Oh I am sorry, I thought I deleted before posting.
Yes and as I mentioned, I am able to see it using your test console https://developer.kaltura.com/console/#/playlist.list but when I am running my project in xcode or test it on http://www.kaltura.com/api_v3/testme/ i get following message:-
{
"objects":[],
"totalCount":0,
"objectType":"KalturaPlaylistListResponse"
}
