Xcode encountered an internal logic error_问答_开发者

Need help I get the following error when i try to change anything in buildsetting section in Xcode 4.Once i change the value immediately i get the error as follows and xcode crashes.

Xcode encountered an internal logic error. Choose "Continue" to continue running Xcode in an inconsistent state. Choose "Crash" to halt Xcode and file a bug with Crash Reporter. Choosing "Crash" will result in the loss of all unsaved data.**

"Xcode crashes." ...and stop.

This is clearly a bug with Xcode. You don't have the source for Xcode and neither do we, so we can't debug the problem for you. Since it's clearly a crashing bug it's nothing you're doing wrong (so we can't tell you how to do it right). This means it's not a programming question, so it's off-topic for StackOverflow.

Please file bug reports with the respective software vendors for crashing bugs with your favorite IDE or developer utility. They're really the only ones who can help you (by fixing the crashing bug) but they can't fix it if they don't know about it. For Apple stuff, use http://bugreport.apple.com

I encountered this when I had some wrong values/type in the info.plist. In particular I had a Icon file key pointing to an Array type which is wrong (should be a String type). If you have made any changes to the info.plist I suggest you can revert to the last saved version to troubleshoot further.

Hopefully this will help someone. I am getting the same error after turning off the dialog that warns you about already running instances when you click "run".

Basically, If I don't shut down previously running instances now by hitting "Stop", I get this error when trying to run.

Took me a while to figure out, but saved me from having to reinstall XCode.

Most often when I come across this issue there is an invalid file reference in my project. Typically references to file(s) in another Xcode project. If you go to the project browser, check for files that (in my case) show just a file icon, no file name. Delete those references, quit Xcode and restart it. Not sure what happens to cause this but this usually does the trick for me. Also, trying to edit the project.pbxproj file in the xcodeproj package contents causes more harm than good. Should be able to fix things to though.

It happened to me the other day when I moved the ipa I created for Testflight (beta testing). After I copied it back, it no longer gave me the error. So apparently moving any files in the project folder can cause this error.
