Very nice tutorial. Thank you!

I have one question. When returning from the QuestionsView, you manually increased peopleAttended += 1 (27:05) locally instead of re-fetching the updated data. How could I do that? run the asynchronous function fetchData in the onFinish of the QuestionView component and update the view?

Thank you in advance!

i got "The data couldn’t be read because it isn’t in the correct format." when running the code (6:05). Instead of showing the title, i get loading image.

Question: I want to save the quiz results so user can go back and see them afterwards. When I save / load to userdefaults because of the struct tappedAnswer: String = "" it always loses the users answer. How can I save and load the data keeping the users tappedAnswer?

The data couldn’t be read because it isn’t in the correct format.

Thanks for the awesome lesson. In my environment the .data(as: Decodable) option in the Firestore.firestore() object does not exist. I tried using the latest Firebase Version as well as Version 9.6.0 as used in your video. In either version, there is only .data() and .data(with: ServerTimeStampBehaviour). Is .data(as: Decodable) a custom extension?

For everyone who has the same issue as me and wants a fix:
1. Get the data with .data()
let infoData =
2. Manually parse the content of infoData onto the Info Model:
let info = Info(title: infoData?["title"] as? String ?? "", peopleAttended: infoData?["peopleAttended"] as? Int ?? 0, rules: infoData?["rules"] as? [String] ?? [])

Do the exact same thing with the questions Object in the .compactMap{} closure
