WatchKit Complication: get Complication data from extension delegate

Question

I have all the data I need in my WatchKit Extension (passed from the iOS app).

I used the data in the WatchKit InterfaceController to f

Answer 1

// Get the complication data from the extension delegate.
let myDelegate = WKExtension.sharedExtension().delegate as! ExtensionDelegate
var data : Dictionary = myDelegate.myComplicationData[ComplicationCurrentEntry]!

Above from Apple's Doc is just an example on storing the data you need for your complication in your extension delegate seeing as how you can access it easily as a singleton. The reference to "myComplicationData" is an example of a Dictionary and is not a parameter in the ExtensionDelegate by default.

Either set up your own class as a singleton which holds data for your watch like so:

// Access by calling:
// Model.sharedModel.modelVal1
class Model {
    static let sharedModel = Model()
    var modelVal1: Float!
    var modelVal2: String!
}

Or use the extension delegate as your singleton and add your properties to its class like below. This will allow you to access whatever variables you create in your ExtensionDelegate.

// ExtensionDelegate.swift
class ExtensionDelegate: NSObject, WKExtensionDelegate {
    var dataVar1: Float!
    var dataVar2: String!
    var myDictionary: [String: String]!
}


// ComplicationController.swift
import WatchKit

class ComplicationController: NSObject, CLKComplicationDataSource {

    func someMethod() {
        let myDelegate = WKExtension.sharedExtension().delegate as! ExtensionDelegate
        // Here is an example of accessing the Float variable 
        let accessVar = myDelegate.dataVar1
        let myDict = myDelegate.myDictionary
    }
}

Using either way will help keep your data in one spot so you can always access it from any class in your watch extension.
