Ehh ridiculously easy seems like a stretch. You need to adapt all of your designs for dark mode and if you haven’t thought about it in the past or you don’t have a design system that is easily adaptable in the app you are going to be updating a lot of components and screens.

OK, yeah, you need to think about it first, but it should just be a case that all the colours in your design have alternates. It's mostly a case of differentiating between background and foreground colours. Then you put all your colours in the Assets, only ever used named colours, maybe hardcode some shortcuts, then you never think about it again.

There are a couple of rare cases here and there, eg custom drawing using Core Graphics, where using cgColor won't pick up the change, you have to grab the underlying colour again and force a redraw
