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

• Requirements: OS X 10.9 / iOS 8 / watchOS 2 / tvOS 9 or later
• Swift version: Swift 3.0.1

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
}

// check data is gzipped
print(compressedData.isGzipped)

1. Build Gzip framework.
2. In Build Phases, add Gzip.framework library to your project.
   
3. import Gzip in your Swift file.
4. Use in your code.

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

github "1024jp/GzipSwift"

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

pod "GzipSwift"

1. First you need to install zlib if you haven't installed yet:

   $ apt-get install zlib-dev

2. add this packge 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
