GzipSwift

GzipSwift is a framework with an extension of Data written in Swift. It enables compress/decompress gzip using zlib.

Usage

import Gzip

// gzip
let compressedData: Data = try! data.gzipped()
let optimizedData: Data = try! data.gzipped(level: .bestCompression)

// gunzip
let decompressedData: Data
if data.isGzipped {
    decompressedData = try! data.gunzipped()
} else {
    decompressedData = data
}

GzipSwift is SwiftPM-compatible. To install, add this package to your Package.swift or your Xcode project.

dependencies: [
    .package(name: "Gzip", url: "https://github.com/1024jp/GzipSwift", from: Version(6, 0, 0)),

For Linux

1. Install zlib if you haven’t installed yet:

   $ apt-get install zlib-dev

2. Add this package to your package.swift.

3. If Swift build failed with a linker error:

   • check if libz.so is in your /usr/local/lib
     • if no, reinstall zlib as step (1)
