Simple Local Reminder

Goal

Request permission (if needed) and schedule a local notification after a time interval.

Actions used

• NotificationServicesGetSettings

• NotificationServicesRequestPermission

• NotificationServicesGetRequestPermissionError (optional)

• NotificationServicesCreateBuilder

• NotificationServicesScheduleNotification

• NotificationServicesGetScheduleNotificationError (optional)

Variables

• permissionStatus (Enum: NotificationPermissionStatus) ← NotificationServicesGetSettings.status

• title (String)

• body (String)

• delaySeconds (Float)

Flow

1. State: GetSettings

   • Action: NotificationServicesGetSettings → status (store into permissionStatus)

   • Branch using an Enum Compare/Switch on permissionStatus:

     • Authorized / Provisional → BuildNotification

     • NotDetermined → RequestPermission

     • Denied → show “Enable notifications in Settings” and stop

2. State: RequestPermission

   • Action: NotificationServicesRequestPermission (choose your options, e.g., Alert/Badge/Sound)

   • Events:

     • grantedEvent → BuildNotification

     • deniedEvent → show error

     • failureEvent → GetRequestPermissionError (optional) then show error

3. State: BuildNotification

   • Action: NotificationServicesCreateBuilder

   • Example inputs:

     • notificationId: "reminder_1"

     • title: title

     • body: body

     • triggerType: TimeInterval

     • timeInterval: delaySeconds

     • repeats: false

     • soundFileName: "default" (optional)

4. State: Schedule

   • Action: NotificationServicesScheduleNotification

   • Events:

     • successEvent → done

     • failureEvent → GetScheduleNotificationError (optional) then show error

Notes

• NotificationServicesCreateBuilder only builds/caches the notification; NotificationServicesScheduleNotification actually schedules it.

• If permission is denied, iOS won’t show the system prompt again; users must enable it from device Settings.
