Hello, I just opened today the MacBook run my app in my device and get this error, yesterday I didn’t get any error. Seems it’s about StoreKit, but I did not change anything. My app is currently on production and works properly. “The certificate for this server is invalid” Anyone with the same problem?

Hello, I'm building a freemium app with CoreData. One of the subscription features is to unlock "creating unlimited items". So if the user don't subscribe have a limit of i.e 10 items. I have restricted the item creation when the limit is 10 items, but when a user becomes subscriber and then cancel subscription I need to "lock" the previously created items (until 10) and leave only for delete (if the user wants). I will use a lock image over the item. I'm looking for the best way to do this. I have the FetchRequest, then filter with some parameters like "search text" or type and then show in a View. How can be a good solution of it? I'm thinking in ".firstIndex(of: )", but don't seems the optimum solution because it will called everytime the view is generated... Any ideas? Thanks!!

Hello, I'm using CloudKit for sharing CoreData objects. In my app, any time a user share an object (that previously doesn't has shared) I create a new sharing zone with the CKRecord. Also I'm using UICloudSharingController, so in this page when the user select "Stop sharing" (from the UICloudSharingController) it works, and all the items created in this Zone persist on it. I have two questions or doubts: When I delete all the items in the zone, the zone doesn't delete it self. So I have many Zones wihout items. I have to delete manually detecting what are the last item on it? If I don't want to share this (I stop sharing), exist any "easy" way to move all the items to my "default zone"? Thanks in advance, David

Hello, I'm going to implement CloudKit for my project, allowing the users share data. At this moment, I'm researching the Apple project (link below) and documentation for this purpose, and I see many times "CloudKit has a limit on how many zones a database can have." So I have doubts about what is this limit. For my purpose, each user will share 10/15 objects (imagine posts with: title, notes and photos) as maximum. This zone limit is per user? I have to worry about this limit with my expected usage of sharing / per user? The apple project: https://developer.apple.com/documentation/coredata/sharing_core_data_objects_between_icloud_users Thanks in advance, David

Hello, Im trying to use in-app purchases for first time. I have followed the tutorial for StoreKit 2 from the WWDC21 and in the simulator with the StoreKit Configuration File all was OK. But now I want test to the real server and I have this response: Error enumerating unfinished transactions for first transaction listener: Error Domain=ASDErrorDomain Code=509 "No active account" UserInfo={client-environment-type=Sandbox, storefront-country-code=USA, NSLocalizedDescription=No active account} In "Run" -> "StoreKit configuration" I have selected none In AppleStoreConnect I have created the auto-renewal suscription like in my StoreKit configuration. Also I create a new StoreKit configuration from the AppleStoreConnect and with this file its OK too. None of my testflight testers can see the options to purchase. I dont create any sandbox user. It's the problem? I saw in the documentation thats not needed. I am thankful for any kind of help. David
