Emile, thank you. I found the log entries thanks to your persistence!
It’s in the main log under devices. The search (like all of Apple’s search lately) is crap. You can enter your app name and all this other stuff still shows up. All search does is create a little highlighting dot next to the entry. So it gets buried under all the thousands of other messages. In the search field after searching change the “any” option to “process.” Then you will see just your app’s entries.
And while your debugging app is named DebugAppName when Xojo runs it, the process is AppName.debug in console.
