It's Apple Watch time! We are having a combined meetup with the Advanced iOS meetup.

After the Apple Watch is released, we’ve come together to learn a few new features from WatchKit and test out the physical hardware.

Having played with the Watches extensively, we'll discuss impressions and developer advice.

5. fetching data from server 1. user launches watch app 2. bluetooth communication to WatchKit extension 3. extension needs data from iPhone app 4. not running yet in background 5. openParentApplication:reply: called, launches app 6. parent app takes request and calls API on server 7. API processes request & responds back to app 8. parent app processes data & hands off to extension 9. extension renders table cells & sends to watch
6. even short wait times can significantly impact user dropoff
7. NOT a smaller version of the iPhone app ~ instead it is a view of some of the iPhone app’s data
8. background fetch new data account updates shared container
9. container shared container
10. shared container
14. best practices for speed 1. iPhone prepares new data for watch in bg 2. watch uses only subset of full database 3. watch only renders the data it already has 4. images PNG-9, non-transparent, 32 colors 5. images exact size 6. single anim. per screen w/ mask to hide 7. only execute one tap at a time
