SwiftUI - Intro to MVVM | Example Refactor | Model View ViewModel

In today's video I give you an introduction to the concept of the Model View ViewModel (MVVM) Architecture with SwiftUI. We will refactor a screen into a viewModel as an example. I explain the concept for those who have no idea what MVVM is so I keep it pretty basic. The general idea is to keep your business logic out of your views.This tutorial was created in Xcode 12.5 and Swift 5.4.

I’ve heard several explanations of MVVM, but thinking of the view as being dumb makes perfect sense to me - I finally get it!

[GrégoryV-bs]

I don't know if you're the best teacher of the world, but your presentations and explanations are so clear that I've enrolled your free lessons for now, and it's so transparent that the way you are teaching is the best way for me to learn. It's complete, it's evolutive... You are my SwiftUI hero now! Many thanks to share your firsts lessons, it's showing how the way you teach is efficient. Please keep the way going on. I'm wishing the best for you! Best regards. Greg

This is easily the most helpful video I have seen to explain SWIFTUI MVVM

[CodeDropAccount]

A great video Sean. Thank you for the real-world code example during the explanation. I would very much enjoy seeing more of your architectural explanations.

Who knew I was passively making a MVVM.

[callmetyler]

Something always felt wrong about putting functions in my view structs 😅 Thanks for this clear explanation! :)

[Poroto]

Would this refactor have been the same if we wanted to go with MVC rather than MVVM? I kinda struggle to find the difference between the two tbh.

[hengideguru]

This is clean stuff @sean. I can hardly find content that is so clean in iOS. Thanks a lot, please come up with a big how to build video with MVVM pattern. Much love ❤️

[lukasbro]

That's exactly what I need, thank you, your videos are always great!

new bee in iOS, but quickly pick it up based on your videos, thanks a lot, no 1 iOS training online

[coolisfoolable]

You've helped me getting that darn @published / @observableobjec concept to sink in. Thanks!

[Bjorn-EricAbrahamsson]

Great video! Really appreciate the "visual learning" stuff.

[justinpelletier]

Could you do a video breaking down Alerts and how you set it up in this video?

[NishantNarola]

great example for starter atleast..keep it up..one suggestion instead of calling getAppetizers function in onAppear, call in initializer in view model class

[ankitsoni]

Thanks brother, it was simple and super crisp.

[braydoncoyer]

A great example to aid in learning this model. Thanks for sharing!

[sabarahuja]

Curious why the use of @stateobject in the view instead of @observedobject?

[co]

Great video! Is it common to actually put the model in a separate file on its own? So that you have a more lcear 3 part division of the MVVM?

[nadnerb]

How does this compare to the MVC? Model-view-controller? It seems to me that your 'viewmodel' is doing the same thing a controller would in an MVC.

I am still catching up, so I have a lot of gaps in my knowledge and understanding of Swift, SwiftUI, SwiftData, etc. Your videos have been very helpful so far. The pace and focus of your videos are perfect. For this one, though, I am wondering how the advent of SwiftData changes the MVVM. Can you pull SwiftData context model into an Observable class model, or does SwiftData break the MVVM?
