So Swift does implicit conversions?

  Not generally, no. Optional is a special case. It's the only special case I'm aware of - though possibly some of the things they added for SwiftUI might also do this? Like `Binding`? I could be wrong. Point is, it's not a feature available for developers to use with their own types. Edit: 'Binding' uses the PropertyWrapper attribute, which is similar in that it allows treating a wrapper type like the type it wraps. This is a language feature that is available to users. I'd be interested to know if Optional is the only "magical" type.
