Review
New Provider API
Large Device Tokens coming in 2016
- Device tokens today top out at 32 bytes
- Growing up to 100 bytes in 2016
New Provider API:
Four primary features
1. HTTP/2
- Industry standard
- Request-response
- Multiplexed protocol - can send multiple requests in a single connection to a server
- Binary
2. Instant Feedback
Watch video, missed details on this.
3. Simplified Certificate Handling
Previously had to deal with multiple certificates
- Application push
- VOIP push
- Watch Complication Push
- Dev and prod environments
In iOS 9, you just need one certificate instead of multiple.
4. Increasing push notification payload from 2KB to 4KB - part of the New Provider API
