Codesign: What are unsealed contents?

Question

I have just upgraded to XCode 6 and tried to build my Developer ID signed Mac app. However, I now get the following codesign error:

unsealed contents present         


        

Answer 1

I ran into a similar issue today... my error was "unsealed contents present in the bundle root". The fix for me was to remove the custom icon I had on on my app. AppName.app/Icon? was corrupt somehow...
