A super easy way of extracting all or only unique words from an NSString

Extracting unique words would look like this:

NSString *string = @"first_name last_name";
NSSet *uniqueWords = [string hyp_uniqueWords];

Would produce

uniqueWords: {(
    "first_name",
    "last_name"
)}

Extracting all words would look like this:

NSString *string = @"first_name last_name last_name";
NSArray *words = [string hyp_words];

Would produce

words: (
    "first_name",
    "last_name",
    "last_name"
)
