Bulls Eye from iOS apprentice 5

I was working my way through Bull’s Eye (in the v5 book (with the dolphin)) and got to the end with the webView. I think I typed in exactly what the book said…then I found the source code that you included and copied that in. But when I try to test, I get a “Build Failed” with this:

Hm…will you see that? It says: “Code Sign Error”
Then "Comand /usr/bin/codesign failed with exit code 1

I know that the Xcode kit has changed once or twice… so maybe it’s changed again. But, nonetheless, I’m stumped.

Thanks for any help.

I probably put this in the wrong area. Will repost it in the “books” forum.
