Use Swift Playgrounds to sketch ideas
Before spinning up a whole Swift project, use Swift Playgrounds to sketch out ideas.
In Xcode (macOS):
File -> New -> Playground
- Choose “Single View” (I’m not sure what impact picking macOS or iOS has)
- Choose a name and location to save your playground
UIKit is the iOS default for a single-view playground. Storybooks are the default for macOS. To replace those with a SwiftUI component:
import SwiftUI
import PlaygroundSupport
struct ContentView: View {
var body: some View {
VStack {
Button("Tap me!") {
}
}
}
}
let contentView = ContentView()
PlaygroundPage.current.setLiveView(contentView)
🤔 I haven’t yet come upon a good heuristic for:
- when to spin up a project for tinkering vs. a playground
- to what extent one could use TDD in playgrounds
- how to import files from a playground inside a project and use project resources
