> At least with obj-c these errors will only pop up at runtime

But it's not a good thing. There's still an error, you're just increasing the chance to miss it.

No I wanted to imply that I actually don’t know how rust handles this case. I think runtime errors are the worst especially with UI. Even when you have a full integration e2e test suite. I take compile errors over runtime errors any day.
