Fetching Multiple Records by Record Name

I have an array of record names (or strings) . I want to fetch any record in the public database which has any of these record names. How might I do this?

Solution

  • You should apply something like this...

    let filter: [String] = [ "String1", "String2", "String3" ]

let predicate: NSPredicate = NSPredicate(format: "%k IN %@", "record_name", filter)
let query: CKQuery = CKQuery(recordType: "RecordType", predicate: predicate)

CKContainer.default.publicCloudDatabase.perform(query, inZoneWith: nil, completionHandler: { @escaping ([CKRecord]?, Error?) -> Void in 
    // Do what you want with your filtered CKRecords ;)
})

    The NSPredicate uses the aggregated operator IN in order to filter by the contents of an array. More info at Predicate Programming Guide
