I found two ways to do this.

  1. Generate a sysdiagnose and AirDrop it to your computer. The sysdiagnose tarball contains a bundle called system_logs.logarchive which can be opened with Console.

  • On the device, press both volume buttons and the lock button simultaneously. Release after 1 second. You should feel the device vibrate. Note that holding down the buttons for longer than that will bring up the emergency call screen.

  • On the device, go to Settings -> Privacy -> Analytics -> Analytics Data.

  • Scroll down until you see sysdiagnose_<current date>. Select it, and tap the send button. Tap on your computer name to send the log via AirDrop.

  • On your computer, accept the AirDropped item. This will be a tar.gz file

  • Open the tar.gz file and decompress. Inside, you will see system_logs.logarchive

  • Double-click system_logs.logarchive. This should open the bundle in Console.

  1. When the device is connected to your Mac over USB, you can gather logs from it using the log tool. From Terminal, run log collect --device --output logs.logarchive. Then, open logs.logarchive in Console.

Note that Console will only show the last 5 minutes of messages by default. You can change this near the bottom of the window:

The "Showing" drop-down list
