I have faced problem which describe by ( ChartsDemo-swift.h file not found ) i want to focused that everything is working correctly only this file isn't imported .

actually it should be "yourprojectname-swift.h" if you are using in your project.
also in build phase check "Embedded content contains swift code"s should be yes
Thanks @vishw3
sorry for late but still have the same error
@danielgindi @ahmadabudawod Please see http://stackoverflow.com/a/30648104/277370. When you use embedded framework, I had to do like the answer on SO. Using the #import <project>-Swift.h works well when you directly add the library files (Classes/) to your project (instead of just adding the .xcodeproj and add it to embed frameworks).
I think when you only add the xcodeproj, You must import it with #import "Charts/Charts-Swift.h"
@allaire thumbs up. your solution helped me. I am not sure why, but the previous comments of importing #import
@allaire Thumbs up again. Hey @danielgindi I think the same can be updated for newbies. I was stuck with the same, being newbie to objc-swift bridging. Thanks again @allaire , you saved the day.
@allaire
Xcode 8.1,iOS 10.1, I have this issue.
Thank you for your solution.
put it in .m file and leave a forward declaration in .h
