如何在 SwiftUI 中以横向模式预览设备？
I just have a simple preview like this:
我只有这样一个简单的预览：
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
}
}

You can't rotate the devicein preview (yet), but you can set the size to any landscape size you want for PreviewProvider:
您无法在预览中旋转设备（还），但您可以将尺寸设置为您想要的任何横向尺寸PreviewProvider：
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
.previewLayout(.fixed(width: 568, height: 320)) // iPhone SE landscape size
}
}
This is iPhone SElandscape mode size.
这是iPhone SE横向模式大小。
Note: Since the size is completely custom, Xcode can not infer a device associated to it and will not apply the safe area as you expected for some iPads and iPhones landscape mode.
注意：由于大小是完全自定义的，Xcode 无法推断与其关联的设备，并且不会像您预期的那样为某些 iPad 和 iPhone 横向模式应用安全区域。

ContentView().previewLayout(PreviewLayout.fixed(width:568,height:320))
