open-source-ios-apps VS HSTracker

Then it's easier. There is a community list that took 5s to find and there seems to be nothing in there that fits your description.

There’s this repo but the hard part is you have to search through this to find one that’s active

Not an ios guy.But why don't you give Beam a look or one of the reddit clients mentioned here ( just do a 'find in page' ->search for reddit )

There’s a giant list here on GitHub

This repo has a huge list of open source projects: https://github.com/dkhamsing/open-source-ios-apps

Yes: https://github.com/dkhamsing/open-source-ios-apps

I think HSReplay has something for Mac: https://github.com/HearthSim/HSTracker

Something like HSTracker grabs control of the process and fiddles with its memory directly (at least I'm pretty sure that's how it works), and it's open-source on GitHub (https://github.com/HearthSim/HSTracker), so maybe that could be a good starting point. I know that can read what's happening, but I don't know if you'd be able to play cards the same way --- it would definetly be worth looking into. At the very least, you need something like that for accurately reading the game state, as I feel dealing with screen captures (which is the only viable alternative) would be extremely painful.
