AVFoundation Import Warnings after XCODE 8 upgrade : <p>Obj C project; just updated to Xcode 8 and iOS/10. App seems to work fine, however, getting warnings --</p>

<p>"Missing submodule 'AVFoundation.AVSpeechSynthesis'" 
"Missing submodule 'AVFoundation.AVAudioSession'"</p>

<p>These messages appear on the #import statements for AVAudioSession &amp; AVSpeechSynthesis.</p>

<p>Does anyone know what's going on with this?</p>

<p>TIA</p>
