I write a lot of messages to System.DebugLog to help me debug code. I’m looking for a way to see the messages to find where my compiled code is bogging down. The documentation says it’s writing the message to the Console on the Mac, but I don’t know how to view the console. I’ve opened the Console app, but I can’t find the messages I’m writing.

Enter the name of your app, click start, wait some time, click on stop.
It’s easier to see the DebugLog messages if you prefix them.
To analyse speed a better method is to use profiling in Xojo or Instruments.
I’m sorry; I’m confused.
- I was running the app tonight and it was sending messages to the console. But when I select my laptop and All Messages, the main panel is empty.
- I don’t know what profiling or Instruments are. I didn’t find anything about Instruments in the documentation that looked pertinent. I found entries for Stopping and Starting profiling but it didn’t provide any explanation on what it does or how to use it.
- You need to click on the Start button. Alternatively you can use an app like BackLog ( Using BackLog to get information from the Console ) to read information from the Console.
- The documentation on the built-in profiler looks very thin. I found an older YouTube video which contains more information: https://www.youtube.com/watch?v=khFeFLSbPNA .Instruments is part of Xcode. I have an older series on Instruments on my blog ( Blog: News and Tutorials about Mail Archiver ).
Personally the way I do this is I have a method called Log that checks #if DebugBuild and then either does System.DebugLog or appends to a text file if the machine name is my dev box.
You know there’s a profiler for looking at this, right?
