I want to save the URL of an iCloud Document in an CoreData Object. In order to pick the file i use the following code:

.fileImporter(
                isPresented: $isImporting,
                allowedContentTypes: [.jpeg, .png],
                allowsMultipleSelection: false
            ) { result in
                do {
                    let selectedFile : URL = try result.get().first!
                    if (FileManager.default.isUbiquitousItem(at: selectedFile)) {
                        /* USE URL */
                    }else{
                        /* ERROR ALERT Not an iCloud FIle */
                    }
                }catch{
                    /* ERROR Handling */
                }

            }

The result now contains a absolute URL like:

file:///Users/USER/Library/Developer/CoreSimulator/Devices/SIMULATOR_DEVICE_ID/data/Library/Mobile%20Documents/com~apple~CloudDocs/Folder/File.png

Is there a standardized way to convert this URL into the following relative iCloud Documents Path: "Folder/File.png"?
