Swift - Delete value from model in realm

Question

I'm trying to delete an object from my realm with swift3. When the user logs in with google, the userinfos are stored in realm db. Now I want to delete the user, when I click a button.

Here is my unfinished code:

@IBAction func deleteUser(_ sender: Any) {

    let realm = try! Realm()
    let userObject = realm.objects(userInfos.self).filter("id == 0").first
    realm.delete(userObject)
    try! realm.write

    print("deleted")
    print(userObject)
}

The code above is not working. What is wrong?

Thanks for your help !

Try:

let realm = try! Realm()
if let userObject = realm.objects(userInfos.self).filter("id == 0").first {
    print("User is existed, it's being deleted.")
    try! realm.write {
         realm.delete(userObject)
    }
    print("Deleted.")
}
else{
    print("User is not found.")
}
