Question 1

How to unzip a password-protected file in Swift using Zip?

Accepted Answer

Use the advanced unzipFile function with the password parameter, as shown in the README—for example, try Zip.unzipFile(filePath, destination: documentsDirectory, password: "password"). This allows secure extraction with error handling via do-catch blocks.

Question 2

Zip vs Apple's Compression framework for iOS?

Accepted Answer

Zip provides a higher-level, Swift-native API specifically for zip files, making it easier for common tasks like zipping/unzipping with passwords. In contrast, Apple's Compression framework is lower-level, supports various algorithms (e.g., LZ4, LZFSE), but requires more code to handle zip archives directly.

Question 3

How to track progress when zipping multiple files with Zip?

Accepted Answer

Utilize the progress closure in the zipFiles function—for instance, try Zip.zipFiles([filePath], zipFilePath: zipFilePath, progress: { print($0) }). This closure provides real-time updates during compression, helping monitor long-running operations.

Question 4

Does Zip support .cbz files out of the box?

Accepted Answer

Yes, Zip supports .cbz files by default along with .zip, as mentioned in the README under custom file extensions. It handles them seamlessly in quick and advanced functions without additional setup.

Question 5

How to add custom file extension support in Zip framework?

Accepted Answer

Call Zip.addCustomFileExtension("extension") to register additional zip-derivative extensions, such as for specialized formats. This is useful for apps dealing with niche file types but doesn't extend to non-zip archives.

Question 6

Is Zip compatible with Swift Package Manager?

Accepted Answer

Yes, Zip is fully compatible with Swift Package Manager—add it as a dependency in your Package.swift with .package(url: "https://github.com/marmelroy/Zip.git", .upToNextMinor(from: "2.1")), making it easy to integrate in modern Swift projects.
