• added feature to reproduce remote items on queue only if there is WiFi connection.

• added stopPlayerAtEndOfQueue flag, to specify if the queue should be cleared upon last item on queue reproduction ended

Hi @bw0lff
Thank you for your contribution. I haven't reviewed all the code yet, but I think this could be a nice addition, although I would suggest another way.
What do you think of adding a delegate method/changing the existing func audioPlayer(_:willStartPlayingItem:) to know whether the player should start playing the item or skip it? The default implementation in case the delegate wasn't set would be true. This would obviously leave the check for "WiFi" only items to the user of the player, but that would cover any new case that should happen.

Hi @delannoyk,
The suggestions looks great for me but it should also check if is possible to play any other track on the queue (on my proposal I also changed hasNext and added a hasPrevious to do it). maybe instead of a _:willStartPlayingItem: it should have a _:isItemPlayable:, in order to have it generic delegate for both cases.

Hi @bw0lff
I noticed you updated to Swift 2.3! 👍
Do you want me to close this PR and implement the change we talked about or do you want to update this PR ?
Cheers!

HI @delannoyk,

Right now I don't have much time to work on this, therefore the best solution might be the 1st one :)

Thanks

Neither do I, so I'll leave this open until I get some time - maybe in 2 weeks on my side.

Closing this as #76 will solve this use case.
