How to query by creationDate in CloudKit?

Question

I want to fetch the last X minutes of public/private entries from CloudKit.

I tried something in this effect but failed:

    let date = NSDate(timeIn

UPDATE 10/5/2020:

Found out my own question. You'll need to log in to CloudKit dashboard, go to Schema and make sure "Index Type" is set to queryable.

Here's more detailed document of what kind of NSPredicate you can use for CloudKit: https://developer.apple.com/documentation/cloudkit/ckquery#//apple_ref/doc/uid/TP40014043-CH1-SW8

Once setup, you'll be able to query by date like so:

let date = NSDate(timeInterval: -60.0 * 120, sinceDate: NSDate())
let predicate = NSPredicate(format: "creationDate > %@", date)
