iOS SwiftUI Questions

[robbieduncan]

I have just released my first Swift UI App (thread). This is entirely SwiftUI (no uses of UIViewControllerRepresentable). If anyone wants to ask me how I did anything in the app please ask questions and I'll try and answer...

Hehe, I clicked on this thread thinking "I think I know my way around SwiftUI well enough to answer whatever question is in here" - Was greeted by an offer to get my own question answered - Congrats on the app

Hopefully we will get some questions we can answer between us

SwiftUI is really pretty simple right up to the point where it becomes really hard/something plain does not work

Let me pose a question then (for my next app I am working on).

If you have a hierarchical list have you found any way to enable drag/drop to re-arrange items? This is possible in normal lists using ForEach with the relevant modifiers on the ForEach but hierarchical lists don't use ForEach and List does not support onInsert (for example)

Hm. Interesting question - It's not really something I've had to deal with so I haven't thought much about it. I can't really off the top of my head think of any way to make that work with the List view. Seems like it ought to be possible but it doesn't seem like there's an easy way around it right now - without having looked much into it

I was wondering if there was something I have missed as I can't see any way round it either beyond basically re-implementing the functionality using ForEach and DisclosureGroup. Which I may end up doing but really don't fancy as getting the insertion position correct means messing with coordinate spaces which is normally pain!
