I\'m having a really tough time getting XMPPFramework to work. I\'ve followed every direction written on the net, and XCode is not finding any of my XMPPFramework classes.>
At the XMPPFramework gitHub wiki 1 there is a step by step instruction that helps setting up XMPPFramework for your project.
In fact the error you have mentioned is close to what is also indicated by the instructions.
"However, upon importing an XMPPFramework class, such as by calling '#import XMPP.h' will cause XCode to show an error 'XMPP.h' not found. It appears that XCode is not finding any of the XMPPFramework files."
I hope this gives you enough information to solve this issue you are facing, even though the instructions are not targeted specifically to iOS-5.
