Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding WaterfallGrid as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
  .package(url: "", from: "0.3.0")


You can install WaterfallGrid via CocoaPods by adding the following line to your Podfile:

pod 'WaterfallGrid', '~> 0.3.0'

Run the pod install command to download the library and integrate it into your Xcode project.



You can create a grid that displays the elements of collection by passing your collection of data and a closure that provides a view for each element in the collection. The grid transforms each element in the collection into a child view by using the supplied closure.

WaterfallGrid works with identifiable data (like SwiftUI.List). You can make your data identifiable in one of two ways: by passing along with your data a key path to a property that uniquely identifies each element, or by making your data type conform to the Identifiable protocol.

Example 1

A grid of views of type Image from a collection of data identified by a key path.

WaterfallGrid((0..<10), id: \.self) { index in
    .aspectRatio(contentMode: .fit)

Example 2

A grid of views of type RectangleView from a collection of Identifiable data.

WaterfallGrid(rectangles) { rectangle in
  RectangleView(rectangle: rectangle)

or, for simple cases like this, just:

WaterfallGrid(rectangles, content: RectangleView.init)

Grid Style

To customise the appearance of the grid call the gridStyle function and pass the parameters you want to customise.


WaterfallGrid(cards) { card in
  CardView(card: card)
.gridStyle(columns: 2)
WaterfallGrid(cards, content: CardView.init)
  columnsInPortrait: 2,
  columnsInLandscape: 3

Scroll direction

WaterfallGrid(rectangles, content: RectangleView.init)
  scrollDirection: .horizontal

Spacing and Padding

WaterfallGrid(rectangles, content: RectangleView.init)
  spacing: 8,
  padding: EdgeInsets(top: 16, leading: 8, bottom: 16, trailing: 8)


WaterfallGrid(rectangles, content: RectangleView.init)
  animation: .easeInOut(duration: 0.5)
