CocoaLibSpotify crashes the app immediately after Login. NSURL Extensions seem to be missing?

Question

I'm building a new spottily app using cocoaLibSpotify. Immediately after instantiating the session with initializeSharedSessionWithApplicationKey, I call attemptLoginWithUserName with a valid username/password pair. The app then immediately crashes with

+[NSURL urlWithSpotifyLink:]: unrecognized selector sent to class 0x23e826c

libc++abi.dylib: terminate called throwing an exception

So it looks like the NSURL extensions are not being recognised. Any ideas?

Ensure you are importing the header wherever you are using spotify extensions like urlWithSpotifyLink:.

#import "CocoaLibSpotify.h"

Also, as mentioned in the CocoaLibSpotify readme, you need to add the -ObjC and -all_load flags to the "Other Linker Flags" build setting in Xcode.
