ios – Supporting Customized Recordsdata with “/” Characters in Swift

My app has a customized file sort, and I am making an attempt to replace my code in order that once I export or import a file that has a “/” character within the title. At the moment the app simply fails to export a file when it has that character within the title.

That is what I’ve for exporting the file:

static func exportDocument(_ doc: StitchDocument) async -> SentTransferredFile {
        log("StitchDocumentWrapper: transferRepresentation: exporting: known as")

        let projectURL = doc.getUrl()
        
        // Use the unique doc title (which can comprise "https://stackoverflow.com/") for the exported file
        let exportedFileName = doc.title + ".sew"
        
        // Create the momentary export URL within the momentary listing
        let tempExportURL = StitchFileManager.tempDir.appendingPathComponent(exportedFileName)

        log("StitchDocumentWrapper: transferRepresentation: projectURL: (projectURL)")
        log("StitchDocumentWrapper: transferRepresentation: tempExportURL: (tempExportURL)")

        do {
            // Take away any current file on the temp export URL
            attempt? FileManager.default.removeItem(at: tempExportURL)
            
            // Zip current undertaking url's contents to the temp export URL
            attempt FileManager.default.zipItem(at: projectURL, to: tempExportURL)

            // Return the SentTransferredFile with the temp file URL
            return SentTransferredFile(tempExportURL)
        } catch {
            log("StitchDocumentWrapper: transferRepresentation: FAILED: error: (error)")
            // In case of error, nonetheless attempt to return a file, nevertheless it won't comprise the right information
            return SentTransferredFile(tempExportURL)
        }
    }

Word that StitchFileManager is a sub-class of FileManager.

The precise drawback is that when the file is exported, it all the time creates extra directories. So, a file named 1/2/3.sew would create a file on the following listing:

file:///Customers/nicholasarner/Library/Containers/app.stitchdesign.sew/Knowledge/tmp/1/2/3.sew

I would like to determine how protect the file title with out creating extra directories because of the inclusion of the / characters.
