Hi @HopkinWatson,
as stated in the documentation of the Exporter :

With this first exporter, Creo can export a Swift project where all views and windows are in it. Logic is not exported yet, just the view hierarchies

You can compile your project directly within Creo, without the need to use Xcode, and send the built App to a real device or submit it to the App Store. The Exporter is recently added feature and it will be improved over time.
