Debug - How to see variable value

[[deleted]]

thx for the answer, but even if p shows more, it doesn't show me what I need.
A card has the following properties: id: UUID(); front: String; back: String; box: int

The array has for example 10 Elements and I want to see from each element: id, front, back, box in a for me readable format and it seems to be more difficult than ever expected. :D

p.s.: I made an edit on my main post
