SF Symbols

A couple of times in the App Development seminar I went to, we used system symbols in the place of images, and in his tutorial on Swift UI Basics, Sean Allen spent a few minutes talking about where they come from and how to choose them.

First, here’s how they look in code - this is from the default Hello World app.

struct ContentView: View {
    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text("Hello world")
        }
    }
}
