Section 3: Method to Load Data
Purpose: Show how to load JSON
This section is pretty cut and dry and I look forward to what the rest of the application looks like. I like the fact that the tutorial shows how to load test data during development.
Section 4: Saving Data
Purpose: This is where the user’s data gets stored from one run to the next.
This is my first time seeing a do-catch statement. I other languages, I’ve seen it as a try-catch and it doesn’t have a specific line on which we are trying.
do {
let outfile = Self.fileURL
try data.write(to: outfile)
} catch {
fatalError("Can't write to file")
}
Section 5: Save and Load
Purpose: Put the finishing touches on the application.
Other than the part where I put “ObservableObject” instead of “ObservedObject”, I think this was a pretty nice tutorial.
