Re: [swift-evolution] Proposal: Filter split extension on Sequence to return tuple of sequences that meet criteria and that do not

This reminds me of something: I *very* often wish the standard library had an analog to `NSIndexSet`. I bring it up b/c it would allow, here, for IMHO a rather nice way to write the *eager* variant of this `filterSplit` (or preferably imho, `partition`, if not for the *other* `partition` out

Re: [swift-evolution] Proposal: Filter split extension on Sequence to return tuple of sequences that meet criteria and that do not

Agree with the name. Also, the implementation could be better at Sequence level rather than specific to Array, just like filter On Wed, Jun 8, 2016 at 11:54 PM, Thorsten Seitz wrote: > +1 from me for adding this method to the standard library. > I would prefer the name

+1 from me for adding this method to the standard library. I would prefer the name `partition(by:)` for it, though, under which I know it from other languages and which is quite fitting, I think. -Thorsten > Am 08.06.2016 um 22:59 schrieb gadiraju praneeth via swift-evolution >

I implemented something similar with two filters initially, but because of 2N vs N I changed it On Wednesday, June 8, 2016, Dave Abrahams via swift-evolution < swift-evolution@swift.org> wrote: > > on Wed Jun 08 2016, Nate Cook wrote: > > >> On Jun 8, 2016, at 3:40 PM, Dave Abrahams via

Its values.filterSplit { $0 % 2 == 0 } in this case On Wed, Jun 8, 2016 at 3:59 PM, gadiraju praneeth < praneethgadir...@gmail.com> wrote: > I added an extension to do this, something like this: > > extension Array { > > func filterSplit(includeElement: (Element) -> Bool) -> ([Element], >

Re: [swift-evolution] Proposal: Filter split extension on Sequence to return tuple of sequences that meet criteria and that do not

I added an extension to do this, something like this: extension Array { func filterSplit(includeElement: (Element) -> Bool) -> ([Element], [Element]) { var elementsSatisfyingCondition = [Element]() var elementsNotSatisfyingCondition = [Element]() self.forEach {

[swift-evolution] Proposal: Filter split extension on Sequence to return tuple of sequences that meet criteria and that do not

Many times, I came across a scenario where I had to filter an array with a condition and filter the same array with opposite of that condition. For example: let values = [2, 4, 3, 5, 6, 9] let divisibleByTwo = values.filter { $0 % 2 == 0 } let notDivisibleByTwo = values.filter { $0 % 2 != 0 }
