Inserting nil into Array crash

[ajmccall]

HI @dadederk,

When using your pod, we have some crashes being reported LIVE

Fatal Exception: NSInvalidArgumentException
0  CoreFoundation                 0x181482db0 __exceptionPreprocess
1  libobjc.A.dylib                0x180ae7f80 objc_exception_throw

I suspect that the user is swiping quickly and the current card index is beyond the number of cards.

Might be solved by #2

@ajmccall I have merged #2 and created a new version of the pod. Looking good, but let's keep the Issue opened for the moment and see if the fix takes effect?
