Looks like there's a failure when attempting to build SwiftZip for the new Apple visionOS:

In file included from /Users/[...]/SwiftZip/Sources/zip/libzip/lib/zip_unchange_archive.c:37:
/Users/[...]/SwiftZip/Sources/zip/libzip/lib/zipint.h:37:10: fatal error: 'config.h' file not found
#include "config.h"
         ^~~~~~~~~~
1 error generated.

Is this just a matter of re-configuring libzip?

Hello,

I have a UICollectionView which has various UICollectionViewCells (usually around 200 cells approx.).

Every cell displays an image that is inside the Zip File.

In order to load the image that's inside the Zip file, I developed this code:

func getPage(name: String, at index: Int, compression: CGFloat) -> UIImage {
        if let cachedImage = ImageCache.shared.object(forKey: "\(name)-\(index)-thumbnail" as NSString) {
            return cachedImage
        } else {
            do {
                let data = try entries[index].data() // <- The error is here
                if let image = UIImage(data: data)?.resized(withPercentage: compression) {
                    ImageCache.shared.setObject(image, forKey: "\(name)-\(index)-thumbnail" as NSString)
                    return image
                } else {
                    return UIImage()
                }
            } catch let error {
                print("Error getting page: \(error)")
                return UIImage()
            }
        }
    }

`func cellForPage(at indexPath: IndexPath) -> UICollectionViewCell {
    let cell = mainCV.dequeueReusableCell(withReuseIdentifier: kSmallPageCVC, for: indexPath) as! SmallPageCVC
    DispatchQueue.global(qos: .userInteractive).async {
        let image = self.getPage(name: self.name, at: indexPath.row, compression: 0.35)
        cell.configureCell(image:image)
    }
    return cell
}`

However, sometimes the SDK shows this error:

Error getting page: LibZip error: Zlib error: data error

And if I slide the UICollectionView very fast, it shows this fatal error:

Assertion failed: Failed to read 864937 bytes. Got 564606 instead.: file SwiftZip/ZipEntry+Utils.swift, line 37

Could anyone, please, give me any hint on why is this happening?

Thank you very much.

Best regards

For example: save method from ZipEntry extension is inaccessible

let zip = try? ZipArchive(url: fileURL)
_ = try? zip.entries().first?.save(to: unzipedFileURL)

Hi,

First of all, great project. I think a solid Swift wrapper around libzip is just what the Swift community needs.

I'm having some problems with 0.0.3. I see you replaced libzip's built-in encoding guessing with a Foundation based one. I'm sure there are good reasons, but for my purposes this is much too slow. It causes a ~600% slowdown of my code in comparison to 0.0.2, to the point where ~85% of the total time searching for and extracting a file is spent on encoding guessing (very large zip file).

I think it would be a good idea to expose the built-in strategy from Swift, preferably by default. Maybe decodingStrategy could be an enum with an additional case for Foundation based guessing.

my code:

for entry in archive.entries(version: .current) {
        // Get basic entry information
        let name = try entry.getName()
        let size = try entry.stat().size
        print("\(name) -> \(size as Any)")

        // Read entry contents into a `Data` instance
        let data = try entry.data()
        print(data)
    }

results:

➜  MyAppSwift swift run MyAppSwift
[2/2] Merging module MyAppSwift
document.json -> Optional(627)
627 bytes
pages/DD2372FD-EEFA-4F85-BDBD-D24EF3C1E124.json -> Optional(22888)
22888 bytes

this should return the contents of the file not the file size or am I doing something wrong here?

I am trying to programmatically make an ePub file. To do this I need to have an uncompressed "mimetype" file contained in the zip. Can I use SwiftZip and mark one file as not to be compressed or simply create the zip file with no compression for any files? I can't see anywhere in the documentation for how this would be done.
