The Complete Guide Using SwiftUI MVVM Async Await & SwiftUI Error Handling: SwiftUI Tutorial

The Complete Guide Using SwiftUI MVVM Async Await & SwiftUI Error Handling: SwiftUI Tutorial

**Warning Fix**

i.e to create an instance of it in the initialiser do the following below

@StateObject var vm: MyViewModel

init() {
self._vm = StateObject(wrappedValue: MyViewModel(service: MyService()))
}

In this complete guide Using SwiftUI MVVM Async Await Example, we will look at the new Swift Concurrency feature Async/Await and SwiftUI Error Handling.

We’ll look at the benefits and how we can use it to improve our asynchronous networking code, we’ll look at the things to look out for when using the new Swift concurrency code and also how we can handle errors. Well, let’s jump into this SwiftUI tutorial to see my swiftui async await project structure.

I can honestly say this is the first video on async/await that really clicked with me - so good. Thanks so much, looking forward to more videos!

[vojtechkalivoda]

This video is actually super great example of Async/Await!!! 🔥🚀Also when u show us how to handle these edge cases with custom errors... It is PARADISE of learning hahaha Thanks a lot mate

[gastongasquet]

Great great video about async await. It's the most complete video that also includes response and error handling. Terrific.

[felixmatusinio]

I think this might be the best practices for mvvm async/await in swiftui. I must subscribed!

[Collins]

Best ever swift networking tutorial I've seen on YouTube. Thanks man.

Feels like using Flutter and Riverpod Mvvm pattern 💙

[StewartLynch]

Another extremely useful and planned out video. Love it.

[iLoveAppl]

good stuff my bro people are charging money for this in deprh content we appreciate you my bro

[DougRobison]

I enjoyed this video. Thank you for putting it together. It's nice to see async/await finally make it to Swift to things can be simplified

[douglasalexander]

Thanks a bunch. You do a great job clearly explaining the material.

[JoeVargas]

Thank you for this! Very well explained! You have got yourself a new subscriber!

[jimkurring]

Thank you for your continued stellar SwiftUI content. Great scope covered and explanations.

[jontaylor]

Thanks. I’m digging into swift right now and I’m kind of surprised that it is only just now getting async await support. I guess my timing is good.

[KhanhQuang-ffve]

I love you video mvvm with asyn ❤, you are wonderful

[paulallies]

Informative, good code structure, and nicely explained. Thank you very much.

[ChrisKobrzak]

Thank you so much for putting effort into making all these videos on iOS development, Tunde 🙇‍
I'm relatively new to Swift and I've already learnt a lot! I really like your focus on practical examples, explaining your decisions as you go, solid naming conventions and unit testing.

Just a small suggestion - you might want to consider recording the screen in a lower resolution to make the videos a bit more smaller screen-friendly. I know a phone is perhaps not the best tool for watching YouTube and it's great you've increased the font size in Xcode but I think scaling the resolution a bit would make your content that tiny bit more accessible.

[timsonner]

So cool, so much fun. great techniques and explanations. I would love to see how you would implement infinite scrolling in the list, the API returns only first 20 results (671 characters, so not truly infinite). Maybe throw in the searchable modifier and build out the UI a bit. Just thoughts. I'll figure it out, Tanks tunds! Great choice of API. Hyped!

[erdemsenol]

Nicely explained, thanks. Can you do an in depth tutorial with Mapkit/CoreLocation? SwiftUI 3 seems to have some features to implement it easier.

[syedmeer]

Which one is more better approach Asyn/Await or Combine ?
please who see this comment must reply your reply is really helpful for me.

[zeeshansuleman]

Create some more videos on unit tests and dependency injection

[jontaylor]

On larger projects do you typically use a DI library or container or do you still manually create services and pass them through constructors?
