Instance Method

aspectRatio(_:contentMode:)

Constrains this view’s dimensions to the specified aspect ratio.

Declaration

func aspectRatio(_ aspectRatio: CGFloat? = nil, contentMode: ContentMode) -> some View

Parameters

aspectRatio

The ratio of width to height to use for the resulting view. If aspectRatio is nil, the resulting view maintains this view’s aspect ratio.

contentMode

A flag indicating whether this view should fit or fill the parent context.

Return Value

A view that constrains this view’s dimensions to aspectRatio, using contentMode as its scaling algorithm.

Discussion

If this view is resizable, the resulting view will have aspectRatio as its aspect ratio. In this example, the purple ellipse has a 3:4 width to height ratio, and scales to fit its frame:

Ellipse()
.fill(Color.purple)
.aspectRatio(0.75, contentMode: .fit)
.frame(width: 200, height: 200)
.border(Color(white: 0.75))
