Swift UIDocumentInteractionController doesn't use device language

I'm trying to delegate the opening of a file my app created to an other app using the UIDocumentInteractionController within an UIAlertAction like this:

// variable in the class
var documentController:UIDocumentInteractionController!

// the alertAction
let okAction = UIAlertAction(title: "Öffnen", style: .default, handler: { (_) in
            self.documentController = UIDocumentInteractionController(url: filePath)
            self.documentController.presentOpenInMenu(from: self.view.frame, in: self.view, animated: true)
        })

The Problem is that the UIDocumentInteractionController is always presented in english even though the device-language is something different. Did I miss something? Where can I change the language for the UIDocumentInteractionController?

Solution

  • rmaddy comment to change the Developement-Language worked. Now everything in the UIDocumentInteractionController is displayed in german.
