Simulator device kills my bandwidth
Mac mini late 2012, Catalina 10.15.7, Xcode 12.4 When opening a device (ANY device) in Simulator, my internet usage goes up to maximum usage. Close the device and all goes back to normal. I am not running any app on the device, nor have I loaded any of my apps on the device - it's a 'clean', 'out of the box' standard device. I've gone through the whole Simulator menu structure to see whether I have missed some setting, but found nothing. This behaviour makes it near to impossible to test my app. Anything I can do to resolve this issue or do I wait for 12.5 to come out and hope it resolves itself?

Xcode NSMetaDataQuery error on device running IOS 17.5 - [ERROR] couldn't fetch remote operation IDs
Xcode 15.4 running on various IOS simulators and hardware devices from IOS 14.5 to 17.5. Part of my code presents a backup/restore page to the user which uses NSMetaDataQuery to update the GUI for files being uploaded or downloaded in iCloud. On every device I run the code everything works as expected EXCEPT one which is an iPhone 11 running IOS 17.5 (as of yesterday 17.5.1); there I get the following error once I start the query: [ERROR] couldn't fetch remote operation IDs: NSError: Cocoa 257 "The file couldn’t be opened because you don’t have permission to view it." "Error returned from daemon: Error Domain=com.apple.accounts Code=7 "(null)"" Due to this error I am getting no query updates and thus unable to display whether the file needs to upload, download or is synchronised. I am not initiating any upload or download of the backup file since it is placed in the ubiquitous container and I leave the up/download of the file over to IOS; all I do with the query is monitor the status of the file and take appropriate action to show the user the percentage of up/downloaded file. As said before it is only the one device causing me headaches so I don't know whether it has anything to do with IOS 17.5 that Apple have made changes that I am unaware of. I have access to an iPhone and an iPad running some version of IOS 16 and it's performing flawlessly. I have no other IOS17+ device to test on. The code runs very well on any 17.5 simulator, but we all know there are always some differences running code on a Device vs Simulator. Running 'startAccessingSecurityScopedResource()' which has been suggested by some returns 'true' on the simulator and 'false' on a device, but even then all devices work except one; so that does not seem to be the solution. Changing the query predicate has not helped either. How do I drill down to find the culprit - I'm at my wits' end. My very simple query initializer, startup & observers: (Please note, the code shown here is what's left after commenting out everything else. This was done to show that the problem really DOES lie with the Query) query = NSMetadataQuery.init() query.operationQueue = .main query.searchScopes = [NSMetadataQueryUbiquitousDocumentsScope] query.predicate = NSPredicate(format: "%K LIKE %@", NSMetadataItemFSNameKey, fileUrl.lastPathComponent) query.operationQueue?.addOperation({ [weak self] in self?.query.start() self?.query.enableUpdates() }) } func addNotificationObservers() { NotificationCenter.default.addObserver( self, selector: #selector(queryDidStart(_:)), name: .NSMetadataQueryDidStartGathering, object: query) NotificationCenter.default.addObserver( self, selector: #selector(queryGathering(_:)), name: .NSMetadataQueryGatheringProgress, object: query) NotificationCenter.default.addObserver( self, selector: #selector(queryDidUpdate(_:)), name: .NSMetadataQueryDidUpdate, object: query) NotificationCenter.default.addObserver( self, selector: #selector(queryDidFinishGathering(_:)), name: .NSMetadataQueryDidFinishGathering, object: query) }
