On XCode 6, everything works well on device, but on simulator, sound is not played.
There is my swift code :
var url = NSURL(string: \"http://my.ur
I was having this problem, the comment from @Matti Jokipii, helped me a lot.
You need to have a sound input enabled, so your Mac doesn't give you the null exception.
Go To System Preferences > Sound. And Check you have some input connected. If not, you will have to add a microfone, and re-rerun the app.
