IOS - it is possible to record sound from the microphone of a Bluetooth headset and play it in the speaker of the device

I am trying to record audio using a bluetooth headset microphone and play back the device's speakers. I have seen several stack overflows that change, but still I don't get, is it possible or not? and if possible, how to do it? if anyone has any ideas please let me know.

It is possible. Use bluetooth option when configuring audio message category.



let audioSession = AVAudioSession.sharedInstance()
_ = try? audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord, with: .allowBluetooth)
_ = try? audioSession.setActive(true)
