PinterestLikeGrid

An easy way to create beautiful grid views on SwiftUI :)

This component allows you to split an array into any number of columns while still handling the original array with the correct indexes.

Installation

Swift Package Manager

1. In Xcode, select File > Swift Packages > Add Package Dependency.
2. Enter https://github.com/thaisrfernandes/PinterestLikeGrid.git
3. Follow the prompts to select the version or branch to use.

Usage

The component requires an array of hashable items to be displayed, the number of columns to be used, and a closure to represent each item in the grid.

Here's an example of how to use it:

struct ContentView: View {
    @State var data = [1, 2, 3, 4]
    
    var body: some View {
        PinterestLikeGrid($data, columns: 3, spacing: 8) { item, index in
            Text("\(item)")

            if let index = index {
                Text("Index: \(index)")
            }
        }
    }
}

Parameters

Parameter	Type	Description
data	Binding<Array<T>>	Binding array of hashable items to be displayed on the grid
columns	Int	(Optional) Number of columns to display grid. The default is 2.
columnSpacing	CGFloat	(Optional) Number of spacing between columns. The default is 8.
rowSpacing	CGFloat	(Optional) Number of spacing between rows. The default is 8.
spacing	CGFloat	(Optional) Number of spacing between rows and columns. The default is 8.
content	(_ item: T, _ index: Int) -> View	Closure that receives an item and an index that must return a view to represent each item in the grid

Basic Init

PinterestLikeGrid($data) { item, index in
    ...
}

Number of Columns

PinterestLikeGrid($data, columns: 3) { item, index in
    ...
}

Items Spacing

PinterestLikeGrid($data, spacing: 12) { item, index in
    ...
}

Items Vertical Spacing

PinterestLikeGrid($data, columns: 3, rowSpacing: 6) { item, index in
    ...
}

Items Horizontal Spacing

PinterestLikeGrid($data, columnSpacing: 3) { item, index in
    ...
}

Implementation details

PinterestLikeGrid uses a helper method called splitData to split the data array into the specified number of columns. The method returns an array of arrays of hashable items.

Then, it uses a HStack to display the columns and a VStack to display the items in each column.

getIndexInList(for:) is a helper method that returns the index of a specified item from the data array.
