CoreBluetooth XPC Connection Invalid on dismiss viewcontroller : <p>After I have finished disconnecting from my bluetooth devices, seeing that they have disconnected in the didDisconnectPeripheral delegate, I attempt to dismiss my viewcontroller.</p>

<p>When this happens I see the message: "[CoreBlueooth] XPC Connection Invalid"</p>

<p>Is there something in specific that has to be cleaned up with Bluetooth before the viewcontroller is dismissed?</p>
