It is indeed a useful tutorial, thanks @beatrixwillius. I’m curious though, since your app is written in Xojo - why not just profile the app in the IDE?

Instruments can does its gathering of stats way differently than Xojo’s profiler

Effectively Xojos profiler adds instrumentation code in every method, events, getter, setter etc and collates that
This has pro’s and cons
One is that the act of profiling slows your code down and so may hide certain runtime issues because of its overhead

The profiler in Xojo is simple. Simple sometimes is good. Most of the time I want the whole information. In Instruments I can get very detailed information. Xojo is more blunt. But I’m going to expand on that.

Thanks again for article @beatrixwillius. I had never used Instruments before but I will be using it going forwards.

More to come. The next instalment will tackle test preparation.

The next part of my series of using Instruments is done:

Not as interesting as the interface. Nevertheless, test preparation is important. Next part will be actual testing.
