I was trying to add the runtime in a new cocos2d-iphone project. I can send you the project if you want. I already sent two zip folders to contact@esotericsoftware.com
I found the e-mail address in other forum posts. If I need to send the files to another e-mail, I'll request you to provide that.
I sent two folders named SpineTest and SpineTest2. Both of them are new cocos2d-iphone project. In the SpineTest project firstly I tried to add the runtime files according to the instructions found in the runtime download page. But the files weren't found by the project when I tried to build that. Later the files were found when I added the files in another way. After that the files were found by the project but the errors found.
In SpineTest2 actually there is almost nothing. This project is representing the runtime files not found condition. In that project I tried to add runtime again following the runtime download page instruction but failed. I just added this project to show you the failure of adding runtime to that.
Thanks a lot again badlogic for having such time for me.
