 <p>From error description you provided I can see that:</p> <p>During linking phase for Intel 64bit architecture _OBJC_CLASS_$MYFramework symbol was not found. Which is quite strange as you sure you compiling for arm architecture. Maybe you should revise Makefiles of your framework?</p> <p>Have a look <a href="http://stackoverflow.com/questions/18913906/xcode-5-and-ios-7-architecture-and-valid-architectures">here</a> Shell you make target IOS7 32bit?</p>
