iOS how to understand symbolicated errors

Question

I'm using swift to code. I have symbolicated errors but I still can't understand exactly what the error means. I can see these informations

• The class name
• The function name

Does it contain any other information like

• Line number
• Type of error (like array out of index..)

or more?

This is another crash log which is shorter.(maybe it'll be easier to explain)

Answer 1

The first one seems like it crashes in the checkAnalytics method of your CozyConfigs class
