NSCocoaErrorDomain

Starting with iOS 13 I'm receiving error reports from users that cannot open their iCloud documents anymore. The error is each time: Error Domain=NSCocoaErrorDomain Code=256 The file “Untitled.txt” couldn’t be opened. UserInfo={NSURL=file:///private/var/mobile/Library/Mobile%20Documents/iCloud~com~myapp/Documents/Untitled.txt}Code 256 means: NSFileReadUnknownErrorRestarting the device solves the problem each time, but I get a lot of error reports. My app does check the availability of iCloud documents (it uses file coordination and UIDocument). This used to work fine before iOS 13.Has anybody seen a similar issue? What could be causing this and how could I collect more useful debug information to get to the bottom of this?

I'm in the process of porting over the logic from the background scripts of a Chrome/Firefox web extension to a Safari App Extension. I'm very new to Xcode, so it's taking some time learning how to interpret and confront the issues I'm encountering.I have a test project up and running, my content scripts are getting injected successfully into Safari, and I have updated the messaging logic to account for the different API's used in Safari App Extensions. Dispatching messages back and forth between Swift and Javascript is working. I was just about ready to get into migrating the Javascript logic over to Swift, but after I switched the scheme to my app extension to make use of Xcode's console, errors started appearing and Safari is now closing about 30 seconds after I run the project if I do nothing in the browser. If I click on the extension's toolbar item or setup a timer to dispatch a message to the Safari principle class, the browser will remain open for a few minutes, then eventually closes.Through a ton of

I've upgraded my macOS to Catalina. Then I tried to run via Xcode my macOS VPN app (implemented with Packet Tunnel Provider) -The VPN fails to connect and I see at the Console a lot of errors, such as:Current bundle (/Users/myClientPath/Client.app) does not have a SystemExtensions directoryNESMVPNSession[Primary Tunnel:myDetails:(null)]: Received a start command from myClient[2061]Found 0 (0 active) registrations for com.my.bundle.id.extension (com.apple.networkextension.packet-tunnel) - this msgs repeats several timesNEVPNTunnelPlugin(com.my.bundle.id[794]): Validation of the extension failedNESMVPNSession in state NESMVPNSessionStateStarting: plugin NEVPNTunnelPlugin started with PID 0 error (null)Hub connection error: Error Domain=NSCocoaErrorDomain Code=4097 connection to service on pid 0 named com.my.bundle.id.extensiondisposingFailed to start extension com.my.bundle.id.extensionNSDebugDescription=connection to service on pid 0 named com.my.bundle.id.extensionHow can I solve it?

Hi,we have app in store, that is frequenty updated and currently up to date - build with latest xCode againts latest SDK. However, there started to appear strange bug just after iOS 13.2. This bug never happens on older iOS.We are using pretty standard function to initialize persistent storage: let storeDescription = NSPersistentStoreDescription() storeDescription.url = databaseDirectory.appendingPathComponent((modelName).sqlite) let container = NSPersistentContainer(name: modelName) container.persistentStoreDescriptions = [storeDescription] container.loadPersistentStores(completionHandler: { (storeDescription, error) in if let error = error as NSError? { Check the error message to determine what the actual problem was. */ fatalError(Core Data initialization error (error), (error.userInfo)) } }) return containerThis code, that worked fine now fails to about 10% of customers - with:crash_info_entry_0 Fatal error: Core Data initialization error: Error Domain=NSCocoaErrorDomain Code=256 The file “Geotag

I need to send a mail(s) in the background for my app. What is the best way of doing this? I have tried Mailgun, but hav not got it working. Any tips on what the best/easiest way to send mail in background? Here´s the code I was trying for Mailgun: let parameters = [ from: my@mail.com, to: you@mail.com, subject: Test, text: Testing] let header : HTTPHeaders = [ Authorization: MY-KEY, Content-Type : application/x-www-form-urlencoded] let url = MY-URL AF.request(url, method: .post, parameters: parameters, encoding: URLEncoding.default, headers: header) .responseJSON { response in print(Response: (response)) }This throws the following error:failure(Alamofire.AFError.responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(error: Error Domain=NSCocoaErrorDomain Code=3840 Invalid value around character 0. UserInfo={NSDebugDescription=Invalid value around character 0.})))

I could not find any way to create an extension with permissions to read the URL without also asking for permission to read the FULL DOM including passwords.A user sent me this screen shot showing an AD BLOCKER that somehow does not read the DOM!My app needs only see the URL, we do NOT read the DOM at all and I don't want to ask for permission to read the entire DOM!The documentation CLEARLY says there is only All Some or Nonehttps://developer.apple.com/documentation/safariservices/safari_app_extensions/safari_app_extension_info_property_list_keys/adjusting_website_access_permissions?language=objcHow does an app NOT ask for permission to read passwords and crazy stuff?Thanks for what must be obvious!This is my first Safari Extensionoh, ok, I guess I can't attach a photo but you get the idea.If I ask for Allowed to be any twitter.com domain, and Some allowed I getError connecting back to host app: NSCocoaErrorDomain, code: 4099Here's my plist XML <?xml version=1.0 encoding=UTF-8?><!DOCTYPE pl

I have an app that recently started building/running under Catalina and its simple state preservation/restoration code has suddenly stopped working.The code archives an array of custom objects into an NSData blob that gets saved somewhere. Later, that data is decoded back into the array which is used to restore the state.Distilling the problem, I've created the following example:#define SECURE 1 #if !SECURE // The unsecure example UnsecureObject* bonnie = [UnsecureObject new]; bonnie.property = @Bonnie Elizabeth Parker; UnsecureObject* clyde = [UnsecureObject new]; clyde.property = @Clyde Champion Barrow; NSArray<unsecureobject*>* rootObject = @[ bonnie, clyde ]; #endif #if SECURE // Secure example SecureObject* francis = [SecureObject new]; francis.property = @Francis Crick; SecureObject* james = [SecureObject new]; james.property = @ James Watson; NSArray<secureobject*>* rootObject = @[ francis, james ]; #endif // Encode an array of objects into a data blob NSError* error = nil; NSData* data = [

I have been developing my app and testing against an iPhone 8 simulator with no problems during the develoopment phase.The app works by taking the user to their photo album when it starts where the user is able to select a photo for editing. Once the user has given access to their photo album the available photos are displayed in a grid.Today I decided to test it running on other simulators (e.g. iPhone 11 Pro). Upon starting, the user is asked to permit sccess to the photo album. Upon giving access, the app crashes. If I then start the app again it works fine.I really don't know what the problem is. The log message seem to indicate a SQLite problem. I am not using SQLite in my code directly.Here's an extract of the start of the log messages I see upon crashing:2020-01-26 12:11:34.728080+0000 BrickArt[3337:420337] [error] error: -addPersistentStoreWithType:SQLite configuration:(null) URL:file:///Users/wayne/Library/Developer/CoreSimulator/Devices/763DCD5F-2F8B-484A-869B-8A0FE88F91CC/data/Media/PhotoData/Photo
