Background Assets: Not work in iOS 16 developer beta 1?

I use Xcode 14 Beta to create a Background Download extension target for a simple test. But none of the extension callbacks is called after I install the debug version or ad-hoc version. I've checked the system console log for detail research but found nothing.

Is there any debug tool to trigger this mechanism or sample project I can test?

Great question! We recognize that this is a current limitation with developing a background assets extension. We're working on a solution that will help you trigger your extension entry points.

We'll update the documentation once the tool is available. [https://developer.apple.com/documentation/backgroundassets)

Accepted Answer

Xcode 14 Beta 3 has been released today, which includes support for simulating the extension on an attached iOS device.

man backgroundassets-debug

Seems like backgroundassets-debug is not working.

I use backgroundassets-debug -s --app-update --app-bundle-id *** --device-id yyy to test a new BackgroundDownloadHandler. But the console.app tells us that the extension is kill by SpringBoard.
