I just upgraded to Xcode 8.2.1 and Xcode crashes every time I open my project with the following traceback. I verified that an older version of Xcode (8.1) can still open the project file. Any help would be greatly appreciated.

Exception Type:        EXC_CRASH (SIGABRT)
Exception Codes:       0x0000000000000000, 0x0000000000000000
Exception Note:        EXC_CORPSE_NOTIFY

    For me...deleting Derived Data content worked! – Jayprakash Dubey Feb 1 '17 at 7:21
  • @JayprakashDubey It will work until you hit Find Navigator few times and then will crash again, and you will have to clean derived data again and so on... Very buggy release. – Whirlwind Feb 3 '17 at 11:27

Ok, well I managed to fix this issue by deleting my .xcworkspace directory and recreating it via pod install. Xcode opens and I'm able to build my project.

Edit: As others have suggested a better solution is to delete the xcuserdata directory from within .xcworkspace. This is faster as you don't need to re-run pod install every time.

    I was also able to "fix" the issue (after forced into xcode update) by opening the .xcworkspace directory (show pakcage contents) and then get rid of the xcuserdata folder. – Lukasz 'Severiaan' Grela Jan 3 '17 at 14:15
  • Lukasz 'Severiaan' Grela, thanks for your answer. It solved my problem. – ZevsVU Jan 9 '17 at 12:27

The correct answer is from Lukasz's comment:

  1. Right click on the file .xcworkspace > Show Package Contents
  2. Delete the xcuserdata folder

And now Xcode will open the project workspace just fine.

  • This is same as that of @Eric answer – Jayprakash Dubey Feb 1 '17 at 7:21

    @Jayprakash He edited his answer directly after I added this answer. His edit was at 20:17:4 UTC and this answer was posted at 19:52:17 UTC. – ChrisJF Feb 1 '17 at 21:50
  • This might work too. But if the issue returns back after some time (mostly when using Find Navigator). – Whirlwind Feb 3 '17 at 11:31
  • I think you need a 3rd point : 3. Run pod install/update. Thanks – Jordan Montel Feb 10 '17 at 11:16
  • This method works. I tried restart the whole MacOS, but it didn't work. – AechoLiu Feb 21 '17 at 8:14

For others experiencing a similar issue, but this only happens when the Find Navigator is toggled in the navigator area. Try clicking on the Project Navigator or CMD + 1 repeatedly upon launch. Sounds funny but it works.

  • FYI, it may fail the first couple of times. – funct7 Jan 12 '17 at 23:39
  • Yeah, a bit funny, but mostly sad. I am having the same problem and if i don't use Find Navigator, it doesn't crash at all. This version of Xcode, sadly, sucks big time. – Whirlwind Feb 3 '17 at 11:30

Besides deleting the xcuserdata folder in the project's workspace directory, I was also able to remedy this particular crash by deleting derived data (either for the project that was open while Xcode crashed, or for all projects) at ~/Library/Developer/Xcode/DerivedData. Last time Xcode crashed I had to do both things to be able to start Xcode again, so I think deleting both is your safest bet (for now at least).

  • yes deleting xcuserdata helps.
  • I used to wipe the Derived Data but then it would crash again immediately on Reopen if I tried to do anything before indexing finished again.
  • I noticed that it only happened on a personal project I edited at home and in work.
  • The username was different on both so I ended up with 2 user entries in xcuserdata my work login username and my home username.
  • I notice that both have Breakpoints.
  • And the error thrown is _IDENavigatorOutlineViewDataSource so its something on the LHS side panels in Xcode?
  • Can you add a .ignore for xcuserdata without messing up a workspace?
