# addItem(_:)

Adds a dynamic item to the dynamic item behavior’s item array.

## Declaration

```swift
func addItem(_ item: any UIDynamicItem)
```

## Parameters

- `item`: The dynamic item to add to the item array.

## Discussion

Discussion You can add a dynamic item to one or more dynamic item behaviors. For example, you could add a dynamic item to one dynamic item behavior to configure the item’s elasticity and to a second dynamic item behavior to configure its density. This is especially useful when you are defining custom, combined behaviors for your dynamic items.
