MVVM + Dependency Injection in Swift | Unit Testing | iOS

Thank you bro.

Out of 25 mins video you explained starting 15 mins on combine and protocol. Content is good but need to concentrate on actual stuff

Superb man...loved your explaination

Hi, it would be great if you create a video on MVVM issues on SwiftUI

Can you please tell us
1. how to identify when to use MVC or MVVM?
2. WhY we use MVVM over MVC?

Thanks.

As few others commented, there is a slight disagreement on the use of VM. The primary purpose of all view patterns are for separating presentation logic away from business logic. So VM as the name suggests should contain only fields and logic specific to a view or set of views. The fields in VM should be subset of actual Model and logic in VM is mainly presentation oriented like formatting a date for the view or responding the change of a field in the view. The core business logic (that could include using network calls to achieve that) and full set of fields should be part of the Model.

Awesome explanation MAN!
BTW, the source code link was expired, could you help to check and update it?

Thanks!

Excellent content, wish we had your videos earlier but nevertheless its a brilliant content.. keep on publishing videos.. Best Wishes !!!

I had a query,
Dependancy Injection - With help of Sw-Inject how it can be used & implemented ? Would love to have a video on the same.
Many Thanks !!!!

this explains very well awesome video and thanks for clearing my concepts about dependency injection and testCases.

Great Video, easy and clean explanation.

Very well explained !! Thanks

awesome one so far!

Thank for the lecture . I download the project but I am not able to run it . can you please explain to run the project ?

nice

Hi Great Tutorial, I have a confusion in UIKit when using MVVM and dependency injection while sending data to DetailViewController. Can you please provide me any code snippet for that. Or share link if you have any tutorial on it. Thanks in advance!

Awesome explanation brother 👏👏. You please keep posting all videos related to Swift iOS . I have great hope that many of us get benefitted from your explanation and questions you ask in every step🙂. We need a gem like you in every learning curves😊

Hi i have a question,can the viewmodel layer be reusable for multiple view layer? Or everytime you create a new view controller you always have to create the new viewmodel even though it have the same use case with the existing viewmodel file

Brief but covered all possible questions. Easy to understand. Great explanation and great work. Thanks for this video.

very good tutorial, thank you for your explanation.

Excellent explanation, without any unnecessary details!

please make a video on solid principles in swift.

Cool tut. Great work brother.

Great video as always. One question I was having is that what's the use case for the model to communicate back to the ViewModel? I understand that View Model is responsible for say making the network call and update the model but didn't come up with a use case where the model changes (without VM's involvement) and needs to communicate back to the VM.

Top-quality contents. Carry on and help us.

Top class explanation of ViewModel and Dependency Injection. I really wonder how did I miss this..

Thanks for the interesting Tutorial. You explian it in a easy and straight way.Keep it up!!. Thank you!

Why I haven’t seen your channel before. Top quality content. Looking forward to learn topics coordinators, architecture, unit tests, rxswift and anything you make :)

Hi Pallav
Thank you for the wonderful videos.

I have one question why did you make the protocol as type of any object? Just to use weak?

If this is the case then how a struct will implement that protocol? and in case if implement then how it can be reference type? 🤯

Great video. Please also make a video explaining the implementation of RIBs architecture aswell. Thanks in Advance.

Thank you for the informative video. Can you please create a video for implementing unit tests for API calls

Your videos r really helpful, thank you 🙏

Pallav with your experience, I think you should make a udemy coarse targeting ios interview.

Really nice video with a lot of good points that other videos on the topic missed. I do have a few issues with it. Calling MV* patterns architecture seems wrong to me. They are patterns designed to solve a specific issue. They are not themself the architecture of the app, seeing them as architecture is what causes people to try to cram all code into one of the letters of the acronym which is not the point with the patterns, it's is also what lead to strange bastard patterns like MVC-N and MVVM-C. MV* patterns are a great tool and they do participate inf the architecture but, they are not THE architecture. Also, you talk like 100% test coverage in itself is a goal, while you should strive for good coverage, the coverage itself is not a way to measure quality as the tests cold be testing absolutely nothing.

Will you make vedio about databuilding in MVVM for us please

As per MVVM view should not be aware about model however when you explained about protocol the closure, it was returning array of flight object to the View in this case view is dependent on model.
I was explaining the exactly what you mentioned in one of the Apple interview however interviewer told me as per MVVM view should not be aware about model.
What is your thought on it?

thanks for this detailed explanation✌️

Well explained, I really liked it the way you explained the MVVM pattern 🔥

Very well Explained. Thank you

Hi bro where should I use presentation logic

May you please keep xcode version compatible with 12.4 (12D4e) in next videos, there is some people still cannot upgrade to latest version of OS/Xcode.

Business logic should be a part of the model.

Thank you for the great, well explained video on MVVM and dependency injection. I am wondering if you can make a video on Apple's device check api.

one of the best videos

I just discovered your channel recently. Nothing more to say, than 11 out of 10. Really top of the line content. I appreciate your effort very much.

This is good but how to test network call?

Combine is a powerful thing, shame Apple not updating it at all.

Hi Pallav, can you make a video on LLD in iOS. It would be a great help :)
