let decompressedData: Data
if data.isGzipped {
    decompressedData = try! data.gunzipped()

Installation

Manual Build

1. Open Gzip.xcodeproj on Xcode and build Gzip framework for your target platform.
2. Append the built Gzip.framework to your project.
3. Go to General pane of the application target in your project. Add Gzip.framework to the Embedded Binaries section.
   
4. import Gzip in your Swift file and use in your code.

Carthage

GzipSwift is Carthage compatible. You can easily build GzipSwift adding the following line to your Cartfile:

github "1024jp/GzipSwift"

CocoaPods

GzipSwift is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'GzipSwift'

Swift Package Manager

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)
     • if yes, link the library manually by passing '-Xlinker -L/usr/local/lib' with swift build
