导读：struct Person{ var name:String var age:Int var height:Double? } let aPerson = Person(name:"xijinping",age:48,height:180) let structMirror = Mirror(reflecting: aPerson).children let numChildren = structMirror.count print("child count:(numC

struct Person{
var name:String
var age:Int
var height:Double?
}

let aPerson = Person(name:"xijinping",age:48,height:180) let structMirror = Mirror(reflecting: aPerson).children let numChildren = structMirror.count print("child count:(numChildren)") for case let (key,value) in structMirror { print("name: (key) value: (value)") }
