Usage

SwiftCompression is a Data extension. It lets you easily compress/decompress Data objects this way:

// Create NSData from file
let path = URL(fileURLWithPath: Bundle.main.path(forResource: "lorem", ofType: "txt")!)
let loremData = try? Data(contentsOf: path)

// Compress and then decompress it!
let compressedData = try? loremData?.compress()
let decompressedData = try? compressedData?.decompress()

// You can also choose one of four algorithms and set a buffer size if you want.
// Available algorithms are LZFSE, LZMA, ZLIB and LZ4.
// Compression without parameters uses LZFSE algorithm. Default buffer size is 4096 bytes.
let compressWithLZ4 = try? loremData?.compress(algorithm: .lz4)
let compressWithLZMAReallyBigBuffer = try? loremData?.compress(algorithm: .lzma, bufferSize: 65_536)
