Reroute iPhone speaker sound to Bluetooth speaker - ios

I have to implement one iOS app i.e reroute sound from iPhone speaker to Bluetooth speaker. I have searched and got one sample link. In this sample whatever you say in the mic, that sound comes from the speaker. But my requirement is I have to reroute the speaker sound to Bluetooth speaker. Still trying to implement it. Any ideas/suggestions could be very grateful.

How can I disable bluetooth earphones from automatic playing audio as soon as they are connected?

I'm building an audio application for iOS in Swift.
Every time I connect my bluetooth earphones, it automatically starts playing music from my Music (iTunes) app. I'm on iOS 14.4.
Is it possible to disable this behavior programatically? Or this behavior is preempted from my specific bluetooth earphones?
Is it related to AVAudioSession.RouteSharingPolicy?

AVAudioSession switching speaker from receiver speaker to iPhone speaker

I am using AVAudioSession for VOIP and sometimes when the app goes to the background or the volume gets adjusted the speaker switches from the earpiece speaker to the main iPhone speakers.

IOS app - bluetooth audio enabling

I'm working on an IOS 6 app that's currently in development. The app has about 5-6 snippets of audio that play at various stages, currently when the device is paired with some bluetooth speakers (e.g. in a car) the audio does not play through the speakers.
Does anyone know what's involved with making this app work with paired bluetooth speakers? My initial assumption was that it wouldn't need anything extra done, it would just work. I had thought bluetooth paired speakers worked like as if you'd plugged in speakers directly into the device, all audio was routed through the speakers as long as they were paired.
This doesn't appear to be the case though.
I think you have to place an MPVolumeView somewhere in your interface, and enable the showsRouteButton property, then users can use that button to change the audio route to Bluetooth. You can also disable the showsVolumeSlider property if you don't need the volume slider.
