Here is frameworks from project: MediaPlayer, AudioToolbox, CoreImage, QuartzCore, ImageIO, CoreMedia, AVFoundation, opencv2, Foundation, CoreGraphics, UIKit — STBY, Jun 02 '14 at 08:54
Did you try this `Go to framework search paths. Remove everything from there`? Also try this too http://stackoverflow.com/questions/19130744/xcode-5-framework-library-search-path-absolute-address. — Mani, Jun 02 '14 at 09:09
Did you try to compile with an iPod or iPhone? It seems that you compile your application with a library which is not supported simulator in the simulator. For example: AVFoundation. Try NSLog(@"%@", [AVCaptureDevice devices]); in simulator, you will see no Device — Duyen-Hoa, Jun 02 '14 at 09:15

Just add CoreMedia.framework and with AVFoundation.framework to your project.

Got to.

Project -> target -> Build phases -> Link binary with library -> "+" -> select your frameworks

Ok... then add which you did not added CoreMedia.framework","AudioToolbox.framework","CoreGraphics.framework","CoreVideo.framework","AVFoundation.framework","libiconv.dylib" – iPatel Jun 02 '14 at 08:55

As suggested by Mani add required frameworks. If you have already added these frameworks and still getting error, set Build Active Architecture Only to NO under project 's Build Settings.
