static var platform: PreviewPlatform
? { get }
Xcode infers the platform for a preview based on the currently selected target. If you have a multiplatform target and want to suggest a particular target for a preview, implement the platform
computed property to provide a hint, and specify one of the Preview
values:
struct CircleImage_Previews: PreviewProvider {
static var previews: some View {
CircleImage()
}
static var platform: PreviewPlatform? {
PreviewPlatform.tvOS
}
}
Xcode ignores this value unless you have a multiplatform target.
