Layouts

In addition, you can iterate over a given set of layouts as follows:

    static var previews: some View {
        Layouts([.fixed(width: 200, height: 150), .sizeThatFits, .device]) {
                ContentView()
        }
    }

This is convenient if you have a set of frames you want to set your view up with.

Devices

You can also pass in a set of devices to the Device iterator:

    static var previews: some View {
        Devices([.iPhoneX, .iPhone11]) {
                ContentView()
        }
    }

Thanks to autocompletion you don't have to remember the precise names. Please note that particular care has been taken to transform Apple's fantastic product names into identifiers. For instance:

• iPadPro9·7inch
• iPhoneXʀ
• appleWatchSeries5﹘40mm

Thanks to Swift's support of unicode identifiers you can use these (and thanks to autocomplete you can actually enter them 😅).

You can also use Devices.iPhones (iPads, watches, tvs) to preview all of them:

    static var previews: some View {
        Devices(.iPhones) {
                ContentView()
        }
    }

Please note that these can take a while to render though, so it's not something that's advisable for a screen you use a lot. But it's a great use for a separate file where you set up marketing shots and want them for the full set of devices.

Name parameter

All iterators take an optional name parameter which will add a previewDisplayName with the name and a description of the attribute to the preview.
