Get biggest node from an array

Question

I have an array of SCNNodes and I need to identify which one of them has the highest width.

I know how to calculate the width, but not how to compare among all nodes within the array and return the one with the highest value.

Here’s a sample code:

var walls = [SCNNode]()
   
For wall in walls  {
    let wallWidth = (wall.boundingBox.max.x-wall.boundingBox.min.x)
    print(wallWidth)
}

Thanks in advance!

Answer 1

You can use the max function of array.

var walls = [SCNNode]()
let maxNode = walls.max { (left, right) -> Bool in
    let leftWidth = (left.boundingBox.max.x-left.boundingBox.min.x)
    let rightWidth = (right.boundingBox.max.x-right.boundingBox.min.x)
    return leftWidth < rightWidth
}
