Problems with Watchkit Extension NSURLSession in Swift

I'm trying to call my local API to turn off my house lighting from my watch, but I'm having trouble with calling a url from within the watchkit extension.

In my ViewController (iPhone app) I've got exactly the same code (which works), but somehow it doesn't work when I call it in the InterfaceController from the Watchkit Extension.

@IBAction func confirmTapped() {

    let url = NSURL(string: "http://homeserver.local/api/lights/4/0")
    let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in
        print(NSString(data: data!, encoding: NSUTF8StringEncoding))
    }

    task!.resume()
}

I've also attached a gist: https://gist.github.com/f72125cd4678069af7af.git

Am I missing something obvious?

Solution

  • I don't know if it's a good thing to start a NSURLSession from within the Watch extension. If the request takes to long, it will be cancelled.

    Maybe you could ping the watch via openParentApplication:reply and handle the NSURLSession on your iPhone app.
