Is there a way to Track/trace and log all the methods, by Class and Method name, during a debug session?

Dave Dribin covers precisely this in his article Tracing Objective-C messages.

The part you are after is probably this:

If you set the NSObjCMessageLoggingEnabled environment variable to YES, the Objective-C runtime will log all dispatched Objective-C messages to a file named /tmp/msgSends-<pid>.

Xtrace (https://github.com/johnno1962/Xtrace) has many features and works well for tracing Objective-C. One needs source access to their project, like you appear to have, and can emit messages on entry/exit, like you appear to want.

• Debug-time configuration - can hard-code or configure tracing while debugging
• Uncomplicated integration - one .mm and one .h
• NSRegularExpression matching - classes, methods, types
