I've written and recently open-sourced a full 65C02 simulator core written entirely in Swift. It passes the Klaus functional tests, extended opcode tests, and the Bruce Clark decimal tests. If you want to contribute or are just curious, you can find the project on github:

Well done - and thanks for sharing!

Happy to contribute back I am hoping to have an interesting simulator for macOS and iPadOS sometime in the near-ish future built on this core so stay tuned.
