GzipSwift is a framework with an extension of Data written in Swift. It enables compress/decompress gzip using zlib.
GzipSwift requires no privacy manifests since it does not access to any privacy information.
import Gzip
// gzip
let compressedData: Data = try data.gzipped()
let optimizedData: Data = try data.gzipped(level: .bestCompression)
// gunzip
let decompressedData: Data
if data.isGzipped {
decompressedData = try data.gunzipped()
} else {
decompressedData = data
