An example project that demonstrates fetching data from the network with Combine and SwiftUI.

A few notess:
- there is no need to spell out every string literal for CodingKeys, only those that differ. E.g. case title, case url, case description = "explanation", case date
- there is no need for the init(from decoder: Decoder). You can omit the properties you do no need and they will be ignored
- there is .decodeIfPresent(…) method useful for optionals.

Can't find the book "App Development with Swift", do you have a link?

Is this a video from 2020? Why did you only upload it now? Just wondering.

I think that publishers should be declared as private(set) var .
