Undefined symbols for architecture i386:
"OBJC_CLASS$_DDLog", referenced from:
objc-class-ref in libNine00SecondsSDK.a(libNine00SecondsSDK.a-i386-master.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Please, provide a solution to fix this.

I fixed this by adding CocoaLumberjack and CocoaLumberjackSwift to the Linked Frameworks and Libraries under the project's TARGETS. I added these through Carthage.
