Avoiding Swift’s enumerated()
The integer value we get with
enumerated()shouldn’t be used as index into the collection unless the collection is zero-based and integer-indexed. It’s a counter that always starts from zero.
zipis better in every way… even when you just want numbers
zip(0…, ingredients)is clearer which way around the pair is
zip(1…, ingredients)if you don’t want to keep doing +1 on a zero base
Another subtlety is:
collection.reversed().enumerated()vs
collection.enumerated().reversed()
If you’re using swift-algorithms, you can also use
.indexed()for a slightly better interface thanzip.
