Creating Complications with ClockKit

WWDC15 Session 209

DO Repeat Yourself

// iOS app struct Session { let startTime: NSDate let endTime: NSDate let description: String let location: String let speaker: Speaker? }

// Watch App struct Session { let startTime: NSDate let endTime: NSDate let location: String let speaker: Speaker? let index: Int }

DO Repeat Yourself

but not too much…

Watch Connectivity

Background Data Transfer

• application context

• application context

• user info transfer

• application context

• user info transfer

• file transfer

Interactive Messaging

• Immediate Information Transfer

• Requires reachable state

WCSession

// check needed for iOS App Only if WCSession.isSupported() { // activate session for both! let session = WCSession.defaultSession() session.delegate = self session.activateSession() }

import WatchConnectivity

class WatchSessionManager: NSObject, WCSessionDelegate { static let sharedManager = WatchSessionManager() private override init() { super.init() } private let session: WCSession? = WCSession.isSupported() ? WCSession.defaultSession() : nil // no need for the check on the Watch App: // private let session = WCSession.defaultSession() func startSession() { session?.delegate = self session?.activateSession() }
