Xcode crashes when I open a specific XIB file

I had a XIB file which worked fine until today – when I try to open it in Xcode, the beachball appears and after 1 minute Xcode crashes. Others XIBs work just fine. Also, if I just build and run the project right to my device, its also work (and XIB works at the app).

Here is the error message:

  • xcode 5.1 - Undefined symbols for architecture x86_64 (zbar)
  • AVSpeechSynthesizer error AudioSession
  • alternatives to XCode for iPhone development? (OR: how to make XCode suck less?)
  • How can I create a zip file by using Objective C?
  • Strange UIView-Encapsulated-Layout-Height Error
  • Accessing UITextField in a custom UITableViewCell
  • Crashed Thread:  0  Dispatch queue: com.apple.main-thread
    
    Exception Type:  EXC_CRASH (SIGABRT)
    Exception Codes: 0x0000000000000000, 0x0000000000000000

    I will appreciate any ideas and thoughts!

    Are you using the autoLayout Property ? Uncheck the checkbox that says Use AutoLayout and it should work fine. Unchecking this and then saving the file seems to fix the problem for me earlier. check this link for further details Xcode Interface Builder crashes when I edit storyboard

    If Xcode crashes as soon as you click on the xib file, you won’t be able to uncheck Use AutoLayout. Here’s how you can change it:

    1. Right-click on the .xib file in the Project Navigator
    2. Choose Open As… > Source Code
    3. Find this line towards the end: <bool key="IBDocument.UseAutolayout">YES</bool>
    4. Change YES to NO
    5. Save File
    6. Right-click on the .xib file again in the Project Navigator
    7. Choose Open As… > Interface Builder – iOS
