Swift : inverse relationship with Parse

I have a class of users in Parse named "User".

I set a PFRelation of user with other users like this :

    let relation : PFRelation = currentUser.relationForKey("KfriendsRelation")

Lets say i have user 1, i can retrieve all users that this particular user follow with this :

   if let friendsRelation: AnyObject! = userPassed.objectForKey("KfriendsRelation")  {

    println(friendsRelation)

    if friendsRelation != nil {

   let findUser : PFQuery = friendsRelation.query()
        findUser.whereKey("objectId", notEqualTo: PFUser.currentUser().objectId)


findUser.findObjectsInBackgroundWithBlock....

What should i do if i want to retrieve all users that follow user 1 ?

I made this but it doesn't work :

  let findUser : PFQuery =  PFQuery(className: "kfriendsRelation")
         findUser.whereKey("User", equalTo: user 1)



            findUser.findObjectsInBackgroundWithBlock...
