realm-swift: Carthage-related: warning: Swift error in module RealmSwift when trying to debug/print an object in the console

Expected Results

Be able to print the contents of let things = realm.objects(Thing.self) from the code sample(I know now there should be nothing in there but this is not relevant to the issue IMO).

Actual Results

I get this warning:

warning: Swift error in module RealmSwift. Debug info from this module will be unavailable in the debugger.## Steps to Reproduce

What are steps we can follow to reproduce this issue?

I just hit a breakpoint in an IBAction call. An then try po things in the console.

Code Sample

import UIKit
import RealmSwift

class Thing: Object {
    dynamic var name = "Thing"
}

class SomeThing: Thing {
    dynamic var number = 0
}

class NoThing: Thing {
    dynamic var iAmEmpty = true
}

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        let some = SomeThing()
        let no = NoThing()
        
        let realm = try! Realm()
        try! realm.write {
            realm.add(some)
            realm.add(no)
        }
    }
    
    @IBAction func tryStuff(_ sender: Any) {
        let realm = try! Realm()
        let things = realm.objects(Thing.self)
        
        for thing in things {
            print(thing.name)
        }
    }
}
