Swift Collections is out with some new collection-oriented extensions on the Swift language as a companion to Swift Algorithms and Swift Numerics.
π Introducing Swift Collections | github
Swift Collections gives you hybrid collection types like Deque, which is an array with “efficient insertions and removals at both ends”, OrderedSet, which is a “powerful hybrid of an Array and a Set”, and OrderedDictionary (like the actual dictionary).
And of course, they’re efficient. Now go forth and collect in new ways!
