How do I throttle button taps in SwiftUI with Swift?

Throttling button taps in SwiftUI is essential to prevent multiple rapid actions that might lead to unintended behavior in your app. This can enhance user experience by ensuring that user inputs are managed more effectively.

In the example below, we implement a throttling mechanism using a custom view modifier that limits the frequency of button taps in SwiftUI.

struct ThrottledButton: View { let action: () -> Void let label: Label @State private var lastTap: Date = .distantPast let delay: TimeInterval init(delay: TimeInterval, action: @escaping () -> Void, @ViewBuilder label: () -> Label) { self.delay = delay self.action = action self.label = label() } var body: some View { Button(action: { let now = Date() if now.timeIntervalSince(lastTap) > delay { lastTap = now action() } }) { label } } } // Usage struct ContentView: View { var body: some View { ThrottledButton(delay: 1.0, action: { print("Button tapped!") }) { Text("Tap me") } } }
