Environment (Values)

---

SwiftUI Data Flow @Environment (Values)

Read system- or app-provided values like color scheme and locale using @Environment.

---

Read environment values (color scheme)

Access the current color scheme from the environment and display it in the UI.

Example

Demo.swift

ContentView.swift

App.swift

import SwiftUI

struct EnvironmentDemo: View {
  @Environment(\.colorScheme) var scheme
  var body: some View {
Text(scheme == .dark ? "Scheme: Dark" : "Scheme: Light")
  .padding()
  }
}

The example above shows a shared object from an ancestor using .environmentObject and consume it in descendants via @EnvironmentObject.
