There is a new #Preview macro (or at least new to me). It s discussed on the SwiftLee blog here. I m excepting some of his code exampled below to ask my question.
To preview your code in the SwiftUI canvas you used to have to code:
struct ContentView: View {
var body: some View {
VStack {
Text("Hello World!")
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
...but now (October 2023) you can code:
struct ContentView: View {
var body: some View {
VStack {
Text("Hello World!")
}
}
}
#Preview {
ContentView()
}
My question is: how do we re-code the following taking into account Apple s #Preview macro syntax so we can change the device-displayed-on-SwiftUI-LivePreview-Canvas programmatically:
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView().previewDevice(PreviewDevice(rawValue: "iPhone SE"))
}
}
The work-around I see is a dropdown graphical interface on the canvas the lets you manually change the displayed device in the Canvas, but is there a way to programmatically do it.
Thank you in advance! The Lord Always Delivers!
