Syncing

Data with Watch

Curt Clifton—The Omni Group. Jan 8, 2015, Seattle Xcoders 15

SLIDE 16

Your watch extension is a separate process from your iPhone app; you just signed up for data syncing.

Watch apps die easily; network

perations are

right out.1

SLIDE 18 What’s a developer to do? — File coordination? Nope. — App Group entitlement and user defaults — Shared CoreData database — Shared SQLite database — Seed file & callbacks Curt Clifton—The Omni Group. Jan 8, 2015, Seattle Xcoders 18

Syncing Using Seed File & Callbacks

SLIDE 22 Syncing Data with Watch — Your watch extension is a separate process from your iPhone app; you just signed up for data syncing. — Watch apps die easily; network operations are right out.1 1 Monty Python and the Holy Grail Curt Clifton—The Omni Group. Jan 8, 2015, Seattle Xcoders 22

SLIDE 23

Debugging Watch Apps

— Run iPhone app first — Open Watch “external display” — Launch the WatchKit app — In the simulator, tap the iPhone app — In Xcode, connect to the iPhone app — Use Console to watch Simulator’s system log Curt Clifton—The Omni Group. Jan 8, 2015, Seattle Xcoders 23

Challenges

Curt Clifton—The Omni Group. Jan 8, 2015, Seattle Xcoders 24

SLIDE 25 Challenges — Sending UI commands to non-active controls — Using shared frameworks — Selecting watch menu items crashes the simulator eventually — No auto layout? — Notifications while watch app is running? Curt Clifton—The Omni Group. Jan 8, 2015, Seattle Xcoders 25
