# UIToolTipInteraction

An interaction object that makes it possible to show a tooltip when hovering a pointer over a view or control.

## Declaration

```swift
@MainActor class UIToolTipInteraction
```

## Overview

Overview To show a tooltip when the pointer hovers over a view, add a UIToolTipInteraction object to the view. For example, the following code listings shows how to add a tooltip to a label: let label = UILabel() label.text = "Label with a tooltip"

let tooltipInteraction = UIToolTipInteraction(defaultToolTip: "The label's tooltip.") label.addInteraction(tooltipInteraction) If you want your app to determine the tooltip text at a later time — for instance, to reflect the current state of your app — set the interaction’s delegate property to an object that conforms to the UIToolTipInteractionDelegate protocol. To add a tooltip to a control derived from UIControl, use the convenience property toolTip; for example, to add a tooltip to the button: let button = UIButton(configuration: configuration, primaryAction: action) button.toolTip = "Click to buy this item. You'll have a chance to change your mind before confirming your purchase." Setting the toolTip property creates a tooltip interaction for the control, which you can retrieve from the toolTipInteraction property. note: Tooltips appear when your app runs in macOS or visionOS. To show a tooltip in macOS, your app must be an iPhone or iPad app running on a Mac with Apple silicon, or built with Mac Catalyst.
