# hoverEffect(in:isEnabled:body:)

Applies a hover effect based on the current phase.

## Declaration

```swift
func hoverEffect(in group: HoverEffectGroup? = nil, isEnabled: Bool = true, body: @escaping (EmptyHoverEffectContent, Bool, GeometryProxy) -> some HoverEffectContent) -> some CustomHoverEffect

```

## Parameters

- `group`: An optional doc://com.apple.SwiftUI/documentation/SwiftUI/HoverEffectGroup to add this effect to.
- `isEnabled`: Whether the effect is enabled or not. If false, the effect’s inactive state will be applied, and it will not apply the active state when hovered.
- `body`: The closure that constructs a HoverEffectContent for each of the effect’s phases.

## Return Value

Return Value A new effect that changes a view’s appearance when hovered.

## Discussion

Discussion You use this modifier to describe how a view should change when hovered. The given closure is provided an empty effect that you use to compose an effect, as well as a boolean describing which phase is being requested. A GeometryProxy is also provided, allowing effects to change based on the view’s geometry. In the following example, the effect will apply a scale of 1.0 to a view when inactive, and then scale to 1.1 when active: struct ScaleHoverEffect: CustomHoverEffect {     func body(content: Content) -> some CustomHoverEffect {         content.hoverEffect { effect, isActive, proxy in             effect.scaleEffect(!isActive ? 1.0 : 1.1)         }     } } Use the animation(_:body:) modifier to specify how visual changes should be animated.
