Passing data to Apple Watch app

Solution
This applies to OS 1 only. See below for better answers.
I got it working using your method. I guess there's a couple of things you can check:
1) Are you synchronising the defaults after you set the value:
defaults?.synchronize();
NSLog("%@ ", defaults?.dictionaryRepresentation())
2) Have you enabled the App Group in both your app and your extension?
3) Are you using the correctly named app group when constructing the NSDefaults? For example, I use:
NSUserDefaults(suiteName: "group.com.brindysoft.MyWatch");
Once all that's set up I run the app, set the value in the defaults, then run the glance target which reads the value from the default and that seems to work!
- Still stuck? check your app groups in your apple account
Problem
I am trying to pass data from my app into my Apple Watch app. Basically, I am using the same method as I used for creating the today widget and so I am passing data through NSUserDefaults. The problem is, that when I run my app, the data does not update the labels in the Watch app as I would expect it to. Here is what I have... ``` override init(context: AnyObject?) { // Initialize variables here. super.init(context: context) // Configure interface objects here. NSLog("%@ init", self) var defaults = NSUserDefaults(suiteName: "group.AffordIt") var totalBudgetCalculation = "" if (defaults!.stringForKey("totalBudgetWidget") != nil) { println("Worked") totalBudgetCalculation = defaults!.stringForKey("totalBudgetWidget")! initialBudgetLabel.setText("Initial: \(totalBudgetCalculation)") } var currentBudgetCalculation = "" if (defaults!.stringForKey("currentBudgetWidget") != nil) { currentBudgetCalculation = defaults!.stringForKey("currentBudgetWidget")! currentBudgetLabel.setText("Current: \(currentBudgetCalculation)") } } ``` I tried putting this code in `willActivate()`, however that doesn't seem to make a difference. Anyone know where I am going wrong?
