Pointer to blog posts does not contain the replies that belong to the post (Parse, Swift, iOS)

Question

I am working on a social iPhone app using Swift (with a Storyboard) and Parse where users can create posts and reply/comment on posts.

I am trying to create a relationship between a post and the comments that belong to it (ie: A one-to-many relationship where a post (parent) has one or more comments (child)).

This is the structure of the Parse data browser.

Post table:

Reply table:

When a user comments/replies on a post, the Reply table shows which post was commented on (the post's objectId from the Post table is shown in the post column of the Reply table (which is aa pointer to the Post object: post Pointer).

However, the reply column in the Post table (which is a pointer to the Reply table) does not show the replies that belong to the post. It's supposed to populate all the replies (reply objectIds) that were made for a given post but is not showing...Why? I appreciate your help!

Note: When a user types a comment in the textfield and presses "Send", a relationship is created when I set the post that this comment belongs to:

var postObject: PFObject?
...
@IBAction func sendCommentButtonPressed(sender: AnyObject) {
  var myComment = PFObject(className: "Reply")
  ...
  myComment["post"] = postObject
  ...
}

Now, I am not sure how and where to create the relationship to set the comment(s) to the post that is being commented on...
