I created a new app, with today's version (Sorry where do I find the XDK version number?) using App Designer, Ionic/Angular, and console.log is not outputting anything to the debug console.
Is there a switch to enable this somewhere?
If I enable ...
app.LOG = app.LOG || true ;
...then I get logging from init-app . js but not from my app . js
Nothing special required to make console.log work. That bit you found in init-app.js is specific to that file, just a very simple redirection of console.log messages that make it easier to turn them on and off for that file. You can use whatever technique you prefer for logging.
