GitHub - sourcewerk/DataCompression: DataCompression - Swift libcompression wrapper as an extension for the Data type (ZLIB, LZFSE, LZMA, LZ4, deflate, RFC-1950, RFC-1951)

A libcompression wrapper extension for the `Data` type

Supported compression algorithms are:

ZLIB deflate stream RFC-1950
ZLIB deflate raw RFC-1951
LZMA
LZFSE
LZ4

Requirements

iOS deployment target >= 9.0
macOS deployment target >= 10.11
tvOS deployment target >= 9.0
watchOS deployment target >= 2.0

Usage example

    let s = "A string that really needs to loose some weight..."
    var res: Data? = s.data(using: .utf8)

    res = res?.deflate()
    res = res?.inflate()

    res = res?.zip()
    res = res?.unzip()

    res = res?.compress(withAlgorithm: .LZFSE)
    res = res?.decompress(withAlgorithm: .LZFSE)

    res = res?.compress(withAlgorithm: .LZ4)
    res = res?.decompress(withAlgorithm: .LZ4)

    res = res?.compress(withAlgorithm: .LZMA)
    res = res?.decompress(withAlgorithm: .LZMA)

    res = res?.compress(withAlgorithm: .ZLIB)
    res = res?.decompress(withAlgorithm: .ZLIB)

    assert(res != nil)
    let t = String(data: res!, encoding: .utf8)
    assert(s == t)

Install

Cocoa Pods

To integrate DataCompression into your Xcode project using CocoaPods, add it to your Podfile:

target '<your_target_name>' do
    pod 'DataCompression'
end

Then, run the following command:

You then will need to add import DataCompression at the top of your swift source files to use the extension.

Swift Package Manager

To integrate DataCompression into your Xcode project using the swift package manager, add it as a dependency to your Package.swift file:

import PackageDescription

let package = Package(
    name: "<your_package_name>",
    dependencies: [
        .Package(url: "https://github.com/mw99/DataCompression.git", majorVersion: 2)
    ]
)
