Xcode 4.5.2在Mac OS X Mountain Lion上不断崩溃？

Question

I have been using Xcode with mac os x lion and I kept getting an error when trying to test my app on my ios device. I formatted my computer and upgraded to mountain lion and revoked all the apple developer certificates and provisions and started from scratch.

Now I do not get an error anymore but when I click run Xcode crashes. I have seen other people having the same issue. I tried installing the tools in Xcode and reinstalling Xcode but nothing seems to work. I even tried other apps. Xcode even crashes when I look at the preferences or just randomly but it is unusable. I have tried what people have suggested but I think maybe its the update to Mountain Lion.

Anybody have any thoughts on what I can do to fix it ? Thanks guys and Ill post the Xcode error below.

Answer 1

I had a problem where multiple instances of XCode were running in the background, causing XCode crashes. I'm not sure if this will help or not, but you can try the following in a terminal.

alias findp="ps -axww | grep $*"

this is just some shorthand.

see what this does.

findp Xcode

If you have a huge list of instances returning for that call, when you are not actually running Xcode, then it means you have a heap of orphaned background xcode processes. The simulator will also hold onto xcode instances, so you'll need to close that as well.

Anyway, if you have the problem i had, you'll see repsones along the lines of

 7645 ??         0:00.12 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk/System/Library/Frameworks/Accounts.framework/accountsd

you can then kill these with

kill -9 7645

Not sure if that will help you or not, but it has saved me many times when xcode has played silly buggers with me.

Answer 2

Okay, so I know it isn't the ideal solution, but what I found to work for me was to download the iOS 5.0 and 5.1 SDKs to run testing through the simulator (yes, I know this creates an issue with not being able to run tests through the current simulator...) but I can run my app just fine on my provisioned iPhone device for testing in iOS 6.0

It seems that the 6.0 simulator is the culprit in causing this particular crash. Also, if you have the same setup as I do, then you will need to be aware that you will need to stop the application before attempting to run it again, or it will result in a crash. Also, if you are running a simulator (5.1 or 5.0) then you will need to be sure that you not only stop your application, but close the simulator completely down. Otherwise, this may result in another crash.

All of the failures that I have encountered through my current environment's installation of XCode 4.5.2 have resulted in the exact same error message you received above.

Hope this helps!
