ViewController init should be init?

[simonxcheng]

In the VeiwController.swift, the init should be failable:

required init?(coder aDecoder: NSCoder) {
self.session = WCSession.defaultSession()
super.init(coder: aDecoder)
}

Definitely a reasonable assessment. If you've got time to do a PR I'd merge it in. Otherwise, I'm going to be revisiting this stuff hopefully this week and I can make the change then.

Thank you for catching this.
