How to check if a framework is Bitcode supported for Xcode7

by

From this Apple Developers Forum discussion, user dshirley and bwilson suggest using command line tools otool and grep to check if bitcode sections exist. 

$ otool -l libName.o | grep __LLVM

or

$ otool -l MyFramework.framework/Versions/A/MyFramework | grep __LLVM

Running the above command, if the library contains bitcode you will see segname __LLVM output.
