Realm Swift use locally only, however it still tries to connect online

Question

I am following the realm swift getting started guide here and it is working fine. I have the following object:

class Dog: Object {
  dynamic var name = ""
  dynamic var age = 0
}

and in my viewcontroller I have

override func viewDidLoad() {
    super.viewDidLoad()

    print(Realm.Configuration.defaultConfiguration.fileURL!)

    let myDog = Dog()
    myDog.name = "Rex"
    myDog.age = 1

    let realm = try! Realm()

    try! realm.write {
      realm.add(myDog)
    }
}

little snitch reports that realm tries to connect to static.realm.io and api.mixpanel.com. How do I stop realm from attempting to connect to various servers if I only want to use it locally?

Please include more code, only from this context we cannot tell what might be "wrong". Are you sure you didn't set up a connection to a Realm Object Server? If you were only using a Realm schema with a local configuration, this shouldn't happen. — Dávid Pásztor, Aug 20 '17 at 17:45
@DávidPásztor I added all the code encompassing the problem. — Seb123, Aug 20 '17 at 18:05
You missed the most important part. Please show the code where you set up your Realm configuration. — Dávid Pásztor, Aug 20 '17 at 18:09
@DávidPásztor I don't set up any Realm configuration; this is it. — Seb123, Aug 20 '17 at 18:16

It's intended behavior.

Realm collects anonymous analytics when your app is run with a debugger attached, or when it runs in a simulator.

Please see our doc for more details.

It doesn't happen in a release build. To prevent this even in debug build, set environment variable named REALM_DISABLE_ANALYTICS.
