4. Pros
- Can let your containing iOS app execute some tasks in the
background
- Doesn't matter whether your containing iOS app is currently
running or not
Cons
- If you call multiple times in quick succession, each
subsequent call is delayed
- Should always be triggered by your WatchKit app
7. Pros
- Simple and fast
- Can be used for other extensions, not only WatchKit
Cons
- WatchKit app should be awake to receive immediately
- Keep sending message to WatchKit app to always show the
right data
19. Containing iOS app's Bundle name is for app name in
companion app
WatchKit Extension's Bundle display name is for sash
name
It's weird, so might be changed in the future...
