This is brilliant. Thank you for providing such a detailed overview of MVVM, providing an example and simplifying it all to make it really easy to understand. I have been looking for something just like this! Another video very similar to this showing people how to do exactly the same process, but with Firebase: FireStore read/write etc. instead of local data would also be a great addition in my opinion. There really isn't any videos that i've managed to find that break firebase down into a simplistic app...I think people would benefit greatly from it. Thanks again.

But, you have explained all of the critical information about MVVM, Property Wrappers, SwiftUI etc. You are a really incredible teacher. If you speak a little slower than normal it would be perfect for people whose doesn't native language is English. I watched with 0.75 :) I became your huge fan!

This video is by far the best I could find to finally understand MVVM and property wrappers. Thanks a lot. I have small side question regarding the Test project: when you added the ZStack, the background of the app became gray. I couldn't figure out how to make it back to white. Why did it became gray and how to change it?

@AMchou
@AMchou 3 жыл бұрын
Hi, Thanks a lot for the info, it was very helpful. When you create the Navigation Link for the name, if you wanted to have a more detailed view and perhaps edit details of "name" would it be necessary to create an entirely new view or could we incorporate a func in the VM to do so?

Thank you. You explained it very well! Where should I create other view models? For example, I want to create another view model for editing items, so the model will represent a single item. Should I create an instance of that view model inside the main view model, or in the view itself or something else?

This is indeed a fantastic tutorial. Even as a beginner, I understand most, thank you! One question if you (or others) don't mind. You have talked about how a ViewModel interacts with a View. But what do you do, if you have two ViewModels and want them to interact? I have tried in ViewModel A to add ViewModel B as an @StateObject (get an error: ) weird
@asseeger
@asseeger 3 жыл бұрын
That's a good question that I have asked myself as well-I guess what it comes down to is to find a spot in your application where you have access to both of the view models (most likely the spot where they are created), passing down a reference to the respective other view model. Those could be optional properties, I guess.

Thank you for this video. Where do you manage @FetchRequest with CoreData? IMO it should go in the ViewModel. Or do you use it in the View directly?
@SwiftyPlace
@SwiftyPlace 3 жыл бұрын
It would be great if we could use @FetchRequest in a view model. This will not work because it needs the NSManagedContext that has to be added in the environment with .environment\.managedObjectContext, context) Core Data with MVVM is a bit more tricky. I explain more about it in this Core Data specific tutorial kzfaq.info/get/bejne/bJmfrKZmx7vZmpc.html

Awesome content, thanks a lot! What is your solution to handing down instances to the detail view from a list to let the user make changes (like e.g. changing the todo's title-as your are handing down an unmutable instance from within the closure, you do not have a binding... Right now, I create a binding myself in the detail view by finding the instance via it's `id` in the view models array, but I do wonder if there is a better way to do this...
@SwiftyPlace
@SwiftyPlace 3 жыл бұрын
I think changing the item in the item array by id, is a feasible approach. Not sure if there is a different way because your data always is represented by this data array and that is the one that needs to be changed. For the title I would have an extra @Published property in the view model. In order to let the user change it, I would show an extra editor view with a textfield. The view gets access to the view model with @ObservableObject or directly to the view models property with @Binding.
