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
- In Xcode, select File > Swift Packages > Add Package Dependency.
- Enter
https://github.com/thaisrfernandes/PinterestLikeGrid.git
- 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)")
}
}
}
}

}

...
}

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.
