CMMotionManager link error

Undefined symbols for architecture armv7:
   "_OBJC_CLASS_ $ _CMMotionManager", Referenced from:
       objc-class-ref in libQCAR.a (libQCAR.a-armv7-master.o)

Thank you for your reply
 
I understand about the "CoreMotion".
In this matter, Is that what you want without the need to add anything to the understanding that the info.plist to "Required device capabilities"?

Hi nobu,

Yes it needs the CoreMotion framework, as highlighted here:
