In Xcode 6.1 , I am getting error for iPhone 6, iPhone 5s(iOS 7.1) which says
Undefined symbols for architecture x86_64:
\"_OBJC_CLASS_$_ClientAut
I run into exactly the same problem and was following this tutorial https://github.com/jverkoey/iOS-Framework#faq
The way that I made this work is after putting into the scripts into your Aggregate's Build Phase, before you compile, make sure you compile it using an iphone simulator (I used iPhone6) instead of IOS Device.
which will give me 2 slices: armv7 and x86_64, then drag and drop it into new project is working fine for me.
