Is it possible to save multiple CKRecord objects in one CloudKit operation using Swift? I know how to retrieve multiple records at once, using things like CKFetchRecordsOperation or even just a regular performQuery. I just realized that I am not sure of a way to save multiple new records in one operation. The way I have been doing that so far, seems inefficient to me. For example:
let recordsToSave:[CKRecord]!
for newRecord in recordsToSave {
if let database = self.publicDatabase {
database.saveRecord(newRecord, completionHandler: { (record:CKRecord?, error:NSError?) in
// Check if there was an error
if error != nil {
// There was an error, handle it properly.
}
else {
// There wasn't an error
if let savedRecord = record {
// Handle saved record accordingly.
}
}
})
}
And while that does work all fine and dandy, it seems to me as though it's extremely inefficient. I would think it would make more sense to have a specific function to call to save the entire array of CKRecords, instead of having to make a database call every time through the loop. Essentially here is what I'm hoping I can do:
let recordsToSave:[CKRecord]!
if let database = self.publicDatabase {
// SOMETHING HERE LIKE database.saveRECORDS (plural) ????
database.saveRecords(recordsToSave, completionHandler: { (records:[CKRecord]?, error:NSError?) in
// Check if there was an error
if error != nil {
// There was an error, handle it properly.
}
else {
// There wasn't an error
if let savedRecords = records {
}
}
})
}
As best as I can tell, and based on the information I've obtained. There isn't an actual function like database.saveRecords (plural). Unless I am missing something? I'm thinking that its not so cut and dry and that the naming is different, but I would assume there has to be something similar to that.
It seems so horribly inefficient to have to make a database call every time I go through the loop.
Does anybody know of a method to execute a save for multiple CKRecords at one time, using CloudKit? Any help at all would be greatly appreciated. Thank you in advance!
Using saveRecord in a loop is terribly inefficient. It's actually best to avoid all of the convenience methods on CKDatabase and use the appropriate operation.
To add/modify/delete one or more records, use CKModifyRecordsOperation. You can add/modify as well as deleted any number of records with a single operation. This will be vastly more efficient than using saveRecord.
I suggest you browse through the CloudKit Framework Reference to see the complete list of operations available.
