Custom Swift Logger in Xcode 15

Build a lightweight logger for the events in your App

In big or small apps understanding realtime on debug what is happening is crucial. Inspecting the value of a property or reading the json response of a service is an every day task. To perform it you could use breakpoints on Xcode but it is not a fast option. You could use theprint command but things will get out of hands soon. The best solution is to create a custom logger tailored on your app.

Please note that in the past I have already written an article about it but with the release of Xcode 15 it is time to update the logic. The reason is simple: Apple finally upgraded their logging system removing all the previous verbosity and making it simple to use and read in the Console of Xcode.

As written before, I do not use theprint command mainly for two reasons:

• It is very easy to leave unwanted stuff in the Production build
• Sometimes it is very hard to understand where the print is coming from, especially if you are printing just the value of an object without any other labels.
