Common Mistake while using @Published | RunLoop.Main vs DispatchQueue.Main | Combine

A very common mistake that we make while using the published property is missing the Schedulers while subscribing.
Due to this, the subscribers are notified about the change in the value of published property, but we do not get the data.
In this video, I've explained this problem, it's solution and difference between two schedulers i.e RunLoop.Main and DispatchQueue.main.

Hi Pallav, thanks for your videos those are really helping to easily understand the concepts with in a few minutes. Great work. I do have a query that isn't @Published works only with SwiftUI, which was not getting observed with UIKit.

Thank you so much for the amazing short video, it gave me a proper detail to debugging as well

[@barnaliroy3256]

Can you please make one video related to background operations which will cover the topic OperationQueue and GCD. Thanks for all the video. its really helpful for me.

I don't think this is a proper solution to the problem as these schedulers dispatch work asynchronously to some time in the future. The real solution would be to use the parameter emitted by the observer which is omitted by the '_' in line 24. By using the publisher's emitted value we would decouple the view controller more from the view model since the table view data sources methods wouldn't reference the view model anymore. This is even the suggested solution by the guy which is referenced in the video description(avanderlee). It's easy to find the proper solution on his blog. @iCode: Maybe you should be doing a follow up video talking about this.

Exactly

Pallav, why @observedObject is not used as property wrapper for viewModel instance in your example and ViewModel class is not extending to ObservableObject protocol ?

[@pvj89]

Hi Pallav, I have question can you please tell me how optional is implemented in swift? It was interview question.

[@malleshaholeyache4464]

Hi brother. May i ask why are you not posting any videos on your channel since last 5 months? Most of us eagerly waiting for your videos brother. Please do videos on iOS app development. Please guide us with your great knowledge by your astonishing explanation 😊🙂

[@iCode_Happy_Coding]

Thanks for the kind words Mallesha. I’m working on something which is going to be very useful for most of the developers (beginner/intermediate). It’s a series of videos (on same topic) and most of it is done. Will try to release it by end of this month 🙂
