Live Activities in Swift using ActivityKit allow developers to provide real-time updates directly on the lock screen or in the Dynamic Island for ongoing tasks or events. This can greatly enhance user engagement by keeping them informed about important events without needing to open an app.
Here's a simple example of how to integrate Live Activities using ActivityKit:
// Import the necessary framework
import ActivityKit
// Define a structure for your Activity's content state
struct MyActivityAttributes: ActivityAttributes {
public typealias Status = ContentState
public struct ContentState: Codable, Hashable {
var progress: Double
}
var title: String
}
// Create and start a Live Activity
func startLiveActivity() {
let attributes = MyActivityAttributes(title: "Downloading...")
let initialContentState = MyActivityAttributes.ContentState(progress: 0.0)
let activity = try? Activity.request(attributes: attributes, contentState: initialContentState, pushType: nil)
}
// Update the Live Activity
func updateLiveActivity(progress: Double) {
let updatedState = MyActivityAttributes.ContentState(progress: progress)
Task.init {
let activity = Activity.activities.first
await activity?.update(using: updatedState)
}
}
