Logging in iOS using OS log

Once I started to play with my first app, I found myself printing into the console a lot, just to try to understand what was happening. This always felt wrong and until I had an "aha" moment by watching the presentation Explore logging in Swift at WWDC20. This opened my eyes so I started using OS log everywhere.

Here you have a simple snippet that I use everywhere:

//Import this libaray 
import os 
//Create a global logger object 
//Use the category to identify the struct/class/view.
let logger = Logger(subsystem: "com.maldonadotena.pathience", category: "datarepository") 
//Log at any part of the application
let filename:  String = "some file name that doesnt exist.txt"
logger.log("Couldn't find the file \(filename, privacy: .public)")

The official documentation is extensive, you can take a look here: Logging . But if you want just a copy and paste solution, here you have it, ready to use!.

Don't worry, be pathient!
