Answer 1

You can try this code in your UIInputViewController

override public func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    if let parentViewController = self.parentViewController {
        var hostBundleID = parentViewController.valueForKey("_hostBundleID")
        println(hostBundleID)
    }
}

But I'm not sure that Apple will approved when you release to App Store

Answer 2

ios 16+, "_hostBundleID" the value is nil
