I had a similar though some time ago (and even suggested it here) - as e.g. "Hello".components(separatedBy: "123") will always produce a non-empty array. Even "".components(separatedBy: "") is [""].
Which would allow e.g. first, last and some other members to loose the optionality - which would be great. But would probably add unnecessary complexity to the stdlib. Fixed-size arrays do not solve this particular issue that I've noted above. > On Aug 8, 2017, at 1:39 PM, Tino Heth via swift-evolution > <swift-evolution@swift.org> wrote: > > I think it would make sense to have arrays with a minimal size, but wouldn't > consider it very important. > But there is a long-running discussion about fixed-size arrays, and depending > on (if any) solution is chosen for them, your use case could be solved rather > easy as well. > _______________________________________________ > swift-evolution mailing list > swift-evolution@swift.org > https://lists.swift.org/mailman/listinfo/swift-evolution _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
