This is the code I use: @MainActor func picker()->UIViewController{ let pickerController = MPMediaPickerController(mediaTypes: .music) print(pickerController) pickerController.showsCloudItems=true pickerController.prompt = NSLocalizedString("Add pieces to queue", comment:""); pickerController.allowsPickingMultipleItems=true; pickerController.delegate=MPMusicPlayerControllerSingleton.sharedController(); return pickerController } MainActor @IBAction func handleBrowserTapped(_ sender: AnyObject){ if let pickerController=contentProvider?.picker(){ self.present(pickerController, animated:true, completion:nil) } } And this his is the crash log: *** Assertion failure in -[MPMediaPickerController_Appex requestRemoteViewController], MPMediaPickerController.m:523 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'remoteViewController cannot be nil -- process will crash inserting in hierarchy.

... and I managed to fix most issues coming out, but for a specific issue in an class adopting a protocol; basically it is a support class to be used by the view controller and so I wanted to keep it in background, so I created a new actor and I wanted to use it for this protocol and adopting classes. Yet I came out with a host of errors I have no idea about how to cope with: :

When I try to validate my app I get the following error: Invalid bundle. Because your app supports Multitasking on iPad, you need to include the LaunchScreen.storyboard launch storyboard file in your com.augmentedReality.virtualTags bundle. Use UlLaunchScreen instead if the app's MinimumOSVersion is 14 or higher and you prefer to configure the launch screen without storyboards. For details, see: https:// developer.apple.com/documentation/bundleresources/information_property_list/ uilaunchstoryboardname (ID: 236f630a-a014-48e8-910a-77d9c0ff6f51) What should I do to fix it? In the previous Xcode version and on another app it did not appear. MacBook Pro M5, Tahow 26.1, Xcode 26.1.1

When I try to archive an app in order to submit it to the App Store I receive the following errors I do not know how to fix: error: Framework /Users/fbartolom/Library/Developer/Xcode/DerivedData/Virtual_Tags-apzduassdiglhcapscsllvzbfgid/Build/Intermediates.noindex/ArchiveIntermediates/Virtual Tags/InstallationBuildProductsLocation/Applications/VirtualTags.app/Frameworks/StoreKit.framework did not contain an Info.plist (in target 'VirtualTags' from project 'Virtual Tags') error: Framework /Users/fbartolom/Library/Developer/Xcode/DerivedData/Virtual_Tags-apzduassdiglhcapscsllvzbfgid/Build/Intermediates.noindex/ArchiveIntermediates/Virtual Tags/InstallationBuildProductsLocation/Applications/VirtualTags.app/Frameworks/Security.framework did not contain an Info.plist (in target 'VirtualTags' from project 'Virtual Tags') error: Framework /Users/fbartolom/Library/Developer/Xcode/DerivedData/Virtual_Tags-apzduassdiglhcapscsllvzbfgid/Build/Intermediates.noindex/ArchiveIntermediates/Virtual Tags/InstallationBuildProductsLocation/Applications/VirtualTags.app/Frameworks/CloudKit.framework did not contain an Info.plist (in target 'VirtualTags' from project 'Virtual Tags') MacBook Pro M5, Tahoe 26.1, Xcode 26.1.1

When I try to post a LocationAnnotations of a subclass respect to the one defining variable sceneLocationView, by way of: sceneLocationView.addLocationNodeWithConfirmedLocation(locationNode: bannerAnnotationLocation) When I enter in: public func addLocationNodeWithConfirmedLocation(locationNode: LocationNode) { if locationNode.location == nil || locationNode.locationConfirmed == false { return } updatePositionAndScaleOfLocationNode(locationNode: locationNode, initialSetup: true, animated: true) locationNodes.append(locationNode) print(sceneNode?.description ?? "nil") self.sceneNode?.addChildNode(locationNode) } I find sceneNode to nil, like if the effect of the renderer is lost when subclassing. I also tried to create a new variable in the subclass also assigning SceneLocationView(), but sceneNode remains nil. What to do to force it to assume a value?

I'm migrating my apps to the SceneKit platform that Apple request to adopt. Yet for an app with an iPad specific version I was not able to find the value in the ScenManifest to use to designate the iPad storyboard. May someone help? Thanks.

After two types of objects correctly inserted as nodes in an augmented reality setting, I replicated exactly the same procedure with a third kind of objects that unfortunately refuse to show up. I checked the flow and it is the same as the other objects as well the content of the LocationAnnotation, but there is surely something that escapes me. Could someone help with some ideas? This is the common code, apart of the class: func appendInAR(ghostElement: Ghost){ let ghostElementAnnotationLocation=GhostLocationAnnotationNode(ghost: ghostElement) ghostElementAnnotationLocation.scaleRelativeToDistance = true sceneLocationView.addLocationNodeWithConfirmedLocation(locationNode: ghostElementAnnotationLocation) shownGhostsAnnotations.append(ghostElementAnnotationLocation) }

I would like to modify the content of a published LocationNode upon been clicked by the user. But unfortunately: func hitTest(_ point: CGPoint, options: [SCNHitTestOption : Any]? = nil) -> [SCNHitTestResult] returns an SCNNode array from which it is impossible to retrieve the original LocationNode being inserted in order to be able to modify it. Of course the solution would be to either insert the SCNNode corresponding to the inserted LocationNode in a custom class or conversely insert the identifier of the custom object as a tag of the LocationNode, in order to solve the issue. But both options seem impossible to implement. May anyone help me?

When I execute: geoCoder.reverseGeocodeLocation(location, completionHandler:{[weak self](placemarks, error) in print("reverse geocoding location after altitude: ",location.altitude) print("placemark location first", placemarks?.first?.location?.altitude ?? -1) The input CLLocation has correct altitude 25, instead the location in the output placemarks have altitude 0, when of course they should have the same location. Moreover it is impossible to retrofit any data in the returned placemarks as they are portrayed as a read only property.

I need to elicit the location of the user in the Siri intents and so I call: override init(){ super.init() self.locationManager=CLLocationManager() self.locationManager.delegate = self; self.locationManager.startUpdatingLocation() self.locationManager.requestWhenInUseAuthorization() } Still neither public func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) nor public func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) are ever called, notwithstanding the presence of the correct entry in the info.plist, the inclusion of the library and the indication of the delegation with: class IntentHandler: INExtension, INSendMessageIntentHandling, CLLocationManagerDelegate, UISceneDelegate are ever called. Is there any problem with CLLocation manager on intents? What would be a big problem as there is no way to share information with the main app!

I have a warning on my AR app Virtual Tags that since July does not show its camera information telling: "ARCL.SceneLocationView implements focusItemsInRect: - caching for linear focus movement is limited as long as this view is on screen." I tried inserting the function, but documentation does not explain what it should return and how to generate it. Is someone able to help me? Thanks,

I have an app on the App Store for many years enabling users to post text into clouds in augmented reality. Yet last week abruptly upon installing the app on the iPhone the screen started going totally dark and a list of little comprehensible logs came up of the kind: ARSCNCompositor <0x300ad0e00>: ARSCNCompositor (0, 0) initialization failed. Matting is not set up properly. many times, then RWorldTrackingTechnique <0x106235180>: Unable to update pose [PredictorFailure] for timestamp 870.392108 ARWorldTrackingTechnique <0x106235180>: Unable to predict pose [1] for timestamp 870.392108 again several times and then: ARWorldTrackingTechnique <0x106235180>: SLAM error callback: Error Domain=Slam Error Code=7 "Non fatal error occurred due to significant drop in a IMU data" UserInfo={NSDescription=Non fatal error occurred due to significant drop in a IMU data, NSLocalizedFailureReason=SlamEngineNodeGroup Failure: IMU issue: gyro data stream verification failed [Significant data drop]. Failed on timestamp: 870.413247, Last known timestamp: 865.350198, Delta: 5.063049, System timestamp: 870.415781, Delta between system and frame: 0.002534. } and then again the pose issues several times. I hoped the new beta version would have solved the issue, but it was not the case. Unfortunately I do not know if that depends on the beta version or some other issue, given the app may be not installed on the Mac simulator.

I am trying to extract a protocol from an app to be able to use it in a siri intent. Yet when I compile it I get: note: Injecting stub binary into codeless framework (in target 'Virtual Tags Framework' from project 'Virtual Tags Framework') /Users/fabriziobartolomucci/Library/Developer/Xcode/DerivedData/Virtual_Tags_Framework-chxutmulwgujeiceazyyzaphwner/Build/Products/Debug-iphonesimulator/Virtual_Tags_Framework.framework/Frameworks/ARKit.framework/Versions/A: bundle format unrecognized, invalid, or unsuitable Command CodeSign failed with a nonzero exit code

I‘m using a UITextView to allow users to post messages in AR in my app virtual tags - you may check by yourself, it is free - but it just allows to append text at end with no possibility of moving the cursor or do everything else. I opened a new project adding a UITextView and everything worked fine. What could it be, and how to know more? thanks, Fabrizio
