Dictionaryをfilterするとき、別の配列から参照して絞り込む方法

Last updated at Posted at 2019-11-27
contents = [
	["name": "banana"
	"id": 1],
	["name": "cabbage"
	"id": 2],
	["name": "tomato"
	"id": 3],
	["name": "strawberry"
	"id": 4],

]

contentsId = [1, 3]

こんな配列があった時、contentsIdに含まれるIDのものだけ取り出したい時

filted = content.filter({  contentsId.contains($0.id) })

 [
	["name": "banana"
	"id": 1],
	["name": "cabbage"
	"id": 3],

]
