@chirag225 @slavavdovichenko I am experiencing the same issue.. The code line which if I add I get the duplicate symbol issue. I have checked the above comments and checked that all are included.

MPMediaDecoder *decoder = [[MPMediaDecoder alloc] initWithView:previewView]; Another thing I get to know that its suggested to add CoreData.framework in the page however in this screenshot in above comment, its not getting shown. Why so?

Please help me out!!!

I am using Xcode 6.4 thats why I have used .dylib file instead of tbd file. I am getting the below errors.

I got the issue its because of the tbd file I am not using because I am working on the Xcode 6.4. @slavavdovichenko how can I use Xcode 6.4 to use this library????

Hi,

You can get the older version from http://www.themidnightcoders.com/download.html (3.3.1). But maybe it is better to upgrade the Xcode?
