Instead of:
.map { $0 as? UISwitch }
.ignoreNil()
You can go with:
.filterMap { $0 as? UISwitch }

I think you can take this one step further and put it all in the filterMap
.filterMap { ($0 as? UISwitch)?.on }
I like to minimize the number of operators where possible.

I'll unify it with the filterMap like you suggested. I personally prefer having this kind of separation but makes sense minimize.

Chained *map operators do look a bit cleaner and make sense semantically. However, signal transformations do have a real cost and can add up perf wise so I like to collapse them. In an ideal world there would be a way that happened automatically. But that's a personal pipe dream.

Good point, it's definitely something to consider! And that dream, I hope it becomes reality one day ✨
