#Brotli An iOS and OSX wrapper for Google's Brotli project.
Simply add the following to your Cartfile:
github "matthewcheok/Brotli"
and then run carthage update
Brotli is both Objective-C and Swift compatible!
Simply import the framework:
import Brotli
To compress use func compressedData() or func compressedDataWithQuality(quality: UInt) where quality ranges from 1 to 11.
To decompress use func decompressedData().
Take a look at the playground (in the included workspace) for a more detailed example.
Below are some rough benchmarks on typical JSON content running on a iPhone 6. A quality of 5 nets you pretty much equivalent or better results compared to Gzip on average. Increasing the quality trades compression time for better compression ratio and decompression time.
