According to Apples Class Reference CKQuery, the operator "CONTAINS" is one of the suported operators. However, that doesn't seem to work. I have a recordtype called myRecord, and a record with filedname "name" type String. I try to fetch the record with two different predicates, one with "==" operator, and one with "CONTAINS" operator.func getRecords(){ let name = "John" let Predicate1 = NSPredicate(format: "name == %@",name) let Predicate2 = NSPredicate(format: "name CONTAINS %@",name) let sort = NSSortDescriptor(key: "Date", ascending: false) let query = CKQuery(recordType: "myRecord", predicate: Predicate1) //let query = CKQuery(recordType: "myRecord", predicate: Predicate2) query.sortDescriptors = [sort] let operation = CKQueryOperation(query: query) operation.desiredKeys = ["name", "Date"] operation.recordFetchedBlock = { (record) in print(record["name"]) operation.queryCompletionBlock = { [unowned self] (cursor, error) in dispatch_async(dispatch_get_main_queue()) { if error == nil { print ("sucess") } else { print("couldn't fetch record error:\(error?.localizedDescription)") } } } CKContainer.defaultContainer().publicCloudDatabase.addOperation(operation) }Using Predicate1, outout is: Optional(John) sucessUsing Predicate2, outout is: couldn't fetch record error:Optional("Field \'name\' has a value type of STRING and cannot be queried using filter type LIST_CONTAINS")Also using [c] to ignore casings gives a crash.How do I use the operator "CONTAINS" correctly, and how do I ignore letter casings?
