Usage

In general WaterfallGrid or LazyWaterfallGrid APIs are very similar to other SwiftUI views like LazyVGrid and ForEach; both views have same initializers, allowing to easily switch between eager and lazy version.

WaterfallGrid(
	items: .columns([.init(), .init(alignment: .trailing, spacing: 10)]),
	spacing: 20,
	data: [0, 1, 2, 3, 4, 5, 6, 8, 9, 10],
	id: \.self
) { item in
	ItemView(item: item)
}

• items can be either rows() or column(), passing an array of WaterfallItems.Row or WaterfallItems.Column to specify how to arrange rows or columns; alignment and spacing allows to customize position and spacing of each view in a column/row
• spacing specify the distance between columns or rows
• data the collection of items to be showed in the grid
• id the keypath to identify which property of each element is the id. For Identifiable elements, this is inferred.
• content: a closure that returns a view for each element of data.
