Hi,
I need to use AVSpeechSynthesizer to read a text to my user.
User will control reading with AirPods, so I need to use MPRemoteCommandCenter.
For now, I need to prepare my audio files using AVSpeechSynthesizer.write(_:toBufferCallback:) the create a playlist and read it using AVQueuePlayer.
It works. But preparing audio files take time. I prefer to use AVSpeechSynthesizer.speak(_:) directly in background mode, and activate it via MPRemoteCommandCenter commands.
Is this possible? Or perhaps any workaround?
Thank you!

Hi,
I currently experiment migration by the code. Just for understand what happened under the hood.
It's OK for attributes. But not for relationships.
Here is my code:
let property = NSPropertyMapping()
property.name = "list"
property.valueExpression = NSExpression(format: """
FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "ItemV1ToItemV2", $source.list)
""")
item.relationshipMappings = [property]
Thank you for your help 😁
