose (sysdiagnose -q) and file a radar with that and a tarball of ~/Library/Logs/CoreSimulator attached. Report back the radar number, and I'll take a look at it.

Same error Xcode 7.3.1 ON OSX 10.11.6

siva, please take a sysdiagnose immediately after trying to boot the simulator. It is imperative that you do it *immediatley* after in order to get a snapshot before the 30s watchdog timer fires. If you see the error dialog, you missed the window. Include the sysdiagnose and ~/Library/Logs/CoreSimulator/CoreSimulator.log in a radar at http://bugreport.apple.com

Hello Jeremy,


Can you check my sysdiagnose and Simulator logs and help me?

Thanks

I suggest you create new threads for new problems instead of replying to very old unrelated ones.


The error in your case was that your WatchKit App Extension's bundle identifier didn't match your iOS App's bundle identifier.

I got the same error and this is how I solved it. First, the workspace is newly copied from another machine. Then after reading this thread, it occurred to me the simulator may be the issue. So I checked and it only had the ones that were from my other mac. I then created a new simulator and used that one to run the application. It worked! Problem solved. I hope this helps just like reading this thread helped me.
