How to launch a parent iOS App from its App Extension

Question

Does any one know how to launch the parent app from the app extension\'s view controller?

I just want to launch the main app from its app extension.

Working solution in Swift 3.1 (tested in iOS10):

You need to create your own URL Scheme for your host app, then add this function to your ViewController and call it with openURL("myScheme://myIdentifier")

//  Function must be named exactly like this so a selector can be found by the compiler!
//  Anyway - it's another selector in another instance that would be "performed" instead.
func openURL(_ url: URL) -> Bool {
    var responder: UIResponder? = self
    while responder != nil {
        if let application = responder as? UIApplication {
            return application.perform(#selector(openURL(_:)), with: url) != nil
        }
        responder = responder?.next
    }
    return false
}
