I found this article on zipping a directory using NSFileCoordinator, without any third party frameworks.

While this approach works, how can we unzip an archive without using third party libraries? I've tried searching for it, but found no solution. If this task isn't possible, is there any documentation/evidence that highlights the same?

CodePudding user response：

Third-party libraries are created by people, which means you indeed can write "unzipping" code yourself, without third-party frameworks. :)

As stated by an Apple engineer on the Apple Developer Forums, there's no simple native solution (like a method somewhere in the Foundation framework or somewhere else), so you need to write your own or rely on an existing third-party library. (The answer on the forum was also marked as recommended by Apple.)
