xcode error when using old library

Question

I update my Mac to 1.9.4 and install Xcode 6, I created a new project and copy UIBubbleTable source from the project which I used this library before and still work fine according to my last time check.

The old project works fine with this library, but new project gets error.

I've added every requires framework but still error.

Here are my error logs, please help.

Answer 1

It looks like that library expects a .pch file which imports UIKit/UIKit.h (see UIBubbleTableViewExample-Prefix.pch in the example directory). You can either add a similar pch file to your project. Or you can add the following to the header files where you are seeing those errors:

#import <UIKit/UIKit.h>
