Using YTPlayerView to play embedded YouTube video in iOS failed with restriction error

By setting the origin property in my playerVars I was able to play the embedded video.

let playerVars = [
                     "playsinline" : 1,
                     "showinfo" : 0,
                     "rel" : 0,
                     "modestbranding" : 1,
                     "controls" : 1,
                     "origin" : "https://www.example.com"
                 ]

Then call loadWithVideoId:: as you normally would.

NSDictionary *playerVars = @{
                             @"origin" : @"http://www.youtube.com",
                             };
[self.playerView loadWithVideoId:@"videoId" playerVars:playerVars];`

This Objective-C version works for me.
