Hi everyone, I'm working on a Vision Pro application and encountering an issue while trying to load a USDZ file. Here are the details: File Path: /Users/siddharthpatel/Library/Developer/CoreSimulator/Devices/31F10013-50B6-4CEF-9388-9094087FAEBF/data/Containers/Data/Application/EB260F0A-A84F-4E95-876D-08199D2A4998/Documents/hive1.usdz Code: do { try await modelEntityForCollider = ModelEntity(contentsOf: fileURL!) } catch { print("Error loading model: (error)") } Error: Thread 1: Fatal error: Failed to import entity from "/Users/siddharthpatel/Library/Developer/CoreSimulator/Devices/31F10013-50B6-4CEF-9388-9094087FAEBF/data/Containers/Data/ ... ve1.usdz" I've verified that the file path is correct and the USDZ file exists at the specified location. What could be causing this error and how can I resolve it? Thanks in advance for your help! Siddharth

I'm trying to get the url out of a binary webloc file, but I'm getting the follow error: NSURLConnection finished with error - code -1002. error: The file “link.webloc” couldn’t be opened. Does anyone know how to read a binary webloc file with swift? func readFile() { if let path = Bundle.main.path(forResource: "link", ofType: "webloc") { print("path: \(path)") if let url = URL(string: path) { do { let data = try Data(contentsOf: url) let plist = try PropertyListSerialization.propertyList(from: data, options: [], format: nil) print("plist") } catch { print("error: \(error.localizedDescription)") } } } } I made a git repo of the project if anyone want to try it out. https://github.com/syclonefx/ReadWeblocFile. I have 2 different webloc files the link.webloc is a binary webloc file and the link2.webloc is a text webloc file

Hello All, some background information first. I have the following struct: Struct Category: Identifiable, Codeable, Hashable { var id: UUID var name: String var subCategory: [Category]? } var categories: [Category] There is no limit how many levels deep the subcategory can be. The user is essentially creating a hierarchical data filing system. Given that the number of subCategory levels is unlimited, I am recursing over the subcategories to find the correct level at which to insert the newCategory. The recursive function to add category is declared as: func recursiveAddCategory(newCategory: Category, subCategoryOf: inout [Category]?) you will note that I am trying to pass the subCategory as a reference (using inout), so that I can add to the original and the function is called as recursiveAddCategory(newCategory, &categories.subCategory!) the actual append statement within the recursiveAddCategory function is: categories.subCategory?.append(newCategory) I am encountering no errors but also find that the newCategory is not being added to the categories array. Any help or guidance appreciated. Thanks

I want to provide my own thumbnails for the file types which System already provides thumbnails for. I tried using QLThumbnailProvider however it works only when the file type is custom. For system supported file types it doesn't allow me to override my own thumbnails. Is there any alternative to this?

I'm experiencing a new error in SwiftData since updating to Xcode 16/iOS 17 DB1. When passing in a model (Student) to a view and then displaying an array of Points using ForEach, I get the following fatal error: SwiftData/ModelCoders.swift:2438: Fatal error: Failed to locate relationship for StringCodingKey(stringValue: "group", intValue: nil) on Entity - name: Point superentity: subentities: storedProperties: CompositeAttribute - name: type, options: [], valueType: PointType, defaultValue: nil Properties: Attribute - name: type, options: [], valueType: String, defaultValue: nil, hashModifier: nil Relationship - name: outcome, options: [], valueType: Outcome, destination: Outcome, inverseName: nil, inverseKeypath: nil CompositeAttribute - name: proficiency, options: [], valueType: Proficiency, defaultValue: nil Properties: Attribute - name: proficiency, options: [], valueType: String, defaultValue: nil, hashModifier: nil Attribute - name: date, options: [], valueType: Date, defaultValue: nil, hashModifier: nil Attribute - name: note, options: [], valueType: String, defaultValue: nil, hashModifier: nil Relationship - name: student, options: [], valueType: Optional<Student>, destination: Student, inverseName: points, inverseKeypath: Optional(\Student.points) Attribute - name: group, options: [], valueType: Array<PersistentIdentifier>, defaultValue: [], hashModifier: nil inheritedProperties: uniquenessConstraints: indices: Xcode flags this line of the macro-generated getter of the outcome property on Point: @storageRestrictions(accesses: _$backingData, initializes: _outcome) init(initialValue) { _$backingData.setValue(forKey: \.outcome, to: initialValue) _outcome = _SwiftDataNoType() } get { _$observationRegistrar.access(self, keyPath: \.outcome) return self.getValue(forKey: \.outcome) // Fatal error: Failed to locate relationship for StringCodingKey... } set { _$observationRegistrar.withMutation(of: self, keyPath: \.outcome) { self.setValue(forKey: \.outcome, to: newValue) } } This worked just fine in iOS 17. Here's a snippet of the Student implementation: @Model class Student: Identifiable, Comparable { var name: String var number: Int @Relationship(deleteRule: .cascade, inverse: \Point.student) var points: [Point] @Relationship(deleteRule: .cascade, inverse: \Mark.student) var marks: [Mark] @Relationship(deleteRule: .nullify, inverse: \StudentGroup.students) var groups: [StudentGroup] = [] var archived: Bool } and the implementation of Point: @Model class Point: Identifiable, Comparable { var student: Student? var type: PointType var outcome: Outcome var proficiency: Proficiency var group: [Student.ID] = [] var date: Date var note: String } and finally the implementation for Outcome: @Model class Outcome: Identifiable, Comparable { var name: String var index: Int var rubric: Rubric? var proficiencies: [Proficiency] } I've tried adding a relationship in Outcome as an inverse of the outcomes property on Points (although this does not make sense in my implementation, which is why I initially did not set a relationship here) and the problem persisted. Any ideas what this error means and how I might go about fixing it?

I have a simple SwiftUI app that has a picker, textfield and several buttons. It is using a Enum as a focus state for the various controls. When I compile and run it on Mac Studio desktop it works as expected: Picker has initial focus, Selection in Picker changes focus to TextField, Tab key moves through buttons; last button resets to Picker However when I run the exact same app on MacBook Pro (same version of MacOS, 14.5) it does not work at all as expected. Instead: Initial focus is set to TextField, Tab does not change the focus, Clicking on last button resets focus to TextField rather than Picker The content view code: enum FFocus: Hashable { case pkNames case btnAssign case tfValue case btn1 case btn2 case noFocus } struct PZParm: Identifiable { var id = 0 var name = "" } struct ContentView: View { @State var psel:Int = 0 @State var tfVal = "Testing" @FocusState var hwFocus:FFocus? var body: some View { VStack { Text("Hardware Test").font(.title2) PPDefView(bSel: $psel) .focused($hwFocus, equals: .pkNames) TextField("testing", text:$tfVal) .frame(width: 400) .focused($hwFocus, equals: .tfValue) HStack { Button("Button1", action: {}) .frame(width: 150) .focused($hwFocus, equals: .btn1) Button("Button2", action: { tfVal = "" hwFocus = .tfValue }) .frame(width: 150) .focused($hwFocus, equals: .btn2) Button("New", action: { tfVal = "" hwFocus = .pkNames }) .frame(width: 150) .focused($hwFocus, equals: .btnAssign) } } .padding() // handle picker change .onChange(of: psel, { if psel > 0 {hwFocus = .tfValue} }) .onAppear(perform: {hwFocus = .pkNames}) } } #Preview { ContentView() } struct PPDefView: View { @Binding var bSel:Int // test defs let pzparms:[PZParm] = [ PZParm.init(id:1, name:"Name1"), PZParm.init(id:2, name:"Name2") ] // var body:some View { Picker(selection: $bSel, label: Text("Puzzle Type")) { ForEach(pzparms) {Text($0.name)} }.frame(width: 250) } }

I am working thru the issues of turning on Strict Concurrency Checking. I have a SwiftData application, and I am compressing images before saving them as data. My save function is pretty simple private func save() { ImageCompressor.compress(image: (frontImageSelected?.asUIImage())!, maxByte: 1_048_576) { image in guard image != nil else { print("Error compressing image") return } if let greetingCard { greetingCard.cardName = cardName greetingCard.cardFront = image?.pngData() greetingCard.cardManufacturer = cardManufacturer greetingCard.cardURL = cardURL greetingCard.eventType = eventType } else { let newGreetingCard = GreetingCard(cardName: cardName, cardFront: image?.pngData(), eventType: eventType, cardManufacturer: cardManufacturer, cardURL: cardURL) modelContext.insert(newGreetingCard) } } } I compress the selected image, I had to change my ImageCompressor.compress closure to Sendable, but now every assignment above is flagging with the above warning. I define the greetingCard as var greetingCard: GreetingCard? in my view, since I can have it passed in for edit, or generated if new. I also get the same warning on modelContext, which is defined as @Environment(\.modelContext) private var modelContext. It's not clear to me how to address this warning. Any pointers would be helpful.

Hi, Please let me know iOS 18 beta have deprecated/ stopped support for which of the following: proximityUUID CLBeaconRegion (instancetype)initWithProximityUUID:(NSUUID *)proximityUUID identifier:(NSString *)identifier (void)startRangingBeaconsInRegion:(CLBeaconRegion *)region -startRangingBeaconsSatisfyingConstraint: , is this also deprecated in iOS 18 beta, since: CLBeaconIdentityConstraint is deprecated right? CLBeaconIdentityCondition is not supported in XCode 15.3. What should I do for this? Should I install XCode 16 beta? locationManager:didRangeBeacons:satisfyingConstraint: can we use it in iOS 18 beta, since, CLBeaconIdentityConstraint is deprecated? what is alternative startMonitoring(for:) is also deprecated in iOS 18 beta right? Also, can someone specify or create a documentation on how beaconing shall be monitored, ranged and locationManager delegate methods pertaining to beaconing to be used in iOS 18 beta?

Hi, When using Swift Concurrency blocking tasks like file I/O, GPU work and networking can prevent forward moving progress and have the potential to exhaust the cooperative thread pool and under utilize the CPU. It's been recommended to offload these tasks from the cooperative thread pool. Is my understanding correct that the preferred way to do this is by creating async tasks via Dispatch or OperationQueue? And combining these with Continuations if a return value from the task is required? Or should I always be using Continuations in combination with Dispatch/OperationQueue? There are also Executors but the documentation seems a bit limited on how to use these. The new TaskExecutor is also only available on the latest beta's. My question is basically what is the recommend way to offload a task? Thanks!

struct Preview: View { private static let NAME = "Test" @Query(filter: #Predicate<Item> { $0.name == Preview.NAME}) private var items: [Item] var body: some View { MyView(name: Preview.NAME, items: items) } } Compile error occurs: key path cannot refer to static member 'NAME' How can a (static) constant be referred in member closure?

Hello By default if swiftData is unable to open a file on mac (due to it being the wrong format, or an old model) the app hard crashes (macOS 14.4.1) - is there a way to catch this problem and present a message to the user, rather than the app simply crashing The whole way that swiftData opens files etc is very opaque so I'm not clear how we can wrap things in a nice way Thanks Richard

In my method moveSun() it successfully rotates and plays the sound the first time it is called. However, subsequent calls to the method only play the sound and do not execute the rotate action. Does anyone know what may be causing this? Here's the relevant code: func moveSun() { print(sunMoving) let rotateAction = SKAction.rotate(toAngle: 2 * CGFloat.pi, duration: 2) let playGearSound = SKAction.playSoundFileNamed("spinningGear", waitForCompletion: true) let rotateAndPlayGearSound = SKAction.group([rotateAction, playGearSound]) sun.run(rotateAndPlayGearSound, completion: { self.sunMoving = false; print("completed completion handler") }) } override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { for t in touches { self.touchDown(atPoint: t.location(in: self)) } } func touchDown(atPoint pos : CGPoint) { let touchedNodes = nodes(at: pos) for touchedNode in touchedNodes { print("touchNode: \(String(describing: touchedNode.name))") if touchedNode.name == "sun" && !sunMoving { sunMoving = true moveSun() } } }

I have the following var in an @Observable class: var displayResult: String { if let currentResult = currentResult, let decimalResult = Decimal(string: currentResult) { let result = decimalResult.formatForDisplay() UIAccessibility.post(notification: .announcement, argument: "Current result \(result)") return result } else { return "0" } } The UIAccessiblity.post gives me this warning: Reference to static property 'announcement' is not concurrency-safe because it involves shared mutable state; this is an error in Swift 6 How can I avoid this?

I'm trying to migrate my fairly large application to Swift Concurrency. I've have a class marked as @MainActor that sub-classes a 3rd party abstract class that is not migrated to Swift Concurrency. I get the following error: Main actor-isolated class 'MyClass' has different actor isolation from nonisolated superclass 'OtherAbstractClass'; this is an error in the Swift 6 language mode My class needs to be MainActor as it uses other code that is required to be on the MainActor. I can't see how to suppress this warning, I know as a guarantee that the abstract class will always be on the main thread so I need a way of telling the compiler that when I don't own the 3rd party code. import OtherAbstractModule @MainActor class MyClass: OtherAbstractClass { .... } How can I satisfy the compiler in this case?

Currently Swift Testing has much less features than XCTest, so the adoption will be very slow from our side. Notable features we miss are UI tests, performance tests and attachments. I did not want to create many issues in Swift Testing GitHub project as lots of these shortcoming are most probably tracked internally (I can see lots of references to radars in GitHub issues.) So, my question is: Is it a good idea to wait with wider adoption or should we experiment with other tools like swift Benchmarks?
