Simple Haptics is a convenience wrapper for Core Haptics to make it easier to fire transient haptic taps, similar to UIFeedbackGenerator.
import SimpleHaptics
let haptics = SimpleHapticGenerator()
try? haptics.fire(intensity: 0.5, sharpness: 1)Simple Haptics works well when integrated with @Environment. You can create a single SimpleHapticGenerator and pass it as an environment object to your root SwiftUI view, then use it in any child views that need haptic feedback. This prevents needing to initialize lots of CHHapticEngines unecessarily, and allows you to stop and start the haptic engine on app lifecycle events. For example, in your SceneDelegate:
import SimpleHaptics
import SwiftUI
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
let haptics = SimpleHapticGenerator()
...
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
let contentView = ContentView()
.environmentObject(haptics) // Pass your haptic generator into your root View.
...
// Be sure to stop the haptic generator when entering the background.
func sceneDidEnterBackground(_ scene: UIScene) {
haptics.stop()
}
func sceneWillEnterForeground(_ scene: UIScene) {
try? haptics.start()
}
}
And then child views can use it simply by creating an @EnvironmentObject variable of the correct type:
import SimpleHaptics
import SwiftUI
struct MyView: View {
@EnvironmentObject private var haptics: SimpleHapticGenerator
...
