First you should mark the array as State if you are going to change the data inside the view, or leave it alone, but I choose State for demonstrate:

@State var fakeData = ["Array A", "Array B", "Array C", "Array D"]

Then make a list from it with just one line of code:

List(fakeData, id:\.self) { Text($0) }

Wrap it up:

struct ContentView: View {

    @State var fakeData = ["Array A", "Array B", "Array C", "Array D"]

    var body: some View {
        List(fakeData, id:\.self) { Text($0) }
    }
}

The @State property wrapper does not have to do with "representing UI". It allows the property to be modified within the View body, and triggers a UI update when the property is changed. In other words, you can display static data without the @State property wrapper, and you should only include it on an array if you are dynamically adding or removing elements.
