I can't run my application cause of this crazy error. Everything ran great before I updated from Xcode 6 to 7.
You have to import AVFoundation and AudioToolbox frameworks and also set i386 armv6 armv7 armv7s architectures needed for running the libraries.
OR
The 7 frameworks need to be in the following order:
Foundation.framework
CoreGraphics.framework
UIKit.framework
AVFoundation.framework
CoreMedia.framework
CoreVideo.framework
QuartzCore.framework
libiconv.dylib
libzbar.a
I wasn't aware the order the frameworks are declared in the Build Phases mattered. Anyways, hopefully for anybody trying to integrate a barcode scanner into their app, this answer will be useful.
