What is the Swift equivalent of -[NSObject description]?

Question

In Objective-C, one can add a description method to their class to aid in debugging:

@implementation MyClass
- (NSString *)description
{
    ret         


        

Answer 1

The answers relating to CustomStringConvertible are the way to go. Personally, to keep the class (or struct) definition as clean as possible, I would also separate out the description code into a separate extension:

class foo {
    // Just the basic foo class stuff.
    var bar = "Humbug!"
}

extension foo: CustomStringConvertible {
    var description: String {
        return bar
    }
}

let xmas = foo()
print(xmas)  // Prints "Humbug!"
