Starting to play around with SwiftUI more in Playgrounds than inside apps. It's faster to get instant feedback and try concepts out. Today, I was prototyping with timers. Here's a shell for getting SwiftUI and Playgrounds working.
import SwiftUI
struct ContentView: View {
var body: some View {
Text("Hello, World")
}
}
import PlaygroundSupport
PlaygroundPage.current.setLiveView(ContentView())
