Creating iOS Framework - iphone

Question

I was trying to create an iOS Framework using This Guide. I did all the things in the same way as mentioned in the tutorial but now when I'm trying to use that Framework into my sample project, I'm getting the following error.

Please tell me what am I doing wrong?

Are you perhaps using #include instead of #import somewhere?
The end result of the problem is that you including this file twice somewhere
