Hello, I distributed an App through Ad hoc and was able to install the app through the web server I set up. In my app I need a network connection. But my error handling always tells me that I have no internet connection. Is it possible that there is no Network connection for apps that are distributed through Ad hoc? Thank you for your help Regards, Tell

Hey, I am trying to save the url which I get from my didPickDocumentAt as a security scoped bookmarkThis is my code:Here just the declaration of the UIDocumentPickerViewControllerlet documentPicker = UIDocumentPickerViewController(documentTypes: [kUTTypePlainText as String], in: .open) documentPicker.delegate = self if #available(iOS 11.0, *) { documentPicker.allowsMultipleSelection = false } else { // Fallback on earlier versions } present(documentPicker, animated: true, completion: nil)Now didPickDocumentAt - there I am saving my bookmark data from my selected file on the smb server. Data.bookmarkAdmin is just the variable in which I store the bookmark.func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) { print(url) do { let shouldStoppAccessing = url.startAccessingSecurityScopedResource() defer { if shouldStoppAccessing { url.stopAccessingSecurityScopedResource() } } let bookmarkData: Foundation.Data = try url.bookmarkData() Data.bookmarkAdmin = bookmarkData print(Data.bookmarkAdmin) } catch let error { print(error) } }Later in my app I want to use the bookmark data to create the url again and write on that filefunc readFile() { Admin.fileContent = "" Admin.readString.removeAll() do { var isStale = false let url = try URL(resolvingBookmarkData: Data.bookmarkAdmin, bookmarkDataIsStale: &isStale) guard !isStale else { return } var errorText: Error? do { let didStartAccessing = url.startAccessingSecurityScopedResource() defer { if didStartAccessing { url.stopAccessingSecurityScopedResource() } } print(url) let fileURLs = try FileManager.default.contentsOfDirectory(at: url, includingPropertiesForKeys: nil) Admin.fileContent = try String(contentsOf: fileURLs[0], encoding: .utf8) print("ADMIN: \(Admin.fileContent)") } catch { errorText = error } // Errorhandling if errorText != nil { let alertController = UIAlertController(title: "Error", message: "Keine Datei gefunden \(String(describing: errorText))", preferredStyle: .alert) let okAction = UIAlertAction(title: "ok", style: .default, handler: nil) alertController.addAction(okAction) present(alertController, animated: true, completion: nil) } else {} } catch let error {} }I get an error in my readFile() function ERROR:Error Domain=NSCocoaErrorDomain Code=256 "The file “testaufbau” couldn’t be opened." UserInfo={NSURL=file:///private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/ctPrTwTestApp/testaufbau.csv, NSFilePath=/private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/ctPrTwTestApp/testaufbau.csv, NSUnderlyingError=0x2834bfbd0 {Error Domain=NSPOSIXErrorDomain Code=20 "Not a directory"}}When I set the url manually in the readFile() without the bookmark justlet url: URL = URL(fileURLWithPath: "/private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/ctPrTwTestApp/testaufbau.csv")Then I get a different ERROR: Error Domain=NSCocoaErrorDomain Code=257 "The file “testaufbau.csv” couldn’t be opened because you don’t have permission to view it." UserInfo={NSURL=file:///private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/ctPrTwTestApp/testaufbau.csv, NSFilePath=/private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/ctPrTwTestApp/testaufbau.csv, NSUnderlyingError=0x280ac1440 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}How can I solve this and how do I get permission?

Hey,This is my code. I have the url of the smb server which I have connected in the 'Files' app. It finds the file on the server, but I always says that it has no permission to read it. On my server I have allowed everyone to read and write. Do I need to write something in my code that my app knows that it has permission to read ?let url: URL = URL(fileURLWithPath: "/private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/xVUdQwTestApp/testaufbau.csv") do { let fileURLs = try FileManager.default.contentsOfDirectory(at: url, includingPropertiesForKeys: nil) Admin.fileContent = try String(contentsOf: fileURLs[0], encoding: .utf8) print("ADMIN: \(Admin.fileContent)") } catch { print(error) }Thank you for all the helpRegards,Tell Tobler

Hey,I have been working with the UIDocumenPickerViewController in the last few days.This is my current code:let documentPicker = UIDocumentPickerViewController(documentTypes: [kUTTypePlainText as String], in: .open) documentPicker.delegate = self if #available(iOS 11.0, *) { documentPicker.allowsMultipleSelection = false } else { } present(documentPicker, animated: true, completion: nil)Now my question: After this code I call the didPickDocumentAt MethodedocumentPicker(, didPickDocumentsAt: )But I have no idea what I should put in it, I tried it like thisdocumentPicker(documentPicker, didPickDocumentsAt: [UIDocumentPickerMode.open])I tried it like this but then I always get the Error: Cannot call value of non-function type 'UIDocumentPickerViewController'And my second question is: I want to acces the content of the selected File and found this in the documentation https://developer.apple.com/documentation/uikit/view_controllers/providing_access_to_directoriesIf you go to Access the Directory´s content you find this code// Start accessing a security-scoped resource. guard url.startAccessingSecurityScopedResource() else { // Handle the failure here. return } // Make sure you release the security-scoped resource when you are done. defer { url.stopAccessingSecurityScopedResource() } // Use file coordination for reading and writing any of the URL’s content. var error: NSError? = nil NSFileCoordinator().coordinate(readingItemAt: url, error: &error) { (url) in let keys : [URLResourceKey] = [.nameKey, .isDirectoryKey] // Get an enumerator for the directory's content. guard let fileList = FileManager.default.enumerator(at: url, includingPropertiesForKeys: keys) else { output.append("*** Unable to access the contents of \(url.path) ***\n") return } for case let file as URL in fileList { // Also start accessing the content's security-scoped URL. guard url.startAccessingSecurityScopedResource() else { // Handle the failure here. continue } // Make sure you release the security-scoped resource when you are done. defer { url.stopAccessingSecurityScopedResource() } // Do something with the file here. } }Where do they get the url from in the beginning? The documentation never explains where the url got created.Thank you for your helpRegards,Tell

Hey,so currently I am downloading and import the file I want to read from the smb server through a UIDocumentPickerViewController into the local folder of my app.After that I am able to read this file through the FileManagerThis is how I get the directorylet dir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!and if I want to upload the same file or another file I write into the local folder, I need to manually upload the file to the smb server through the Files App.Is there any way that I can read and write directly to the smb server?How do I get the directory of the server? Is there a path?Thank you for all your help.Regards,Tell. T.
