Playing back a buffer of float values as audio

I am new to iOS programming and am trying to manipulate some audio characteristics of an audio file which requires the audio data as float values which am able to successfully obtain.

I am stuck on how to play back that float values as audio data. I investigated a lot of iOS frameworks using its documentation but most of them do not allow me to work on float data. Its mostly reading and playing back audio files & controlling some playback parameters.

In short:

Objective: Playback a buffer/array of float values (originally audio data) as audio.

Overall Process:Audio File -> Read to float buffer (done) -> manipulate (can do) -> playback as audio (do not want to store as file)

Apologies if the question is very naive. All help is appreciated. Thanks.
