Xcode 5 crash when Open storyboard made from Xcode 4.6

Question

I'm working for a project with Xcode 4.6 since 2 mounth ago, now that I want to send to apple my app everything is ok but when I've tried to run the app on iOS 7 I saw some bugs; so I've downloaded the new Xcode 5 for see where are the bugs, but what happened is that when I try to open the storyboard with IB Xcode crash. I try to see in Internet how fix this problem but I don't find anything about that.

Also the error that Xcode give me when i try to run the app on the device with iOS 7 is:

Answer 1

The problem was that I work with 2 Mac in this project and in the Mac where I've installed Xcode 5 I did't install the new font that I had in my project (and that i Used in the storyboard).

So for fix the problem I've just installed the Fonts into the Mac where I get the problem

I answer my question for help someone that will have my same problem!

Answer 2

In Xcode 5 go to Preferences > Source Control > Uncheck the Enable Source control
