Apple

I like Kyle's answer for stepping through your options in increasing order of difficulty.

The most direct analogue to the RemoteIO unit on the Mac is the AUHAL. It's a little harder to use on Mac because while iOS can only ever have one audio device, Mac can have many, so you can either get the default output unit (which is whatever is selected in System Preferences), if you want to use a specific device, you need to do a little extra work inspect hardware, get that device, and then get AUHAL from that.

Depends on what specifically you want to do. Do you already have the samples in buffers? If so, is that because you assumed you needed to do that in order to play sound?

NSSound will take care of the entire process of loading and playing an audio file.

AVFoundation operates at a similar conceptual level but gives you richer control if you want it.

If you have audio in buffers because the nature of your app requires that, Audio Queue Services is the easiest way to put those buffers out to the hardware. AudioFile will help you get the data from a file into buffers in the first place.

If you want to perform effects, Audio Units are the way to go. Audio Graphs make working with Audio Units easier and more powerful.
