Incorrect dismiss behavior after presenting UIAlertController UIKit

[nmalevich]

Description

I use AlertState, @presents and present method of UIViewController for showing alerts
I don't have any problems with first show, but after first dismiss property in my state for alerts isn't nil, it is still previous value. So when I try to show next time, it will be nothing, because state isn't change

Hi @nmalevich, you need to make sure to use the ifLet operator to integrate the alert's behavior into your feature:

Reduce { state, action in
  …
}
.ifLet(\.$alert, action: \.alert)

That should fix it.

Since this isn't an issue with the library I am going to convert it to a discussion. Please feel free to continue the conversation over there!
