32. CONSTRA IN TS • Limited payload 2 kilobytes for iOS 8. 256 bytes for iOS 7 and older • Delivery of notifications is a “best effort”, not guaranteed. It is not intended to deliver data to your app, only to notify the user that there is new data available. • Limited number of custom actions • Limited “styling” options •  Watch Glances and Custom Long-look notifications require a Watch extension • No confirmation that the Notification was displayed to the user 32

34. BEST PR ACTICES - NICK’S T OP 10 1. Guided “Opt In” rather than “Opt Out” 2. Allow user to specify the types of messages they wish to receive. Support DND. Think Time Zone! 3. High volume of Notifications? Consider providing a “Snooze” custom action! 4. Only send relevant messages. This is NOT a direct marketing channel 5. Don't send confidential or sensitive data through push notifications 6. Consider promoting custom actions that do not require the app to start up 7. Use clear language and keep the message short 8. Choose the lowest frequency of notifications that still delivers a great user experience 9. Be aware of context. Is the user in your app right now? 10.Consider aggregating multiple messages into a more generic “group” 34
