still happens in iOS18.0.1

as requested, I've created another feedback issue: FB15652576 on FB10392936, the error message is in the followup comments. here is the error from that issue - also an incomprehensible archive error. on that issue yes I had to lower the CloudKit operation rate to complete the upload - it took a month or 2 - it would be great if there was some mechanism for bulk uploads that bypass the throttles. But throttles shouldn't also corrupt the CloudKit database. not only would it throttle, but it would corrupt the database - the only way to recover was to reset the database and reload the schema and start from scratch- not possible in production. > [error] error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _importFinishedWithResult:importer:](1306): <PFCloudKitImporter: 0x2815fca80>: Import failed with error: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x65, 0x78, 0x61)" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x65, 0x78, 0x61)} 2022-09-08 14:04:43.136554+1000 Tupperty[1354:139717] [error] error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate recoverFromError:](2165): <NSCloudKitMirroringDelegate: 0x28397c8c0> - Attempting recovery from error: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x65, 0x78, 0x61)" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x65, 0x78, 0x61)}

no solution yet. if it happens in dev then you can reset the environment. in prod you are screwed. still happening in iOS18.3.1

I consistently get a similar incomprehensible archive error after running for a while. have a few radars open on this. so far no response: FB15652576 FB10392936 https://developer.apple.com/forums/thread/766662 https://developer.apple.com/forums/thread/713908 They broke something around the time of the iOS16 RC and it's been broken in every iOS release since. something on the CloudKit server side gets corrupted and fails. the only way to fix it is to reset the container and start again - not possible in production. Has been a show stopper for us. Had to shelve an app until its fixed.

still happening in iOS18.5

still having this problem. doesnt work with ADS turned off or on, and doesnt work logging in with password or passkey. any one have another solution?
