Core Image face detection broken on 64 bit iOS?

Question

So, I have an app that uses the face detection feature of Core Image ( https://itunes.apple.com/us/app/ace-freakyface-cartoon-mask/id454513332?mt=8 ) and I just got the new iPhone 5s and the app no longer detects a face. I'm also receiving an error in the console while debugging:

/System/Library/PrivateFrameworks/FaceCore.framework/fcl-fc-3.dat: mach-o, but wrong architecture 2013-09-25 20:17:22.861 faceMaker[474:a16b] Face detection finding face error: Error Domain=FCRFaceDetectorErrorDomain Code=2 "dlopen(/System/Library/PrivateFrameworks/FaceCore.framework/fcl-fc-3.dat, 2): no suitable image found. Did find:

I've update my iPhone 4s(non-64 bit) with iOS 7 and the app works as it should. I think I need to update the valid architectures but when I do that I break the AdMob library. there may be a way around this but not that I'm aware of. Anyway I'm going to keep trying stuff but was wondering if anyone else had similar problems. I also downloaded what looked to be other apps in the app store using the face detector api and the same result, i.e. no joy on 64 bit.

Thanks,

Nick

I also had this issue with our face morphing app. I wrote a stand alone testing program, that only does face recognition software. If I compiled it as a 64 bit app and ran it on the iPhone 5S with iOS 7, it worked. If I compiled it as a 32 bit app ran it on the iPhone 5S with iOS 7, it failed. I received similar log. It appears when in 32 bit mode, a private library named FaceCore is not available. A 64 bit version of the library is available. We need to have more people complain to Apple about this, since it sounds like a OS bug!
