Sphero iOS SDK v1.6 - Linker Error

Question

I'm trying to set up the iOS SDK that was pushed out today, and I'm getting a few linker errors. I changed my deployment target to iOS 7.0 and got a lot of linker errors, then changed it to 6.0 and got a few linker errors, so I stuck with iOS 6.0. Here is my output

Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_RKMCStop", referenced from:
      objc-class-ref in RobotKit(RKMacroObject.o)
  "_OBJC_CLASS_$_RKMCWaitUntilStop", referenced from:
      objc-class-ref in RobotKit(RKMacroObject.o)
      objc-class-ref in RobotKit(RKRobotControl+MacroAdditions.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've double checked my linker flags and attached libraries, and can't find anything out of the ordinary. I'm putting this over a previous project that was set up and working with the previous libraries.

Seams that your are using a library that is not valid for armv7.

Under Xcode -> Build Settings -> Architectures check the property "Valid Architectures"

You have armv7 there try to use armv6 instead.

Also this problem can be related if you are using a framework that is not available into the list of your frameworks anymore, or a Library that is not linked (Check the Library Search Path) in that case
