Default description property getter for types that conform to CustomStringConvertible

#Guide: DefaultStringConvertible.swift

How to use it:
1. Add the file to the project
2. Append CustomStringConvertible or CustomDebugStringConvertible protocol to the type you want to have description
3. Now you can call object.description on any custom Class or Struct you've made

DefaultStringConvertible.swift

import Foundation

extension CustomStringConvertible {
    var description: String {
            let mirror = Mirror(reflecting: self)
            var output = ""
            
            output.appendContentsOf("\(mirror.subjectType) (\n")
            for case let (label?, value) in mirror.children {
                output.appendContentsOf("    \(label) = \(value)\n")
            }
            output.appendContentsOf(")\n")

            return output
    }
}

extension CustomDebugStringConvertible {
    var debugDescription: String {
            let mirror = Mirror(reflecting: self)
            var output = ""
            
            output.appendContentsOf("\(mirror.subjectType) (\n")
            for case let (label?, value) in mirror.children {
                output.appendContentsOf("    \(label) = \(value)\n")
            }
            output.appendContentsOf(")\n")
            
            return output
    }
}
