"Error" using FileImporter and FileExporter

Forums > SwiftUI

@Pigna  

Every time I close the "File" modal to import or export a file, using the fileImporter and fileExporter modifier, I get this error/warning

[DocumentManager] The view service did terminate with error: Error Domain=_UIViewServiceErrorDomain Code=1 "(null)" UserInfo={Terminated=disconnect method}

Do you know hot to fix it?

I also get that error message and I could not read the selected file. What sovled my issue was to call startAccessingSecurityScopedResource and then copy file to a temporary folder. Once file is copied it can be used with no issues. The error message is still there but at least I can access the file.

The code is ugly, so please do your housekeeping.

 .fileImporter(
            isPresented: $showImageFilePicker,
            allowedContentTypes: [.image],
            allowsMultipleSelection: false
        ) { result in
            do {
                guard let selectedFile: URL = try result.get().first else { return }

                guard selectedFile.startAccessingSecurityScopedResource() else {
                    // Handle the failure here.
                    return
                }

                let documentsUrl =  FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask).first!
                let destinationUrl = documentsUrl.appendingPathComponent(selectedFile.lastPathComponent)

                if let dataFromURL = NSData(contentsOf: selectedFile) {
                    if dataFromURL.write(to: destinationUrl, atomically: true) {
                        print("file saved [\(destinationUrl.path)]")
                        selectedImageURL = destinationUrl
                    } else {
                        print("error saving file")
                        let error = NSError(domain:"Error saving file", code:1001, userInfo:nil)
                    }
                }

                selectedFile.stopAccessingSecurityScopedResource()

            } catch {
                print(error)
            }
        }
