Print object properties When using description to print objects in the "Swift" iOS development

You can rewrite it directly in OC. The printable protocol is required in Swift

Look at the following example

1     Overridevar description:string {2Let properties = ["Property 1","Property 2","Property 3","Property 4"]3         4         return "\ (Dictionarywithvaluesforkeys (properties))"5}
