What is the best way to present alert with custom view?

[havilog]

I have my own existing Design System.

so I have to present the alert with specific design and want to migrate it to TCA.

but AlertState can't cover my custom views.

so I'm wondering if I could present a custom view, not AlertState, when presenting an alert.

Is it impossible? or Is it being prepared? or shoud I custom AlertState?

Hi @havilog, we have an example of this in our isowords project. There's a custom UI component we have called BottomMenu, and it was first designed in plain, vanilla SwiftUI. This means it's driven off a binding and comes with a custom datatype that describes how to present a bottom menu.

Then we made a TCA friendly interface for the bottom menu where it takes a Store of BottomMenu domain and uses viewStore.binding to derive a binding to hand to the vanilla SwiftUI component.

Does that help?

Hi @mbrandonw, I've checked isoword BottomMenu and it helped me thanks.
but I'm curious that is there any way to adapt nicely using @PresentableState and custom view?

I'm also curious about the above question..
Is there any way to adapt @PresentationState to vanilla SwiftUI component?
I've checked other component like .sheet but I can't use PresentationStore because It was used @_spi annotation

@junyng You are free to @_spi(Presentation) import ComposableArchitecture to access these APIs. They should be relatively stable, but the @_spi will give us a little more freedom to change/evolve them before making them totally public.

@stephencelis
oh, i was wrong.. sorry
According to your description, it's possible to apply PresentationStore for custom components.
I'll try it thanks.
