Hi swift-users,
Is it possible to “extract” the `tuple` tuple in the following code directly into two `Int` variables (`tuple` is of type `(Int, Int)`)?
let a = [0,1,2,3,4,5,6,7,8,9]
let b = [0,1,2,3,4,5,6,7,8,9]
let c = zip(a,b).reduce(0) { acc, tuple in
acc + tuple.0 + tuple.1
}
Like so (does not compile):
let d = zip(a,b).reduce(0) { acc, (value1, value2) in
acc + value1 + value2
}
My problem with the current approach is that is makes the calculation very unreadable / not comprehensible (i.e. `.0` and `.1` - my actual calculation and parameters are a bit more complicated). A workaround is to declare two local variables:
let e = zip(a,b).reduce(0) { acc, tuple in
let value1 = tuple.0
let value2 = tuple.1
return acc + value1 + value2
}
Is this intentionally not supported?
Thanks,
- Dennis
