Actually the above will wipe all of your records because it doesn't select the winning objectID out of the collection of multiple results. Any good database design begins with data normalization, unique keys etc ...: Take a look at the following code by apple on how to dedupe core data records: https://developer.apple.com/documentation/coredata/synchronizing_a_local_store_to_the_cloud see CoreDataStack class

Just make sure the command line tools version matches the Xcode version installed. Best to download Xcode 13.2.1 and the matching version of command-line tools.

Stop building the benchmark project and focus on creating something.

You need to associate the test & prod with its own container id. Add them via Xcode iCloud capabilities containers list. let testContainerID = NSPersistentCloudKitContainerOptions(containerIdentifier:"your_bundle_id.test") let prodContainerID = NSPersistentCloudKitContainerOptions(containerIdentifier:"your_bundle_id.prod") Assign each container ID to the respective data store

This is most likely failing because you're ignoring failures on a non ssl http endpoint: read here if let response = try? JSONDecoder().decode([Account].self, from: data) {    DispatchQueue.main.async {              self.accounts = response     } } else { // add logic to handle api errors here }

This only tells half or less of the story. What is the button nested in? More code is needed to see what is actually causing the problem.

Button(action: {}) {                 ZStack {                     RoundedRectangle(cornerRadius: 16)                         .fill(.gray)                     Image(systemName: "applelogo")                         .resizable()                         .padding(2.0)                 }             }             .frame(width: 120.0, height: 120.0)

Who wrote the webserver? What compiler tools did you use to write the webserver? Who is sending the packets to the clients? Is your handcrafted webserver following all of the RFC-based specs? Was the webserver written with Xcode, does it run on the mac or any Apple mobile products? In this scenario, your web server is sending data in response to a client, not the other way around other than a get URL request.

Deprecated doesn't mean removed. Just means you're to prepare to stop using it before it is actually removed.

This is a Microsoft product, please ask the guys over at Microsoft.

That is a question for the guys a Microsoft.

@DelawareMathGuy this is what I had to do to trigger the FRCDelegate but this goes against the FRC automatically doing it after the performFetch fetchedResultsController?                 .publisher(for: \.fetchedObjects)                 .receive(on: OperationQueue.main)                 .sink(receiveValue: { [weak self] data in                     guard let self = self,                             let data = data else { return }                     for (index, object) in data.enumerated() {                         let indexpath = IndexPath(item: index, section: 0)                         if let controller = self.fetchedResultsController as? NSFetchedResultsController<NSFetchRequestResult> {                             self.controller(controller, didChange: object,                                             at: nil,                                             for: .insert,                                             newIndexPath: indexpath)                         }                     }                 }).store(in: &cancellables)

You have the option of a custom framework or custom library based on pods, swift package manager, etc but placing a custom UI control into the Xcode IDE is not supported hence why there is no documentation.

After watching Demystifying SwiftUI it demystified this issue.
