I'm just now getting started with combine and reactive programming. This is a great way to get my feet wet. Thanks.

I don’t even use UIKit and I understood it clearly. Awesome tutorial.

Thanks for the very useful explanation. I've watched the video a few months ago and didn't understand the advantages of Combine. But now everything makes perfectly sense!

I have never put nutmeg into mashed potatoes. I will try it next time.

you making such a great video can you make it more for combine framework.

Have problems following your code
Referencing instance method 'sink(receiveValue:)' on 'Publisher' requires the types 'Publishers.Filter<PassthroughSubject<Int, WeatherError>>.Failure' (aka 'WeatherError') and 'Never' be equivalent

Super decent tutorial with plenty of graphics.

Hi Brain Advent great video on combine framework where even apple docs are cumbersome about combine but you explained clearly about the necessity of framework. Can you do more videos on combine that includes debounce clasess.

[rogerpinto]

Super simple explanation! Really nice tutorial 👏

Update for the sink modifier:
add receive completion parameter if compiler is showing error ---> "Referencing instance method 'sink(receiveValue:)' on 'Publisher' requires the types" 👌🏾

.sink(receiveCompletion: { _ in print("process complete") }, receiveValue: { value in
print("A summer day of \(value) Celcius")
})

Lemme ask maybe a kinda odd question. Why would you do this? When you could simply do sendButton.isEnabled.toggle() in the IBAction of the switch. I understand your demonstrating Combine. I get that. And maybe that is the answer, but. Beyond that, and making this a bit more real. What is the benefit of it in this case. Over doing just the one line of toggle?

[waseemasif]

very good video.I guess tutorials should be that simple and concise as you have used UIKit for your demo.Create other videos with UIKit as most of developers not switched to SwiftUI

[setoelkahfi]

Can you please add space after the variable name?

[jasondhindsa]

Excellent example! A bit confusing though! I thought Subscribers had to be reference types.

[developerdiaries]

Nice, but this is something we could have done with a property observer and Notification Center observer. Is it just because the task demonstrated here was too simple to warrant the Combine framework, or is there more to it than just this?

Thanks Brian, where can I get source code?
