iphone – Does the bird daemon log anywhere // troubleshooting stuck iCloud sync

Is there a way to enable iCloud Sync telemetry/logging?

Something is getting stuck uploading to iCloud but I can’t tell what it is. Popular suggestion is to kill -9 bird but that is not working for me.

1. Nothing obvious is showing up in Console.app.

2. Running bird is not helpful either:

>  ./bird -h
Usage: bird [options]

    -h,--help            show this help

3. LaunchAgent com.apple.bird.plist is not very interesting either, though it does point to the sync directory:

<key>com.apple.bird.fsevents</key>
                        <dict>
                                <key>Path</key>
                                <string>~/Library/Mobile Documents</string>
                        </dict>

How can I troubleshoot this?
