Hi, very good tutorial !, I have an issue, I call it from other view(main menu) but I can´t pass a parameter like questionaryId to Quizmanager, how I can do that?

[@FabricioMTL]

I have a question if I want to build an quiz in superBase with a configuration of different user type app cause I don’t want to hard code The question everytime I juste want the question to be push when I upload them do you have an tuto for different user type like : admin , user for example ?

Que tal Jason, he seguido los pasos para recrear tu proyecto, pero me encuentro atorado en la linea let data = response.underlyingResponse.data, por algun motivo no puedo hacer que se conecte a la base de datos, segun es por el error "Value of type 'PostgrestResponse' has no member 'underlyingResponse' soy novato en el uso del codigo, y no se como resolverlo.

Dude, the content is A+ but the edit is a bit hard to follow At 9:00 it suddenly jumps to having added the value to the View for the preview, which took me a few re-runs to notice the difference. At 17:47 you change this to QuestionView(question: .con......) and don't show what that text is supposed to be, which breaks the preview of it. For anyone else... you need: ``` #Preview { QuestionView(question: .constant(Question(title: "In which year was the iPhone introduced?", answer: "2007", options: ["2006", "2007", "2008", "2009", "2010"]))) } ```

Thanks for watching! Yeah sorry about that, my older videos were edited using a python script lol so thats kind of why it may appear jumpy

[@marwaawad3677]

thank youu!!!

let data = response.underlyingResponse.data is throwing Ann error it is not working for me I followed the entire tutorial line by line it does not work

[@jasondubon]

Try just response.data

From minute 16 - 20 had some audio issues but audio is fine afterwards

I cant add supabase-swift i get error supabase-swift could not be resolved

[@jasondubon]

restart xcode or remove and add the packages again review your packages in the project section to make sure supabase is added

I’m getting an issue. “Unable to fetch data” in the console

[@jasondubon]

@@rparham1997 is that the error that supabase returns ?

[@jasondubon]

@@rparham1997 what is the model you are using to decode the data ?

[@jasondubon]

@@rparham1997 Although it looks like it might be an access thing with the setup of Supabase

[@DannyBoy443]

Why do people feel the need to show themselves on their tutorial videos? lol. We need to stop doing that.

[@Travis_Chow]

Hi Jason! Love this tutorial. However, I got hard stuck on one line of code. 28:01 see if you could help take a look 🥲 let data = response.underlyingResponse.data the "underlyingResponse.data" didn't bold like yours did, and it says "Value of type 'PostgrestResponse' has no member 'underlyingResponse'"

[@jasondubon]

what other options did it show ? also make sure you have .execute() at the end

[@Travis_Chow]

@@jasondubon Thanks for the reply 💪 I do have the .execute() at the end. And here's the whole chunk of code. init(){ Task{ do{ let response = try await client.database.from("quiz").select().execute() let data = response.underlyingResponse.data let decoder = JSONDecoder() decoder.keyDecodingStrategy = .convertFromSnakeCase let questions = try decoder.decode([Question].self, from: data) await MainActor.run( self.questions = questions) } catch { print("Error fetching questions") } } } when i type .execute() in the previous line, I pick the option with "async throw ProgrestResponses " However, it says async "execute(options:)" used in a context that does not support concurrency.

[@jasondubon]

@@Travis_Chow supabase had some updates so can you try this let questions: [Question] = try await client.database.from("quiz").select().execute().value

[@jasondubon]

And you have to update the Question model with the coding keys (this gets rid of the need of coverting from snake case) struct Question: Identifiable, Decodable { let id: Int let createdAt: String let title: String let answer: String let options: [String] var selection: String? enum CodingKeys: String, CodingKey { case id case createdAt = "created_at" case title case answer case options case selection } }

I have a video dropping soon that should dive into these changes
