I don't understand. How is this better than using `LAContext` directly?

Indeed. The readme itself says it “aims to be a simple example of Apple's not-so-new LocalAuthentication API usage“. So this is more like a “swifty wrapper” around LAContext[0].

Yeah. I skimmed through the code. Seems unnecessarily. It does wrap it to run in the main thread, which can be useful.

I've found that more often than not, saving a few lines of code in too many places in the codebase can almost introduce a new dialect of the language for the team and newcomers to the team to learn and maintain.

I thank the author for sharing and taking the time and effort to do this and it seems like others are finding it useful, so it's all good.

Thank you so much for your feedback. I was unsure how to properly name this, but maybe Biometrics Wrapper would have been better.

Regarding LAContext, the only difference is that aiDee adds an extra layer of abstraction with a clean and simple public API (e.g. biometricAuth.authenticateUser(...) instead of context.evaluatePolicy(...)).

If I had a company where I'd need to implement this in 10 different apps, I think I would do something like aiDee.

I think this is awesome, but any Apple engineers should be trying to obviate the need for stuff like this to exist. At least one can hope!

Thanks for your feedback. One can always hope :)

is there something similar for android?
