// Nested support and collections left as an exercise for the reader.

// This takes some inspiration from https://gist.github.com/chriseidhof/3c6ea3fb2102052d1898d8ea27fbee07
// but uses a different approach.
// Instead of trying to calculate the position of each item and placing them manually using calculated coordinates,
// this calculates the amount of space each item wants to take up, then splits the items into rows that should fit
// within the available width.
// Then, the views are distributed into rows, made up of an HStack for each row inside a VStack.
//
// This seems non-conventional, but I was having trouble getting the frame of my top-level view to be respected when returning

import UIKit

/// A scroll view that allows scrolling using a hardware keyboard like `NSScrollView`.
/// Supports arrow keys, option + arrow keys, command + arrow keys, space bar, page up, page down, home and end.
/// Limitations:
/// - Paging scroll views (isPagingEnabled = true) are not supported yet.
/// - The scroll view must become its own delegate so setting the delegate is not supported yet.

If you work on a Swift project that follows the Model-View-ViewModel (MVVM) architecture or similar, you may want to jump to counterpart in Xcode from your view to your model, and then to your view model. (ie. by using Ctrl+Cmd+Up and Ctrl+Cmd+Down).

You can do this in recent versions of Xcode by setting a configuration default.

From a terminal, just type this command and press Enter:

defaults write com.apple.dt.Xcode IDEAdditionalCounterpartSuffixes -array-add "ViewModel" "View"
