New OutputDeviceUID is nil msg when instantiating MPVolumeView

Question

Today, likely as a result of upgrading to iOS 12.3 on my test phone, I am now receiving the following notifications in my debug console when I first instantiate my MPVolumeView.

019-05-21 11:00:22.874353-0600 sports-audio-dj[3831:982163] [MediaRemote] OutputDeviceUID is nil Speaker: (null)

I receive about 10+ of these.

Here is the code that kicks it off:

let volumeView = MPVolumeView(frame: self.view.bounds)

My code hasn't changed and I'd not seen this before today and wondering if anyone knows what is bringing this about and if I need to do anything about it if something is now unhappy. My app seems to work fine despite these new notifications.

Answer 1

Apple responded today with the following:

You can safely ignore this debugging message. It will be removed in a future version of iOS.

Answer 2

iOS 13 has finally removed these errant debug messages.
