I had this same problem. My app links to a .framework, and my framework had the SKIP_INSTALL build setting set to YES. Changing it to NO fixed it.

This crash occurred due to problem in my project, so i was beginner, and I assumed that problem is in my X-Code.
The Project loaded automatically and causes crash to occur.
After opening some one previous project, and tried to stop this crashed project, Crashing stopped.. :P
I have an XCode project that compiles and runs fine but when I add an element to the UI of a particular XIB it crashes XCode when I try to save or when XCode loses focus. Looking at the error data of the crash it seems to be an Assertion Failure relating to an NSTableHeader but I don't understand where to go from there? I am not using auto-layout and this is an OSX app.

I am having a similar problem, and I think it is because my XIB files are quite old (from XCode 4.6 or older). There was a major change in the xml-schema since then. (See this article.) I was able to make the change to my XIB I needed to make by fishing XCode 6 out of Time Machine and copying alongside XCode 7 in Applications. I have not attempted to open any projects with XCode 6, but I opened the XIB directly and made the change I needed to make outside the project.
What's weird is that I was able to modify one of these XIB files only a couple of weeks ago. XCode (7) then completely rewrote the XML with the new schema, and it now has no problem editing that XIB. Also, even XCode 6 crashes now if I try to upgrade an XIB to a newer schema. (I guess I can only edit my XIB because XCode 6, unlike XCode 7, can still edit the old schema without upgrading it.)
I think Apple may have introduced a software update in the last couple of weeks that is external to XCode but nevertheless broke the xml upgrade. Or else something else I've done did it, but I can't think what it could be.
FWIW: I'm on 10.11.5, so at least the Interface Builder part of XCode 6 still works on the latest OS.
EDIT: I was able to upgrade the XML and thus be able to edit XIB in XCode 7.3.1 using a slightly more involved solution:
Use Fusion or Parallels to create a 10.8 virtual.
Install XCode 5.1.1 in the virtual. (You can find download links here.)
Open the XIB in XCode 5.1.1 and upgrade it. You will now be able to open it and save it in XCode 7.
I updated Xcode to the latest version via the App Store, as it normal.
I am unable to open any existing project.
I have deleted all Derived Data and have restarted my laptop. Still crashing. And, I have no 3rd party plug ins.
I am including most of the dump. Didn't include the binary images data.
It appears that it might be related to the interface builder. The one app that I want to open, has the Storyboard as the foremost tab.
Thanks for any help in solving this.

I fixed this by fixing another issue. OS X app store kept crashing on installation of 10.10. Solved it by downloading 10.10 from Apple directly.
Then, the issue with Xcode just simply went away! And, now app store app works right. Must have been some corruption in the app store itself.
I have an existing App which works fine for others with Xcode 4.0. I have Xcode 4.02 and xcode crashes as soon as I open this app. At times, it just hangs up and I have to 'Force Quit' Xcode. Other times, it gives me a 'Internal logic error' window and shows the following error.

I have recently upgraded Xcode from version 3 to 4.02. I have tested a couple of other projects and they seem to run fine on 4.02. So, I know that Xcode is installed properly. Please help me figure out what am I doing wrong.
I've seen several references to the same problem that all pointed back to the answer to this question that suggests deleting the repository from Organizer.
Why do I get this assertion failure? I am using Xcode 3.1.2.

I ran into this problem too and found that my issue related to the following configuration settings:
CONFIGURATION_BUILD_DIR = $(BUILD_DIR)/release/bin
CONFIGURATION_TEMP_DIR = build/$(CONFIGURATION_BUILD_DIR)
I removed the settings, just as a test, and the error that Xcode was producing went away.
This looks like XCode is crashing trying to build your application.
Judging by the method names in the traceback, it's looking at dependencies trying to figure out what to build. You might be able to work around the problem by doing a "clean all targets" and trying again.
You might also want to file a bug report at http://developer.apple.com/bugreporter/
