Bring iOS App to Foreground in WatchKit

I am developing a WatchKit extension for one of my Apps where I really want to have the iPhone App running in the foreground, since it is doing the heavy lifting and is designed to use location services only when active. I know openParentApplication:reply only opens the App in the background (unless it is already active). What I am currently trying out is using a custom URL scheme for my App, and having the App initially open itself from within the handleWatchKitExtension code in the App Delegate. This works perfectly in the Simulator. Unfortunately I did not have this approach ready when I tested my App on real Apple Watches. Does anyone see a problem with this approach to bring the iPhone App to the foreground from the Apple Watch?
