To schedule local notifications in Swift, you need to use the User Notifications framework. First, make sure to request permission from the user to send notifications. Once you have permission, you can create and schedule notifications. Below is an example of how to implement local notifications in a Swift application:
import UserNotifications
// Request permission to show notifications
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
if granted {
print("Permission granted")
} else {
print("Permission denied")
}
}
// Schedule a notification
func scheduleNotification() {
let content = UNMutableNotificationContent()
content.title = "Hello!"
content.body = "This is a local notification."
content.sound = UNNotificationSound.default
// Trigger the notification in 5 seconds
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request) { error in
if let error = error {
print("Error adding notification: \(error.localizedDescription)")
} else {
print("Notification scheduled!")
}
}
}
