OCMock with Swift Package Manager

[ajpallares]

Fixes #335.

Note that because OCMock contains unsafeOptions, the dependency of OCMock has to be specified by a commit hash (see erikdoe/ocmock#460 (comment)).

I'm mostly new to SPM and curious as to how it works, so please excuse my questions if they seem too stupid. As for the #if directives, those seem a bit painful for me, especially as I expect to not get a feedback that I forgot one until after I try to do some SPM work, correct?

However, I do appreciate the PR and want to add support for SPM, I wouldn't want to block anyone from switching to their dependency manager of choice. Thanks for tackling this!

Don't worry! I'm also rather new to SPM but the good thing about this is that we learn from it 😊

In any case, I didn't find any of your questions to be stupid at all! I think it's a good thing that you care a lot about this library and that you require minimum quality standards.

Totally agree. They are painful and easy to be forgotten in the future.

No problem. We'll get it working for sure. I'm already using Cuckoo with SPM in our project but I needed to add some ObjC mocks and the straightforward solution is to use Cuckoo + OCMock. So thank you for this amazing library! 🙌

Merged! Thanks a lot, @ajpallares, for this great PR and the research that you've put into making Cuckoo+OCMock work with SPM. 🙂
