After upgrading to XCode 5, I can no longer add project dependancies to an XCode project. Projects created with XCode 4 preserve the dependancies but don't accept new dependancies. Projects created with XCode 5 don't accept new dependancies at all. And because an image is worth a thousand words...
This is what happens when I have done drag and drop a Child Project to the Parent Project:

As you can see the Child Project is added but it doesn't link to the parent. If I click on it, it displays a blank content, like it can find no more.
Any ideas why is this happening?
Thanks!!!!
