Excess memory usage swift - swift

Question

I'm building a today extension for iOS and I'm confused why this function keeps on using more and more memory.
See the code below:
func loadActivePlayer() {
kodi.getActivePlayer {
(response) in
let result = JSON(response)
let activePlayer = ActivePlayer()
if let playerid = result["result"][0]["playerid"].int {
activePlayer.playerid = playerid
}
if let type = result["result"][0]["type"].string {
activePlayer.type = type
}
if(activePlayer.isEmpty()) {
self.loadActivePlayer()
}
else {
self.enablePlaybackButtons(true)
self.activePlayer = activePlayer
self.kodi.getItem(activePlayer.playerid) {
(response) in
var result = JSON(response)
var item = Item()
if let id = result["result"]["item"]["id"].int {
item.id = id
}
if let type = result["result"]["item"]["type"].string {
item.type = type
}
if let label = result["result"]["item"]["label"].string {
item.label = label
}
if let title = result["result"]["item"]["title"].string {
item.title = title
}
if let season = result["result"]["item"]["season"].int {
item.season = season
}
if let episode = result["result"]["item"]["episode"].int {
item.episode = episode
}
if let showtitle = result["result"]["item"]["showtitle"].string {
item.showtitle = showtitle
}
dispatch_async(dispatch_get_main_queue()) {
self.itemTitleLabel.text = item.title
self.itemShowTitleLabel.text = item.showtitle
self.itemSeasonEpisodeLabel.text = "S\(item.season)E\(item.episode)"
}
self.loadActivePlayer()
}
}
}
When it goes in the if(activePlayer.isEmpty())
the memory usage increases and increases and increases, quite irritating.
But when it goes into the else, the memory usage stays almost the same, it does not increase significantly.
Can anyone help me understand why this is happening?
Thanx in advance!
