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


## Usage

```swift
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
}
```


## Installation

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

```swift
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:

    ```bash
    $ 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`
