# hoverEffect(in:isEnabled:body:)

Creates a hover effect that applies effects to a view using the given closure.

## Declaration

```swift
static func hoverEffect<C>(in group: HoverEffectGroup? = nil, isEnabled: Bool = true, body: @escaping (EmptyHoverEffectContent, Bool, GeometryProxy) -> C) -> ContentHoverEffect<C> where Self == ContentHoverEffect<C>, C : HoverEffectContent
```

## 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 will not become active when hovered.
- `body`: The closure that constructs a HoverEffectContent for each of the effect’s phases.

## Return Value

Return Value A new effect that applies effects to a view using the given body closure.

## Discussion

Discussion The closure is provided an empty effect that you use to compose effects, 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. Typically the CustomHoverEffect/hoverEffect(in:isEnabled:body:) or hoverEffect(in:isEnabled:body:) modifiers are used to create effects. Use this method when you need to create effects in other contexts. For example, the following code uses this method and HoverEffect to create a type-erased fade effect: HoverEffect(     .hoverEffect { e, isActive, _ in         e.opacity(isActive ? 1 : 0)     } )
