I do data compresssion with libcompression.tbd, which was introduced
in iOS 9.0. There appeared libParallelCompression.tbd in iOS 11.0. But I can't find any information about it, and library header looks like that:

symbols:         [ _BXDiff5, _BXPatch5, _BXPatch5InPlace, _BXPatchFile, _CachePatch, 
                       _DirectoryDiff, _DirectoryPatch, _ISparseArchiveStreamCreate, 
                       _ISparseArchiveStreamDestroy, _ISparseArchiveStreamRead, _PCompressFilter, 
                       _PackagePatch, _ParallelArchiveExtract, _ParallelArchiveGenerateBOM, 
                       _ParallelArchiveGenerateMSUBOM 
...

I have strong suspicion that libParallelCompression is for audio processing.

How to detect the purpose of libParallelCompression.tbd?
Do you know compression libs for iOS, faster that libcompression.tbd?
