cloudkit

I'm planning to develop an App used to share infos about geographic locations (coordinates, notes, pics), a kind of Treasure Hunt and I did not understand if it is possible, using CloudKit, to share part of a private container between users. If it is, how can I do that? I'd need to create something like Apple does in the Reminders App, where a user can "invite" other users and have a common list to share between them all where everybody can insert or edit stuff. Eventually if it's not possible to do it using CloudKit, can I do that with Parse? Thank you! Data in the private container can not

I am curious is it somehow possible to increment a field value in a CKRecord variable without fetching? So on client I am not curious about the recent value, I just want to increase whatever be the value is. The reason, operation should be as quick and easy as possible, instead of two message 'stream', I want initiate only one. Unfortunately you can not. You have to read, change and then write the record. Make sure that you use the CKModifyRecordsOperation and leave the savePolicy to CKRecordSaveIfServerRecordUnchanged If you get an error then you could try read and write the record again. 来源：

I manage to save, change and delete records in Apples CloudKit. I even got notifications working with subscriptions, what I can not find out is, how do i list all subscriptions for the current user. Here is my code so far: let operation = CKFetchSubscriptionsOperation() operation.fetchSubscriptionCompletionBlock = { (d, e) -> Void in println("got subscription") if e != nil { println("Error") dump(e) } dump(d) } publicDatabase.addOperation(operation) What I got is: got subscription Error - <CKError 0x14db0ed0: "Invalid Arguments" (12)> #0 - 0 key/value pairs What are the Invalid Arguments ? And

Say I have 2 entities in my CloudKit database: - Album - (NSString) title - Photo - (NSString) name - (CKRefrence) album Photos have a CKReference to an Album. This means that 1 album can have many photos (as expected). I have a screen where I want to display all albums, and how many photos are in each album. What is the best way to query for this? If I query for Albums right now, each album knows nothing about its photos. For each of the album object anAlbum, you would form your predicate and query the Photo record type like so: let predicate = NSPredicate(format: "album == %@", anAlbum) let

I'm writing a Swift app with CloudKit. When a record is modified in CloudKit by a device, I want the corresponding records to be updated in the local storage of the other devices without displaying a push notification. Do I need to call registerUserNotificationSettings in didFinishLaunchingWithOptions (meaning that the user has to accept the notifications for my app) even if I don't plan to display any push notification? application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert, categories: nil)) Yes you do need to call registerUserNotificationSettings even all

I watched last WWDC 2016 What's New with CloudKit to understand how to share records with other users using CKShare Single record sharing: I am able to share and retrieve a single record i.e if xyz@gmail.com has created and shared a single record to abc@gmail.com Multiple records sharing: let's say there are 10 records and xyz@gmail.com wants to share to abc@gmail.com . I am facing the issue when user xyz@gmail.com shares multiple records to user abc@gmail.com What I have tried so far: First I created 3 note records: Note1 Note2 ( set parent as Note1 ) Note3 ( set parent as Note1 ) I shared

To retrieve actual logged in iCloud user's info via CloudKit, I need to call the discoverUserInfoWithUserRecordID method. Its API says: The user must have granted the CKApplicationPermissionUserDiscoverability permission for this container. How does it work? Swift CKContainer.defaultContainer().requestApplicationPermission(CKApplicationPermissions.PermissionUserDiscoverability, completionHandler: { applicationPermissionStatus, error in // check (applicationPermissionStatus == CKApplicationPermissionStatus.Granted) }) Objective-C [[CKContainer defaultContainer] requestApplicationPermission
