Hi All, I work on a cross platform app, iOS/macOS. All devises on iOS could synchronize data from Coredata : I create a client, I see him an all iOS devices. But when I test on macOs (with TestFlight) the Mac app could not get any information from iOs devices. On Mac, cloud drive is working because I could download and upload documents and share it between all devices, so the account is working but with my App on MacOS, there is no synchronisation. idea????

Hi All, I have an application for iPad and iPhone, and now I would you to extend it with macOs Environnement. What is the best practice to use my iOS app on MacOs?

This error is not present in all views, just few ones...and I do only fetch for the moment, no create data in debug the fetch show duplicate values, why I do not understand this behavior because on my database before using two ipad, I had only one Record for a element not twice??? myarray = try moc.fetch(ReferencesRequest) same record present twice in the array after fetch

Today, I'm working without cloudkit (all data are in a local Coredata), with one database on my Xcode project but with 2 containers on app.delegate : one for a test environment : with storeURL ---> test.sqlite one for a production environment : with storeURL --> production.sqlite Everything is ok, the test data, is really separate from production data. Now, I try to use cloudkit functions : I change NSPersistentContainer to NSPersistentCloudKitContainer it's working and I could use data on 2 iPads. BUT if I switch the test to the prod, now the data from test environnement is duplicate on the production environnement. what mistake am I making? How could I use my two storeURL with cloudkit coredata? Thanx for your help.
