NOT work for ZLIB in iOS 9.x #4

I got zlib compressed data from network and invoke data.inflate() to decompress. It works fine in iOS 11 simulator, but fails in iOS 9 simulator. The function _compression_streamprocess in DataCompression.swift always return -1. Neither zlib level-5 nor level-10 can be decompressed Same data can be decompressed by SWCompression in iOS9, so I think it's a bug in this library.

XCode Version 9.1 (9B55) iOS 9.x simulator

Hi. Thanks for your feedback.

Can you try .unzip() just in case. If that doesn't do the trick can you provide some test data or just post the first ~12 bytes of your compressed stream here? (hex encoded)
