How to hide Today widget on app first run?

Question

I'm wondering how to hide a Today widget on the app's first run.

I don't want to hide it from application(_:didFinishLaunchingWithOptions:) but rather from the widget's info.plist or lifecycle methods in order to decouple the AppDelegate from widget logic.

Does anyone have any idea how to do this?

From Apples documentation

Typically, a widget appears in the Today view when it has content to display. If a currently running widget no longer has content to display, it can get a widget controller and set to false the flag in the setHasContent:forWidgetWithBundleIdentifier: method.

What you could do is to do the following:

Check by NSUserDefaults if it´s the first time the app is running and in the set setHasContent:forWidgetWithBundleIdentifier to false. Code example below:

if !NSUserDefaults.standardUserDefaults().boolForKey("firstRun"){
    // first run so do set setHasContent:forWidgetWithBundleIdentifier to false

    // Set your NSUserDefaults firstRun value to false so it does not run again
    NSUserDefaults.standardUserDefaults().setBool(true, forKey: "firstRun")
}
