I got this message "Account temporarily unavailable due to bad or missing auth token" when I try to save to privateDatabase in CloudKit, using the CKDatabase.save(record:completionHandler). It looks like the error that was posted about here on stackoverflow has reappeared. The fix for that other problem was a bug in Apple's side. Anyone have this problem recently and have a solution?

I've never had this error before. When I try to run an iOS project in Xcode with a simulator, I get this message from XCode: "Unable to lookup in current state: Shutdown", and a button that says "Details", and a button that says"OK". When I quit simulator and try to run my project again, the same thing happens. When I click details it says "iPhone10,4 for device_model. The simulator is an iPhone 8 simulator. Here is what the whole thing says: (I don't know why some of the text has such a large font and is in bold.)

I'm having trouble converting a CNGroup object to a Data object and back to a CNGroup object. I decided to start rethinking the problem again. Somewhere along the way I decided that I should use the Data class to save a CNGroup object to CloudKit. I also learned that the field type to use in my CKRecord object would be of the type bytes. Am I correct so far? I am able to convert a CNGroup object to a Data object and back again unless I store the Data object in CloudKit and then retrieve it before I convert the Data object back to a CNGroup object, in which case I get an error when I try to access the pointee property of the typed pointer. That would be an UnsafeBufferPointer, an UnsafeMutableBufferPointer, or an UnsafePointer. I've tried a lot of different code using different ways. It is impractical to put so much code in my post. I have used the copyBytes method and the withUnsafeBytes method of the Data object. There is one simple code, and that is when I converted the CNGroup object to a Data object: func convertCNGroupToData(fromCNGroup group: inout CNGroup) -> Data { return Data(bytes: &group, count: MemoryLayout.size(ofValue: group)) } I am looking for a simple way to do what I want. I am relooking at Apple's documentation of Data and NSData. I am not able to be more specific with this question. I appreciate any effort to help me with this.

When I try to delete records in CloudKit Dashboard by querying them and then selecting them and clicking on the trash can icon at the top right-hand side of the query results, I get a message box saying that those records will be deleted in a box shaded red, but the delete button at the bottom right-hand side of the box is grayed out and doesn't respond when I click it. These records were root records of shares whose shares in the cloudkit.share table I have deleted using CKModifyRecordsOperation. For some reason when I deleted the shares, the root records were not deleted. Then when I try to delete those root records using CKModifyRecordsOperation, I got an error. Here is my code in CKModifyRecordsOperation.modifyRecordsCompletionBlock that caught the error: if let error = error {     print("error:")     print(error.localizedDescription)     if let ckError = self.handleCloudKitError(error, operation: .modifyRecords) {         if let serverVersion = ckError.serverRecord {             serverRecord = serverVersion             print("serverRecord:")             print(serverRecord!)         }     } } Here is what my code above printed in the Debug window: error: Internal server error ModifyRecords operation error: <CKError 0x600001bb9920: "Server Rejected Request" (15/2000); server message = "Internal server error"; op = 49A32A559E4F4C11; uuid = 22F46530-5F45-463E-A21F-279C3876C897; container ID = "iCloud.us.gnolaum.Courier">

When I query for all the records of a certain record type, and then I click on the record name to view the record, I get this error at the bottom of the window pane that shows the details of the specific record: BadRequestException: endpoint not applicable in the database type 'sharedb' What is "endpoint" referring, what does it mean and what is causing this error message? Here is the part of the schema that defines the two record types involved: RECORD TYPE Group ( "___createTime" TIMESTAMP, "___createdBy" REFERENCE, "___etag" STRING, "___modTime" TIMESTAMP, "___modifiedBy" REFERENCE, "___recordID" REFERENCE QUERYABLE, debugTag STRING QUERYABLE SEARCHABLE SORTABLE, groupData BYTES, GRANT WRITE TO "_creator", GRANT CREATE TO "_icloud", GRANT READ TO "_world" ); RECORD TYPE LocalGroupIdentifier ( "___createTime" TIMESTAMP, "___createdBy" REFERENCE, "___etag" STRING, "___modTime" TIMESTAMP, "___modifiedBy" REFERENCE, "___recordID" REFERENCE QUERYABLE, groupReference REFERENCE, localGroupIdentifier STRING QUERYABLE SEARCHABLE, GRANT WRITE TO "_creator", GRANT CREATE TO "_icloud", GRANT READ TO "_world" ); The error comes when I view the details of a record of type Group. I use UICloudSharingController and CKModifyRecordsOperation as Apple Documentation shows in the Apple Documentation for UICloudSharingController and Sample Code: Sharing CloudKit Data with Other iCloud Users. It works just fine when I create the CKShare object. When I use the url to accept the share, it works fine except for the error in question, which shows when I view the record of type Group and the record of type LocalGroupIdentifier, which has a reference to the record of type Group. I use exactly one record of type Group and one record of type LocalGroupIdentifier. I used two different simulators with different Apple IDs for sharing and for accepting the share. They are both iPhone 8 with iOS 15.4. The share I create is in the private database, and the share accepted is in the shared database.

Before I update my macOS to 12.3.1, form 12.3, I want to know if anyone has installed it and if it interfered with Xcode. I heard that macOS updates faster than Xcode so that at times the new macOS requires a new Xcode that hasn't been released yet. I checked Mac App Store, and there isn't a version released after Xcode 13.3 (13E113).

I am able to share a record in CloudKit using the instructions in the Apple Documentation, including the CloudKitShare sample, but when another user accepts the share, only the root record is saved in the sharedDatabase. There is supposed to be another record that has a reference to the root record. I'm not sure what code to include in this post. Perhaps someone can tell me that much or know of a common programmer mistake that causes this error. Here is the basic code, after I have removed code not essential to the problem, to make my code easier to read. @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate {     func application(_ application: UIApplication, userDidAcceptCloudKitShareWith cloudKitShareMetadata: CKShare.Metadata) {         let container = CKContainer(identifier: cloudKitShareMetadata.containerIdentifier)         let acceptSharesOperation = CKAcceptSharesOperation(shareMetadatas: [cloudKitShareMetadata])         container.add(acceptSharesOperation)     } }

At what point in the iOS development process using Xcode is my app name reserved on App Store? Last I remember when I published my iOS app for sale status on iOS App Store at App Store Connect I had to change my published app name because there were already other apps using that name. I think that was the name that was actually showing on the App Store, and not the name I put in the Product Name field when I first create the project in Xcode. I just tried to validate my iOS app and it wouldn't validate because it said there was already an app with that "App Name". I take it that means the name I put in the Product Name field when I first created the project, if I don't change it later. Is that correct? So if my iOS app project validates, does that mean I have that App Name reserved so that no one else can use it? How do I reserve a name for my iOS app so that no one else will get it once I reserve it?

I'm trying to figure out what @MainActor means in this definition of UICloudSharingController in Apple Documents found here. Here's what it says: @MainActor class UICloudSharingController : UIViewController I couldn't find much information on Google. This Apple Documentation is the closest thing I found. Is this what i need? Here is the declaration to the MainActor class: @globalActor final actor MainActor

When I go to devices and simulators with my iPhone 8 plugged into my Mac, and then open device logs, I don't seen any recent logs. The last one was from november last year. Why are there no more recent logs? I went to my iOS device and searched for "log" in Settings, but there doesn't seem to be any setting to turn on logging. I also can't find any settings when I search for "developer" in settings. I thought I saw something in iOS that enabled me to send reports to Apple automatically on my iOS device. I don't know if that's what I really want.

I'm getting message "This operation can fail if the version of the OS on the device is incompatible with the installed version of Xcode. You may also need to restart your mac and device in order to correctly detect compatibility." when I try to run an Xcode iOS project on my iPhone 8. I'm using Xcode 13.2.1 and iOS 15.4 on my iPhone 8. This post in this forums gives the solution to restart the iOS device and I did that and also restarted the mac. My Mac has macOS Monterey 12.3. My Xcode, Mac, and iPhone 8 all have the most recent updates. That post gives an answer for the same problem but with iOS 15.2. I have recently changed settings in my iPhone 8 in Accessibility. Could that affect anything?

How do I get the answer id of an answer in a thread? I would like to know how to create a link to a specific answer of a post so I can refer to a specific answer rather than to the top of the page of the post. I noticed one link went to this address - https://developer.apple.com/forums/thread/67535?answerId=195112022#195112022. That's where I learned about the "answerId" item.

I think I'm only entertaining wishful thinking, but I hope it is possible to somehow cause my iOS app or a background task to start up when the iOS device starts up, like when it was turned off and then turned back on. Does even the user of the device have a way to do this in iOS? I saw some threads saying something like this might be possible using MDM or supervised devices or kiosk mode or guided access. Those all seem to require the user or administrators to do some setting up. I want my app or background task to be able to do what I mentioned right as it comes after it is installed from App Store.

I'm starting to look into MDM and device management for my iOS app. I'm also wondering if there is any way to allow someone on a macOS or another iOS device take control of another person's iOS device to show them how to use their device and perhaps even take control of their device while the person using the controlled device watches what the the person in control of the device is doing so he can follow along. Is there something like this that Apple already has? Is it possible to do this? If it is possible to do this, can it be done in a commonly distributed device that anyone can install from App Store and not require any additional maintenance or extra setup? I think the word I'm thinking of is "supervised". I saw that word in another post. Is it possible for one device to give control over to another user on a different device without the first device being "supervised".

I'm having trouble finding explanations for the different cases of Data.Deallocator enumeration. It's used with the [init(bytesNoCopy:count:deallocator:) initializer to Data class] (https://developer.apple.com/documentation/foundation/data/1780455-init) Here's the different cases: Data.Deallocator. The cases are: custom free none unmap virtualMemory Anyone know a website that explains those cases briefly and simply? Or do you know what they mean off the top of your head?
