Having issue calling function

Developer Tools
1

I am creating a temp out to test different parts of a project. Currently I need to turn something on and off, very basic to start. My issue is that when using the example code for calling a function I run into a compiler error. Does this have something to do with the callFunction method?? Appreciate your help.

Here is the compiler error:
/Users/dan/Desktop/test8/test8/ViewController.swift:18:57: Cannot call value of non-function type ‘((String, [Any]?, ((NSNumber?, Error?) -> Void)?) -> URLSessionDataTask)!’

import UIKit

class ViewController: UIViewController {
var myPhoton : Any?

@IBAction func onButton(_ sender: Any){
    
    let funcArgs = ["D7",1] as [Any]
    var task = (myPhoton! as AnyObject).callFunction("digitalWrite", withArguments: funcArgs) { (resultCode : NSNumber?, error : NSError?) -> Void in
        if (error == nil) {
            println("LED on D7 successfully turned on")
        }
    }
    var bytesToReceive : Int64 = task.countOfBytesExpectedToReceive
}

@IBAction func loginButton(_ sender: Any) {
    
    SparkCloud.sharedInstance().login(withUser: "************", password: "***********")
    print("Logged in")
    
    if SparkCloud.sharedInstance().injectSessionAccessToken("xxxxxxxxxxxx") {
        print("Session is active")
    } else {
        print("Bad access token provided")
    }
    
    
    
    var myPhoton : SparkDevice?
    SparkCloud.sharedInstance().getDevices { (sparkDevices:[Any]?, error:Error?) -> Void in
        if let e = error {
            print("Check your internet connectivity")
        }
        else {
            if let devices = sparkDevices as? [SparkDevice] {
                for device in devices {
                    print(device)
                    if device.name == "photon_1" {
                        myPhoton = device
                    
                    }
                }
            }
        }
    }
    
    
}

@IBAction func offButton(_ sender: Any) {
  
}

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

myPhoton should be typed as a SparkDevice, not Any. funcArgs should also not be typed as Any.

var myPhoton SparkDevice?

@IBAction func onButton(_ sender: Any){

    let funcArgs = ["D7",1] 
    var task = myPhoton!.callFunction("digitalWrite", withArguments: funcArgs) { (resultCode : NSNumber?, error : NSError?) -> Void in
        if (error == nil) {
            println("LED on D7 successfully turned on")
        }
    }
    var bytesToReceive : Int64 = task.countOfBytesExpectedToReceive
}

I’m not sure what example code you’re referring to because the example in the docs (here) shows how to do this correctly.
