SE0270_RangeSet is a standalone library that implements the Swift Evolution proposal SE-0270: Add Collection Operations on Noncontiguous Elements. You can use this package independently, or as part of the standard library preview package.
SE0270_RangeSet provides operations on noncontiguous subranges of collections,
such as subranges(where:) and moveSubranges(_:to:),
as well as the supporting RangeSet type.
import SE0270_RangeSet
var numbers = [10, 12, -5, 14, -3, -9, 15]
let negatives = numbers.subranges(where: { $0 < 0 })
// numbers[negatives].count == 3
numbers.moveSubranges(negatives, to: 0)
// numbers == [-5, -3, -9, 10, 12, 14, 15]You can add this library as a dependency to any Swift package.
Add this line to the dependencies parameter in your Package.swift file:
.package(
url: "https://github.com/apple/swift-se0270-range-set",
from: "1.0.0"),Next, add the module as a dependency for your targets that will use the library:
.product(name: "SE0270_RangeSet", package: "swift-se0270-range-set"),You can now use import SE0270_RangeSet to make the library available in any Swift file.
