Swift Algorithms

Swift Algorithms is an open-source package of sequence and collection algorithms, along with their related types.

Read more about the package, and the intent behind it, in the announcement on swift.org.

Mutating algorithms

Combining collections

  • chained(with:): Concatenates two collections with the same element type.
  • product(_:_:): Iterates over all the pairs of two collections; equivalent to nested for-in loops.
  • cycled(), cycled(times:): Repeats the elements of a collection forever or a set number of times.

Subsetting operations

Other useful operations

  • chunked(by:), chunked(on:): Eager and lazy operations that break a collection into chunks based on either a binary predicate or when the result of a projection changes.
  • indexed(): Iterate over tuples of a collection's indices and elements.

Adding Swift Algorithms as a Dependency

To use the Algorithms library in a SwiftPM project, add the following line to the dependencies in your Package.swift file:

.package(url: "https://github.com/apple/swift-algorithms", from: "0.0.1"),

Because Algorithms is under active development, source-stability is only guaranteed within minor versions (e.g. between 0.0.3 and 0.0.4). If you don't want potentially source-breaking package updates, use this dependency specification instead:

.package(url: "https://github.com/apple/swift-algorithms", .upToNextMinor(from: "0.0.1")),

Finally, include "Algorithms" as a dependency for your executable target:

let package = Package(
    // name, platforms, products, etc.
    dependencies: [
        .package(url: "https://github.com/apple/swift-algorithms", from: "0.0.1"),
        // other dependencies
    ],
    targets: [
        .target(name: "<target>", dependencies: [
            .product(name: "Algorithms", package: "swift-algorithms"),
        ]),
        // other targets
    ]
)
