After digging a lot i found a solution. Default AVFoundation Allow to use either Microphone or Speaker at a time and ReplayKit is incompatible with AVPlayer content. So if we want to use both of them at a time we need to set AVAudioSession's Category to AVAudioSessionCategoryMultiRoute. 

do {
    try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryMultiRoute)
} catch let error as NSError {
    print(error)
}

do {
    try AVAudioSession.sharedInstance().setActive(true)
} catch let error as NSError {
    print(error)
}

I think it is a system limitation As in apple official documents it is written

ReplayKit is incompatible with AVPlayer content.
