Instance Method


Sets the transparency of this view.


func opacity(_ opacity: Double) -> some View



A value between 0 (fully transparent) and 1 (fully opaque).

Return Value

A view that sets the transparency of this view.

When applying the opacity(_:) modifier to a view that already has an opacity, the modifier supplements—rather than replaces—the view’s opacity.
