Do I need to dismiss UIDocumentPickerViewController even when the enduser choses a file?

From a tutorial I pulled the extension below to allow the enduser to select a file off of the iPhone's storage system.

Everything works fine.

However I noticed that in the delegate that "dismiss" is only being called if the user chooses cancel. While the view does disappear when a file is selected, I am not sure that the view is being properly dismissed internally by Swift.

Since I do call present, am I responsible for dismissing it when the user chooses a file as well?

let supportedTypes: [UTType] = [UTType.item]
let pickerViewController = UIDocumentPickerViewController(forOpeningContentTypes: supportedTypes)
pickerViewController.delegate = self
pickerViewController.allowsMultipleSelection = false
present(pickerViewController, animated: true, completion: nil)

extension uploadFile:  UIDocumentPickerDelegate {
	
	func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
		
		for url in urls {
			guard url.startAccessingSecurityScopedResource() else {
				print ("error")
				return
			}
			
			...save chosen file url here in an existing structre
			
			do { url.stopAccessingSecurityScopedResource() }
		}
	}
	
	func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
		controller.dismiss(animated: true, completion: nil)
	}
}
