What do I want to do?
I want to create an app that uses python code to process things in the backend, why? since I know python and it has so many useful library's that can save me a lot of dev time.
Another criteria is that the app should be completely offline and therefore the option of a server side process isn't an option
My focus is on IOS for now but it would be cool if I had the ability to go to android as well, so the first thing I've considered is basically creating a native swift app and having my python code translated to C then use that in some kind of ObjC file and then implementing that in my swift codebase... but again like I said this option although not that hard to implement, I would have to write my app twice if I want to have an android app in the future.
Ionic seems like a good option (and correct me if I am wrong) since it uses web techs and deploys some sort of mini server on the client side to host the back end, and I do have some web background... but a lot of people report slow speeds and I plan to manipulate sound in a few instances which I think is gonna be very processer intensive
flutter seems to can't have a direct connection to python or C... or maybe it has but I don't know it, but I have some experience in it
reactNative uses JS, and I have absolutely no idea how to even approach using python in my JS code base
Xamrain is dead
Unity and Unreal engine seem like good options although they seem to bring with them alot of un-needed game related stuff... but maybe I could somehow remove the things that I don't need without breaking the engine
