Undefined Symbols Error - NewsYC iOS App - objective-c

Question

I'm trying to build the NewsYC iOS app. I can get it to work in the simulator, but when I target my iPhone 5 I get an undefined symbols errors. I'm pretty new to XCode and Objective C so I'm not really sure how to resolve this. I've done some reading about this error in terms of other projects and have the libHNKit linked in the build phases. Not really sure what else needs to happen to correct this.
This is the error:
ld: warning: ignoring file /Users/stephenwalker/Library/Developer/Xcode/DerivedData/newsyc-gidnwqwyaspbjdevgkudlemjssmd/Build/Products/Debug-iphoneos/libHNKit.a, file was built for archive which is not the architecture being linked (armv7): /Users/stephenwalker/Library/Developer/Xcode/DerivedData/newsyc-gidnwqwyaspbjdevgkudlemjssmd/Build/Products/Debug-iphoneos/libHNKit.a

Answer 1

After doing git submodule init; git submodule update from Terminal, select HNKit.xcocdeproj in the newsyc project's file navigator. Then click "Build Settings", and then you should see "Multiple Values" next to "Build Active Architecture Only". Click that and set it to "NO".
