:package: Installation

CocoaPods

CocoaPods is the dependency manager for Swift and Objective-C Cocoa projects. It has over ten thousand libraries and can help you scale your projects elegantly.

Add this to your Podfile:

use_frameworks!

pod 'SwiftLCS'

Carthage

Carthage builds your dependencies and provides you with binary frameworks, but you retain full control over your project structure and setup.

Add this to your Cartfile:

github "Frugghi/SwiftLCS"

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

Add SwiftLCS to your Package.swift dependencies:

import PackageDescription

let package = Package(
    dependencies: [
        .Package(url: "https://github.com/Frugghi/SwiftLCS.git", majorVersion: 1, minor: 3)
    ]
)

Manual

Include SwiftLCS.swift into your project.

:book: Documentation

The API documentation is available here.

:computer: Usage

Import the framework:

import SwiftLCS

String

let x = "abracadabra"
let y = "yabbadabbadoo"

let z = x.longestCommonSubsequence(y) // abadaba

Array

let x = [1, 2, 3, 4, 5, 6, 7]
let y = [8, 9, 2, 10, 4, 11, 6, 12]

let z = x.longestCommonSubsequence(y) // [2, 4, 6]

Indexes

let x = [1, 2, 3, 4, 5, 6, 7]
let y = [8, 9, 2, 10, 4, 11, 6, 12]

let diff = x.diff(y)
// diff.commonIndexes: [1, 3, 5]
// diff.addedIndexes: [0, 1, 3, 5, 7]
// diff.removedIndexes: [0, 2, 4, 6]

:warning: Objective-C

Object comparison of Objective-C objects is done through the isEquals: method, so be sure that the implementations is correct otherwise SwiftLCS will not return the correct indexes.
