iOS: Realm, check if the object is nil
<p>I have this code where I populate an array:</p>

<pre><code>func loadObjectsFromRealm() {
    private var myObjects: [MyObjects] = []
    guard let realm = try? Realm() else { return }
    myObjects = realmUtility.getAll(realm)
}
</code></pre>

<p>how can I check if the object is nil or not when I am going to use them?
For example:</p>

<pre><code>func getFirst() {
var myFirstObj = myObjects[0]    
}
</code></pre>

<p>Is there something to check if the object <code>myFirstObject</code> is real or not?</p>
