What Is an indexPath in Swift?

A developer provides a quick tutorial on working with the indexPath in Swift, and explains what this bit of code is used for when creating applications.

In Swift, an indexPath is a list of indexes that, together, represent the path to a specific location in a tree of nested arrays.

It describes an item’s position inside a table view or collection view, storing both its section and its position inside that section.

Each index in an index path represents the index in an array of children from one node in the tree to another, deeper, node.

NSIndexPath has a read-only structure that contains two Int property sections and rows if you're working with UITableViews or a section and item if you're working with UICollectionViews.

You create them with the NSIndexPath:forRow:inSection: factory method:
Swift
1

let indexPath = NSIndexPath(forRow: 1, inSection: 0)

And read them by accessing their properties:
Swift

1

print("row is (indexPath.row)")

It's as easy as that!
