Do you think we are missing an alternative of SwiftLCS or a related project?
SwitLCS provides an extension of
Collection that finds the indexes of the longest common subsequence with another collection.
The longest common subsequence (LCS) problem is the problem of finding the longest subsequence common to all sequences in a set of sequences (often just two sequences). It differs from problems of finding common substrings: unlike substrings, subsequences are not required to occupy consecutive positions within the original sequences.
The project is based on the Objective-C implementation of NSArray+LongestCommonSubsequence.
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 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:
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.
SwiftLCS to your Package.swift dependencies:
import PackageDescription let package = Package( dependencies: [ .Package(url: "https://github.com/Frugghi/SwiftLCS.git", majorVersion: 1, minor: 3) ] )
SwiftLCS.swift into your project.
The API documentation is available here.
Import the framework:
let x = "abracadabra" let y = "yabbadabbadoo" let z = x.longestCommonSubsequence(y) // abadaba
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]
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]
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.
