CloudKit, Apple’s remote data storage service, provides a possibility to store app data using users’ iCloud accounts as a back-end storage service.
Here is the same demo on Objective-C.
- iOS 8.0+
- XCode 10.2
- Swift 5
- Set up Cloud/CloudKit at iOS Developer Portal.
- Insert a bundle identifier and choose a corresponding Team.
- Select Capabilities tab in the target editor, and then switch ON the iCloud.

let predicate = NSPredicate(value: true)
let query = CKQuery(recordType: recordType, predicate: predicate)
CKContainer.default().publicCloudDatabase.perform(query, inZoneWith: nil) { records, error in
}let record = CKRecord(recordType: "RecordType")
record.setValue("Some data", forKey: "key")
CKContainer.default().publicCloudDatabase.save(record) { savedRecord, error in
}let recordId = CKRecord.ID(recordName: "RecordType")
CKContainer.default().publicCloudDatabase.fetch(withRecordID: recordId) { updatedRecord, error in
if error != nil {
return
}
updatedRecord.setObject("Some data", forKey: "key")
CKContainer.default().publicCloudDatabase.save(updatedRecord) { savedRecord, error in
}
}let recordId = CKRecord.ID(recordName: recordId)
CKContainer.default().publicCloudDatabase.delete(withRecordID: recordId) { deletedRecordId, error in
