Zip

A Swift 4.0 framework for zipping and unzipping files. Simple and quick to use. Built on top of minizip.

Fork

This is a fork of https://github.com/marmelroy/Zip merging marmelroy#155. I will maintain this until upstream returns, in the mean time pull requests are welcome.

Usage

Import Zip at the top of the Swift file.

import Zip

Quick functions

The easiest way to use Zip is through quick functions. Both take local file paths as NSURLs, throw if an error is encountered and return an NSURL to the destination if successful.

do {
    let filePath = Bundle.main.url(forResource: "file", withExtension: "zip")!
    let unzipDirectory = try Zip.quickUnzipFile(filePath) // Unzip
    let zipFilePath = try Zip.quickZipFiles([filePath], fileName: "archive") // Zip
}
catch {
  print("Something went wrong")
}

Advanced Zip

For more advanced usage, Zip has functions that let you set custom destination paths, work with password protected zips and use a progress handling closure. These functions throw if there is an error but don't return.

do {
    let filePath = Bundle.main.url(forResource: "file", withExtension: "zip")!
    let documentsDirectory = FileManager.default.urls(for:.documentDirectory, in: .userDomainMask)[0]
    try Zip.unzipFile(filePath, destination: documentsDirectory, overwrite: true, password: "password", progress: { (progress) -> () in
        print(progress)
    }) // Unzip

    let zipFilePath = documentsFolder.appendingPathComponent("archive.zip")
    try Zip.zipFiles([filePath], zipFilePath: zipFilePath, password: "password", progress: { (progress) -> () in
        print(progress)
    }) //Zip

}
catch {
  print("Something went wrong")
}

Custom File Extensions

Zip supports '.zip' and '.cbz' files out of the box. To support additional zip-derivative file extensions:

Zip.addCustomFileExtension("file-extension-here")

Setting up with CocoaPods

source 'https://github.com/CocoaPods/Specs.git'
pod 'Zip', '~> 1.1'

Setting up with Carthage

To integrate Zip into your Xcode project using Carthage, specify it in your Cartfile:

github "marmelroy/Zip" ~> 1.1

Setting up with Swift Package Manager

To use Zip with Swift Package Manager, add it to your package's dependencies:

.package(url: "https://github.com/marmelroy/Zip.git", .upToNextMinor(from: "1.1.0"))
