App crashes when calling NSDate Collection methods

[dingua]

The application launched from XCode 5 used to crash on every NSDate collection method.
The log of crash is :"[__NSDate mn_beginningOfDay:]: unrecognized selector sent to instance"
Is it related to project integration on XCode 5?

I don't have this issue on XCode5, is this still an issue for your?

Yes, issue doesn't exist, i still have problem of integration of your framework in my project.. but it is caused by our project configuration. I used pods for framework integration .This works when making it with a new empty project but with my working project i still have the same problem.
Do you have an idea what means this crash? Because it compiles well, but once i call any method of your framework's classes it crashes.
Thanks.

@dingua you have to add MKCalendarView files to dedicated group of project's sources. Don't add it as a framework, just add files to project as i showed in screenshot.

Your problem causes because MKCalendar extends NSDate object with some methods. So your project can not resolve this methods.
