Include Headers from added frameworks on Xcode

Question

I want to work with some frameworks like glew and cg so i manually added

the needed frameworks to my project by right clicking the project ->

Answer 1

For those whose autocomplete fails after adding framework.

I used to add frameworks, by going to Build Phases and taking the Link Binary with Libraries option. Now in XCode 6.1, though project was building fine, autocomplete in XCode was not working.

So what needs to be done is:

1. Remove the already added framework from Project Navigator and also from Link Binary with Libraries.
2. Add framework to project by simply File -> Add Files to option in XCode.

And auto complete will start working.
