# projectionEffect(_:)

Applies a projection transformation to this view’s rendered output.

## Declaration

```swift
nonisolated func projectionEffect(_ transform: ProjectionTransform) -> some View

```

## Parameters

- `transform`: A doc://com.apple.SwiftUI/documentation/SwiftUI/ProjectionTransform to apply to the view.

## Discussion

Discussion Use projectionEffect(_:) to apply a 3D transformation to the view. The example below rotates the text 30˚ around the z axis, which is the axis pointing out of the screen: // This transform represents a 30˚ rotation around the z axis. let transform = CATransform3DMakeRotation(     -30 * (.pi / 180), 0.0, 0.0, 1.0)

Text("Projection effects using transforms")     .projectionEffect(.init(transform))     .border(Color.gray)
