I don't think this is true... Apps below iOS 13 won't be able to use the new system-defined UIColors, yes, and users below iOS 13 can't change to the dark-mode using a switch in the Control Center, yes.

But you've been able to change the "user interface style" for view controllers since iOS 12 [0]. And you've been able to add UIColors to asset catalogs that change depending on that setting since iOS 12 as well.

I'll be honest, I haven't tried this myself. But either this works or Apple's documentation is wrong.

I sure hope you're right! It would seem pretty crazy to be forced to choose between iOS 12-and-below and Dark Mode. Thanks for the pointer!

Depending on the target user for your app, you may see 90%+ on iOS 13 soon, anyway.
