print() vs dump()

Many of us start debugging with simple print(). Let’s say we have such a class:

class Abc {
    let a = "aa"let b = “bb” }

and we have an instance of Abc as so:

let abc = Abc()

When we run the print() on the variable, the output is

App.Abc

while dump() outputs

App.Abc #0
- a: "aa"
- b: "bb"

As seen, dump() outputs the whole class hierarchy, while print() simply outputs the class name.
