NSCocoaErrorDomain

When loading OBJs into an MDLAsset using the MDLAsset(url:) initializer (to eventually get the model into SceneKit), the operation fails frequently and inconsistently on iOS14. This operation works fine for these same files on previous iOS versions. I've also observed the bug on iPadOS, although maybe less frequently. Not sure if it's relevant, but these OBJs are pulled from server and stored locally. But this bug is occurring after files are already downloaded. I already submitted an Apple bug report FB8734401. The console output seems to indicate a failure to communicate with ModelIO XPC service. I tried restarting my device, but the bug continues to occur. Console output: connection to com.apple.ModelIO.AssetLoader was interrupted AssetLoader.loadURL errorHandler: Error Domain=NSCocoaErrorDomain Code=4097 connection to service on pid 0 named com.apple.ModelIO.AssetLoader UserInfo={NSDebugDescription=connection to service on pid 0 named com.apple.ModelIO.AssetLoader} Couldn’t communicate with a hel

I am trying to pick images from the PhotoLibrary. But When I tried to open the Photo Library by clicking the button, an empty screen appears with the following error. And this error are showed: UIImagePickerController UIViewController create error: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service on pid 0 named com.apple.mobileslideshow.photo-picker.viewservice was interrupted, but the message was sent over an additional proxy and therefore this proxy has become invalid. What do I have to do?. Please Someone Guide me through. Thankyou.

when i run my app in Xcode 12 simulator it give this error The file “ERP” couldn’t be opened because you don’t have permission to view it.

When I upgraded to Xcdoe 12 and build the previous app project, And then I got an error when running the simulator, it seemed to be a permission problem. I also went to File> Get Info for what the error said, but no exception was found. Any ideas? ======================== The following is the error content: Details The file “xxx” couldn’t be opened because you don’t have permission to view it.

Hello all! I've killed a few days trying to save a file and list it in a home directory. First I retrieve a home directory URL. I tried several options: docDir = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true) docDir = URL(fileURLWithPath: NSHomeDirectory()) In any way when running on simulator or my iPhone it results in just file:/// Well, maybe that's ok for sandboxed iOS app... After that I prepare a file URL. I tried two ways: let file = docDir.appendingPathComponent(myfile.tmp) let file = URL(fileURLWithPath: myfile.tmp) print(file.absoluteURL) Here I get file:///myfile.tmp Finally I try to create file do { try Data(count: 0).write(to: file2) } catch { print(Failed to create file: '(file)' because of: (error)) } And here is what I get On simulator: Failed to create file: './myfile.tmp -- file:///' because of: Error Domain=NSCocoaErrorDomain Code=642 You can’t save the file “myfile.tmp” because the volume “AirHD — данные” is read only.

The same code for 100 items works, but fails with exception for 600 with the Error Domain=NSCocoaErrorDomain Code=1570 title is a required value. ... all other properties of the objects are reported as nil as well. The objects are setup on the same thread and are valid before context.save is called. As I said before, it works for 100 items but fails for 600. let users = DataLayer().loadObjectsFromDB(context:self.context) var inspections = InspectionDTO.inspectionsForSave(json: json, users:users, in: self.context) do { try self.context.save() } catch { print(error._userInfo ?? ) } cross posted on stackoverflow - https://stackoverflow.com/questions/64671451/coredata-context-objects-deallocated-in-a-block/64671707?noredirect=1#comment114361636_64671707 any recommendations are greatly appreciated

import Foundation import os.log extension OSLog { private static var subsystem = Bundle.main.bundleIdentifier! static let session = OSLog(subsystem: subsystem, category: session) static func Debug(_ s: StaticString, args: CVarArg...) { os_log(s, log: OSLog.session, type: .debug, args) } static func Error(_ s: StaticString, args: CVarArg...) { os_log(s, log: OSLog.session, type: .error, args) } static func Info(_ s: StaticString, args: CVarArg...) { os_log(s, log: OSLog.session, type: .info, args) } }I defined this extension for using OSLog instead of NSLog in my project. I then wrote the following code which uses the extension:/// Instantiate an array of `Tweet`s from a property list. /// /// - Parameter url: The URL for a property list made up of one or more `Tweet`s. /// - Returns: Optinal `Tweet` array. If the property list exists, is not malformed, /// and contains all of the key/value pairs required to create one or /// more `Tweet` items, an array of said items will be returned. Othrwise, nil func tweet
