I found some very useful environment variables you can set on the application you are debugging when you need to see what symbols are being recorded by dlopen when it opens all of the libraries in your application: click on me, click on me please! So, from your Xcode project, double click your debug app: … Read more

Then, when I starting scripting Xcode with AppleScript, I’ve been getting a bunch of errors about the above listed library.

I have seen this in certain projects where exceptions are swallowed and the developer of the offending code never even knows that this happened.
