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

As described here, you can also use Swift's reflection capabilities to make your classes generate their own description by using this extension:

extension CustomStringConvertible {
    var description : String {
        var description: String = "\(type(of: self)){ "
        let selfMirror = Mirror(reflecting: self)
        for child in selfMirror.children {
            if let propertyName = child.label {
                description += "\(propertyName): \(child.value), "
            }
        }
        description = String(description.dropLast(2))
        description += " }"
        return description
    }
}
