Is there a practical way to compress NSData?

Question

I haven\'t seen any documentation on the topic, but that doesn\'t mean it doesn\'t exist.

Answer 1

In iOS 13 and macOS 10.15 or newer you can use the new compressed method of NSData:

let compressedData = try? NSData(data: data).compressed(using: .zlib)

Unfortunately this method hasn't been ported to Swift's native Data class, but NSData can be simply casted to Data by adding as Data after the above code line.
