I am working on a personal use app, to transcribe audio files. I have over 1000 Voice Memos of ideas for a dog training app and book, recorded while... walking dogs, of course. I seem to not have the built in transcription option, either because Sonoma doesn't support it or my region doesn't, but I have learned a lot of Swift building an app that works great fort files in a folder in Documents. I have also found the path to to all the Voice Memo recordings. But when I try to read the contents of the folder to build the queue for transcription I get The file “Recordings” couldn’t be opened because you don’t have permission to view it. I expected this to be locked down, and some searching brought me to this and I have added Access User Selected Files (Read Only) = YES to the entitlements file, but I am not seeing where in the TARGETS editor I would assign com.apple.security.files.user-selected.read-only. If I add it as a key under info I don't get a popup to select, either in Xcode or when running the app. If I try to add that key to the entitlements file it doesn't allow for selection either. I am sure I am just missing something in the documentation, likely as a result of being an Xcode & Swift noob. So, if I CAN do this and I am just missing something, can someone point the way? And if a folder inside another app is just verboten, manually copying those files to a documents folder for processing won't be the end of the world.

I am attempting to do batch Transcription of audio files exported from Voice Memos, and I am running into an interesting issue. If I only transcribe a single file it works every time, but if I try to batch it, only the last one works, and the others fail with No speech detected. I assumed it must be something about concurrency, so I implemented what I think should remove any chance of transcriptions running in parallel. And with a mocked up unit of work, everything looked good. So I added the transcription back in, and 1: It still fails on all but the last file. This happens if I am processing 10 files or just 2. 2: It no longer processes in order, any file can be the last one that succeeds. And it seems to not be related to file size. I have had paragraph sized notes finish last, but also a single short sentence that finishes last. I left the mocked processFiles() for reference. Any insights would be greatly appreciated. import Speech import SwiftUI struct ContentView: View { @State private var processing: Bool = false @State private var fileNumber: String? @State private var fileName: String? @State private var files: [URL] = [] let locale = Locale(identifier: "en-US") let recognizer: SFSpeechRecognizer? init() { self.recognizer = SFSpeechRecognizer(locale: self.locale) } var body: some View { VStack { if files.count > 0 { ZStack { ProgressView() Text(fileNumber ?? "-") .bold() } Text(fileName ?? "-") } else { Image(systemName: "folder.badge.minus") Text("No audio files found") } } .onAppear { files = getFiles() Task { await processFiles() } } } private func getFiles() -> [URL] { do { let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first! let path = documentsURL.appendingPathComponent("Voice Memos").absoluteURL let contents = try FileManager.default.contentsOfDirectory(at: path, includingPropertiesForKeys: nil, options: []) let files = (contents.filter {$0.pathExtension == "m4a"}).sorted { url1, url2 in url1.path < url2.path } return files } catch { print(error.localizedDescription) return [] } } private func processFiles() async { var fileCount = files.count for file in files { fileNumber = String(fileCount) fileName = file.lastPathComponent await processFile(file) fileCount -= 1 } } // private func processFile(_ url: URL) async { // let seconds = Double.random(in: 2.0...10.0) // await withCheckedContinuation { continuation in // DispatchQueue.main.asyncAfter(deadline: .now() + seconds) { // continuation.resume() // print("\(url.lastPathComponent) \(seconds)") // } // } // } private func processFile(_ url: URL) async { let recognitionRequest = SFSpeechURLRecognitionRequest(url: url) recognitionRequest.requiresOnDeviceRecognition = false recognitionRequest.shouldReportPartialResults = false await withCheckedContinuation { continuation in recognizer?.recognitionTask(with: recognitionRequest) { (transcriptionResult, error) in guard transcriptionResult != nil else { print("\(url.lastPathComponent.uppercased())") print(error?.localizedDescription ?? "") return } if ((transcriptionResult?.isFinal) == true) { if let finalText: String = transcriptionResult?.bestTranscription.formattedString { print("\(url.lastPathComponent.uppercased())") print(finalText) } } } continuation.resume() } } }

First off, given that I didn't find a tag for Code Review, I hope I am not out of scope for the forums here. Second, some background. I am a long time Windows Power Shell developer, moving to Swift because I don't like self loathing. :) Currently I am trying to get my head around SwiftData, and experimenting with creating a Service to handle the actual SwiftData functionality, and a Manager to handle various tasks that relate to instances of the Model. I am doing this realizing that it MAY NOT be the best approach, but it gives me reps both producing code and thinking about how to solve a problem, which I think is useful even if the actual product in throw away. That said, I am hoping someone with more experience than I can comment on this approach, especially with respect to expanding to more models, more complex models, lots of data and a desire to use ModelActor eventually. DataManagerApp.swift import SwiftData import SwiftUI @main struct DataManagerApp: App { let container: ModelContainer init() { let schema = Schema([DataModel.self]) let config = ModelConfiguration("SwiftDataStore", schema: schema) do { let modelContainer = try ModelContainer(for: schema, configurations: config) DataService.instance.assignContainer(modelContainer) container = modelContainer } catch { fatalError("Could not configure SwiftData ModelContainer.") } } var body: some Scene { WindowGroup { ContentView() .modelContainer(container) } } } DataModel.swift import Foundation import SwiftData @Model final class DataModel { var date: Date init(date: Date) { self.date = date } } final class DataService { static let instance = DataService() private var modelContainer: ModelContainer? private var modelContext: ModelContext? private init() {} func assignContainer(_ container: ModelContainer) { if modelContainer == nil { modelContainer = container modelContext = ModelContext(modelContainer!) } else { print("Attempted to assign ModelContainer more than once.") } } func addModel(_ dataModel: DataModel) { modelContext?.insert(dataModel) } func removeModel(_ dataModel: DataModel) { modelContext?.delete(dataModel) } } final class ModelManager { static let instance = ModelManager() let dataService: DataService = DataService.instance private init() {} func newModel() { let newModel = DataModel(date: Date.now) DataService.instance.addModel(newModel) } } ContentView.swift import SwiftData import SwiftUI struct ContentView: View { @Environment(\.modelContext) var modelContext @State private var sortOrder = SortDescriptor(\DataModel.date) @Query(sort: [SortDescriptor(\DataModel.date)]) var models: [DataModel] var body: some View { VStack { addButton List { ForEach(models) { model in modelRow(model) } } .listStyle(.plain) } .padding() .toolbar { ToolbarItem(placement: .topBarTrailing) { addButton } } } } private extension ContentView { var addButton: some View { Button("+ Add") { ModelManager.instance.newModel() } } func modelRow(_ model: DataModel) -> some View { HStack { Text(model.date.formatted(date: .numeric, time: .shortened)) Spacer() } } }

I am trying to get my head around SwiftData, and specifically some more "advanced" ideas that I have not seen covered in the various tutorials. Specifically, I have a class that includes a collection that may or may not contain elements. For now I am experimenting with a simple array of Date, and I don't know if I should make it an optional, or an empty array. Without SwiftData in the mix it seems like it's probably programmers choice, but I wonder if SwiftData handles those two scenarios differently, that would suggest one over the other.
