问题
Im working on a game I did create in Xcode 4.6 with storyboards. A few weeks ago I opened it in Xcode5 and it worked fine. I was asked to upgrade storyboard and it worked fine. Its not a complex storyboard, only 4 scenes and all standard stuff. Today I went in to try and open it again and xcode hangs and beach balls. I have to force quit it and I do get a very large report which I have saved in a text file but would be too long to post here.
How do I even find out what is causing the problem more specifically in order to ask or google around for an answer?
Things Ive tried: I have disabled source control I cant select the storyboard in order to see the IB Document opens in version, because it hangs.
I think this is the relevant part of the crash report:
Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000

You may have to disable autolayout manually in the storyboard. Right-click the storyboard -> Open As -> Source Code. Find useAutolayout="YES" and change it to useAutolayout="NO".
This may only work with Mavericks OS and XCode 5.0.2. XCode 5.0.2 has several "occasionally hangs" bug fixes.

Well, this is what I did.
I opened up the Storyboard file from Finder, in TextEdit, saw the Autolayout property and decided to set it to
NO. I did this because I remember skimming through the Crash report, seeing something about constraints.Then I opened the Storyboard from Finder, but this time in Xcode5. It opened up the storyboard scenes but all scenes were pretty much blank. Meaning I couldn't see any controls that were originally there. I thought this was due to removing autolayout. So I re-added the key
useAutolayout="YES"into the xml in TextEdit. Then I opened up the Storyboard file again, in Xcode5 and it was still blank.Then I decided that perhaps I needed to open the entire project in XCode5 to see if the controls were still there. I did but I still didn't SEE the controls, but in the Scene navigator I could expand the nodes and those controls appeared to be in there.
Finally I resolved each AL issue individually and now the storyboard items have reappeared.
