I am writing a wrapper over AVPlayer(say 'MyPlayer') and I have everything in control.I am adding observers on playerItem and MyPlayer.This is what happens:

SomeViewController.swift

    let player_ = Myplayer.player() 
    player_!.delegate = self
    player_!.setItemWithUrl(url_!)

So it creates an instance of MyPlayer and observers are registered with currentplayerItem and player_.
The problem is : When I set player_ to nil,'deinit' does not get called in 'MyPlayer.swift'.What could be the problem?

how are you checking that deinit is called or not – Nikhil Manapure Dec 04 '16 at 12:27
`MyPlayer.h`means it's an obj-c header file. deinit is for swift. – haik.ampardjian Dec 04 '16 at 12:28
deinit{print("in deinit")} – Reckoner Dec 04 '16 at 12:28

what's `player()` func is? Is it static instance? What's the delegate? is it a class type or a protocol? Is it optional? Please paste the code of `MyPayer` – haik.ampardjian Dec 04 '16 at 12:31
player()----->It is a convenience method that returns a new instance of 'MyPlayer'.'delegate' is a protocol that I am using to update currentTime of PlayerItem. – Reckoner Dec 04 '16 at 12:33
@NikhilManapure I am printing inside deinit().Still isn't called – Reckoner Dec 04 '16 at 12:37
Post code please. – shallowThought Dec 04 '16 at 13:57
@shallowThought I just noticed that a view controller(nothing on it) does not call its deinit method.I had tried this on swift 3 and Xcode 8 earlier and it was working.So I will try that once and then post further if I still can't get it right. – Reckoner Dec 04 '16 at 17:28
I don't know what's wrong but if I'm taking an empty view controller and popping it of navigationStack,deinit() doesn't get called.So I guess its not a problem with this class only.Any ideas?? – Reckoner Dec 05 '16 at 16:54
How are the observers being registered? The object may be getting retained that way. You can use Instruments to track exactly when an object is getting retained and released. – Uncommon Feb 07 '17 at 16:53
The blocks were retaining my PGPlayer...Its working fine now :-) – Reckoner Feb 08 '17 at 06:33
