Xcode crashes when I try to create a outlet from a UIWebview to Header file

Question

I am currently using Xcode 5 on my Macbook Pro which is running OSX Yosemite. I am trying to create an outlet from a UIWebview to a header file. When I let go of my mouse to create the connection, Xcode freezes and crashes. This is repeatedly happening no matter what I have done. I have tried restarting Xcode and my Macbook. Does anyone else have this problem or know how to fix it? Thanks!

I have added the logs from the crash(I couldn't include the backtrace because it exceeded the maximum characters in the body)

Solution

I think you should declare a IBOutlet in your header file. And then in Storyboard you try to connect the header file.

maybe you can download a sample project from apple, if the sample project also crashes, then it's not your code's bug.

Although not the best thing to do, at least this worked for me.

I'ts a nice workaround, voted up as keeps me from opening both xcodes for this
