Re: [swift-users] Need better name, want to hide generator

1. Maybe ProductGenerator? 2. Use AnyGenerator<(T, U)>? I'd love to see something like this in stdlib: func product(s1: S1, s2: S2) -> ProductSequence { ... } where ProductSequence.Generator.Element is (T, U). So your example could

Re: [swift-users] Design and performance of Vector2/3/4 and Matrix

You will also want to have this code in the same module that is using this type. If you're using these types from another module you're limited to unspecialized generics which are (unsurprisingly) very slow. I assume these types are intended for your SwiftGL library. If they are only for

Re: [swift-users] Design and performance of Vector2/3/4 and Matrix

Do you have the optimizer enabled (using -O)? I see inlining happening as you'd expect. This: let x = Vector2(x: 1, y: 1) foo(x.x) foo(x.r) optimizes down to: %15 = integer_literal $Builtin.Int64, 1 // user: %16 %16 = struct $Int (%15 : $Builtin.Int64)// users: %17, %17,

[swift-users] Need better name, want to hide generator

Source: http://swiftstub.com/788132715 Two questions: 1. Can anyone recommended a better name than Cartesian? 2D doesn't work for the compiler and I'm looking for something that doesn't seem "floating-point"-y 2. Is there a way to internalize the generator and

Re: [swift-users] Need better name, want to hide generator

At a minimum, this gives me http://swiftstub.com/60017598 But I remember reading *somewhere* (can't remember) that we were supposed to avoid AnyGenerator/AnySequence and they were on the way out. Am I out of my mind? -- E > On Dec 18, 2015, at 2:47 PM, Jacob

[swift-users] SwiftRedis

Hi all, Proud to announce 0.0.1 of SwiftRedis, a Swift wrapper around hiredis. It's very early in development but I thought some of you might like to have a crack at it, contribute anything you like, or try using it for some very basic Redis commands! It requires mainline Swift if you're
