ChessEngine framework is inspired by the open sourced project Stockfish for iOS, it’s source code can be downloaded from here. I found this project has not been updated for a long time and it’s internal engine is stockfish 6, while the latest version is stockfish 8. So I decided to create an iOS framework that uses stockfish 8.

Thanks.

Stockfish for macOS can be found here stockfish-mac.
