Swift ZIPFoundation extract string in memory is not working

Question

I am using ZipFoundation in Swift from https://github.com/weichsel/ZIPFoundation

My requirement is unzip the file contents in memory and directly convert into String.

let archive = Archive(url: fileUrl, accessMode: .read, preferredEncoding: .utf8)
do{
   try archive?.extract(entry, consumer: {data in
      print(data.count)
    })
  }catch{}

The archive object is always null its not reading zip file. Also what is the entry object to pass to extract method?

ZIP Foundation archives support subscripting. This allows you to obtain an Entry by subscripting into an Archive via archive["path/to/file.txt"].

To get access to the contents of the obtained file, you use the closure-based version of extract as follows:

guard let archiveURL = Bundle.main.url(forResource: "archive", withExtension: "zip"),
      let archive = Archive(url: archiveURL, accessMode: .read),
      let entry = archive["test/data.random"]
else { return }

_ = try? archive.extract(entry) { data in
    print(data.count)
}
