How to zip, unzip files in Objective-C (arm64 support)

Question

I am looking for a way to zip and unzip files on iOS with arm64 support. Is there already a ready-to-use way for zip and unzipping files with arm64 support? (Best if there is also a way to integrate 7zip, bzip2, gzip, rar)

I am using SSZipArchive now, but it isn't working:

#import "SSZipArchive.h"

NSArray *nameWithoutExtention = [[[[self files] objectAtIndex:indexPath.row] lastPathComponent] componentsSeparatedByString:@"."];
NSString *fileName = [nameWithoutExtention objectAtIndex:0];
NSString *destPath = [NSString stringWithFormat:@"%@/%@", self.directory, fileName];
[fileManager createDirectoryAtPath:destPath withIntermediateDirectories:YES attributes:nil error:nil];
[SSZipArchive unzipFileAtPath:[[self files] objectAtIndex:indexPath.row] toDestination:destPath];

You can look at the official SSZipArchive Objective-C example (works on iOS11 which is pure arm64).

To zip:

NSString *sampleDataPath = [[NSBundle mainBundle].bundleURL
                            URLByAppendingPathComponent:@"Sample Data"
                            isDirectory:YES].path;
NSString *zipPath = [self tempZipPath];
BOOL success = [SSZipArchive createZipFileAtPath:zipPath
                         withContentsOfDirectory:sampleDataPath];

To unzip:

NSString *unzipPath = [self tempUnzipPath];
BOOL success = [SSZipArchive unzipFileAtPath:zipPath
                               toDestination:unzipPath];

Where tempZipPath and tempUnzipPath were declared as:

- (NSString *)tempZipPath {
  NSString *path = [NSString stringWithFormat:@"%@/\%@.zip",
                    NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0],
                    [NSUUID UUID].UUIDString];
  return path;
}

- (NSString *)tempUnzipPath {
  NSString *path = [NSString stringWithFormat:@"%@/\%@",
                    NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0],
                    [NSUUID UUID].UUIDString];
  NSURL *url = [NSURL fileURLWithPath:path];
  NSError *error = nil;
  [[NSFileManager defaultManager] createDirectoryAtURL:url
                           withIntermediateDirectories:YES
                                            attributes:nil
                                                 error:&error];
  if (error) {
    return nil;
  }
  return url.path;
}
