XCode12 has changed a little bit since this. There is no single view template and checking Core Data when creating a new project seems to inject a lot of code in by default that is not shown here. Unsure how much it will impact this tutorial.

I wish there was more detail on when a change of a binding triggers a redraw. I noticed it depends on where and how it’s created. On a @State var with $ it triggers on change. If you creat it with get / set it still triggers, basically every time it is recreated so on any state var change and if it’s created it triggers never. I wish a tutorial would go into detail on how to handle those triggers.

Hey paul, as you talk through whats happening could you highlight the code or mouse over it, like during 3:58
Great video one again though.

Do you have ideas for how to use enums with toggles?
