Для записи воспроизведения аудиофайлов в iOS вы можете использовать платформу AVFoundation. Используйте ниже быстрый код для записи и воспроизведения аудио.
Помните, что рекордер будет записывать звук с использованием микрофона, поэтому, пожалуйста, проверьте этот код на устройстве.

Я тестировал этот код на xCode 7.0 и iOS 9.
