I've seen various queries here on splitting a Swift string. But they always deal with using either a single character or one of a set of individual characters to split the string. How do I split one string with another? For example, what if I want to split on CR-LF? The analogous Sequence/Collection interfaces have the same problem, I can split on a single Element value, or one of a set of Element values, but not on a specific sub-sequence (actually, sub-collection since the value needs to be repeatedly visitable).
Is there some methods I'm missing? Or do I have to manually search by looping through the receiver Sequence finding the first element of the matching Collection, then return only if the rest of the collection is found at that sequence point?
