In watch os 2 you need to use session for transferring the data between watch & iPhone.
First you need to initialise the WCSession in viewdidload()
if (WCSession.isSupported()) {
let session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
}
then to send the data you can use
let transfer = WCSession.defaultSession().transferUserInfo(applicationDict)
Then, on the receiving end, you'll need to implement session:didReceiveUserInfo: (Developer documentation). Note, according to Apple's "watchOS2 Transition Guide,"
To begin communication, both your Watch app and your iOS app must have an active WCSession object. Typically, each app creates, configures, and activates a session object at launch time and stores a reference to it in a central location. When you want to send data, you retrieve the session object and call its methods.
