try ZipUtilities.compressFile(at: fileURL, to: destinationURL)

// Compress a directory
try ZipUtilities.compressDirectory(at: directoryURL, to: destinationURL)


To decompress a zip archive, use the following code:

// Import the ZipUtilities module
import ZipUtilities

// Decompress a zip archive
try ZipUtilities.decompressFile(at: zipURL, to: destinationURL)

Zip Archive Management

ZipUtilities provides various methods to work with zip archives:

// Import the ZipUtilities module
import ZipUtilities

// Get the list of files and directories within a zip archive
let fileList = try ZipUtilities.contentsOfArchive(at: archiveURL)

// Check if a file exists within a zip archive
let fileExists = try ZipUtilities.fileExists(withinArchive: archiveURL, filePath: "path/to/file.txt")

// Extract a specific file from a zip archive
try ZipUtilities.extractFile(fromArchive: archiveURL, filePath: "path/to/file.txt", to: destinationURL)

// Password protect a zip archive
try ZipUtilities.setPassword("secretPassword", forArchive: archiveURL)

// Check if a zip archive is password protected
let isPasswordProtected = try ZipUtilities.isPasswordProtected(at: archiveURL)

Progress Tracking

To track the progress of a zip operation, you can implement the ZipUtilitiesProgressDelegate protocol and assign a delegate to observe the progress:

// Import the ZipUtilities module
import ZipUtilities

// Assign a delegate to track the progress
ZipUtilities.progressDelegate = self

// Implement the ZipUtilitiesProgressDelegate protocol methods
class YourViewController: UIViewController, ZipUtilitiesProgressDelegate {
    func zipProgressDidChange(progress: Double) {
        print("Zip operation progress: \(progress * 100)%")
    // ...

Zip64 Support

ZipUtilities offers support for the Zip64 format, which allows handling large zip archives exceeding the traditional size limit. For operations involving Zip64 archives, use the provided methods:

// Import the ZipUtilities module
import ZipUtilities

// Compress a file using Zip64 format
try ZipUtilities.compressFile(at: fileURL, to: destinationURL, useZip64: true)

// Check if a zip archive is Zip64 format
let isZip64Format = try ZipUtilities.isZip64Format(at: archiveURL)

Supported File Formats

ZipUtilities supports both the zip and gz file formats for compression and decompression operations.


ZipUtilities is a valuable library for any iOS developer looking to handle zip archives in their applications seamlessly. Its powerful features, ease of use, and exceptional performance make it an ideal choice for managing compressed files efficiently.
