I'm trying to figure out how to use the Stride features in Swift.
It seems to have changed again, since Xcode 7.0 beta 6.
Previously I could use
let strideAmount = stride(from: 0, to: items.count, by: splitSize)
let sets = strideAmount.map({ clients[$0..<advance($0, splitSize, items.count)] })
Now, despite the code hint I cannot figure out how to use this feature.
Any examples would be helpful thanks.
I've looked at examples, but I cannot come to grips with how to use it. All I get from the Apple Docs are limited.
Thanks
It changed a bit, here is the new syntax:
0.stride(to: 10, by: 2)
and
Array(0.stride(to: 10, by: 2)) // is [0, 2, 4, 6, 8]
if you take a look at here, you can see what types conform to the Strideable
protocol.
As @RichFox pointed out, in Swift 3.0 the syntax changed back to the original global function form like:
stride(from:0, to: 10, by: 2)
