iOS Notifications

Priority: P2 (MEDIUM)

Guidelines

• Framework: Use UserNotifications for all notification handling.
• Delegate: Implement UNUserNotificationCenterDelegate for foreground & tap handling.
• Permissions: Request .alert, .badge, .sound after priming user.
• APNs: Register for remote notifications in AppDelegate.
• Badges: Manage app icon badges manually (set to 0 to clear).

See APNs registration and permission examples

Anti-Patterns

• No Unconditional Requests: Explain value proposition before system dialog.
• No Missing Delegate: Notifications won't trigger foreground callbacks without it.
• No Forgotten Badge Clear: User frustration increases if badges persist.
