Getting Started With Combine

Maybe you’re not yet ready to jump into SwiftUI but that doesn’t stop you from getting started with Combine if you can require iOS 13.

Overriding Dark Mode

Here’s my situation. I had a pre-iOS 13 App that already had a setting to allow the user to switch from the default appearance to a “dark” mode. When updating to iOS 13 I wanted to keep the “light” and “dark” modes but also have the choice to follow the device appearance setting:
