Feature: SwiftUI text-based snapshot testing

[rjchatfield]

I would very much prefer a text based "recursiveDescription" of SwiftUI hierarchy. Even if I pull all my business logic out into a Store/Reducer/State, I still have branch logic within the Views.

Personal preference is to exclude frame rects. Just the hierarchy and properties where possible.

I have no suggestion for what this should look like, but here is an issue to track the discussion/progress.

I've also posted on Swift Forums: https://forums.swift.org/t/swiftui-debugdescription/39099

Does this do anything for you?

assertSnapshot(matching: view, as: .dump)

This is also something I'd be interested in, have you tested the approach you are suggesting @darknoon ?

dump doesn't seem to work. I have tried and I only see a description of the store, which takes forever and has a lock and pointer properties that change on every run.

I'm going to convert this to a discussion for further collaboration. We'd definitely be interested in a strategy here! We want to keep issues focussed on bugs, though.
