I need to retrieve the URL of a resource contained in my Xcode project through a path that begins in the project's directory (aka mainBundle)
So if my specified path if ./snd/archer/acknowledge1.wav, I need to create a URL from that.
I know I can use NSURL(fileURLWithPath:)
for system directories, but I don't know how to do this directly from the bundle.
As of Swift 3, the answer is:
Bundle.main.url(forResource: "acknowledge1", withExtension: "wav", subdirectory: "snd/archer")
