struct PreviewDevice

A simulator device that runs a preview. Create a preview device by name, like "iPhone X", or by model number, like "iPad8,1". Use the device in a call to the ``View/previewDevice(_:)`` modifier to set a preview device that doesn't change when you change the run destination in Xcode: struct CircleImage_Previews: PreviewProvider { static var previews: some View { CircleImage() .previewDevice(PreviewDevice(rawValue: "iPad Pro (11-inch)")) } } You can get a list of supported preview device names by using the `xcrun` command in the Terminal app: % xcrun simctl list devicetypes Additionally, you can use the following values for macOS platform development: - "Mac" - "Mac Catalyst"
