[Discussion] Implementing custom alignment guide like SwiftUI

[muukii]

I'm wondering how I do implement an advanced layout specification that's like SwiftUI's custom alignment guide. https://www.hackingwithswift.com/books/ios-swiftui/how-to-create-a-custom-alignment-guide

In the Flexbox layout, we can't align the elements over the stacks. but SwiftUI was able to make it available.

Does anybody have ideas?
