Parse a local Json file and display it in table view (Swift4.2)

This is a sample code that parses the locally added JSON file and displays it in TableView.
It would be better to use SwiftyJson or something like that, but this time I wrote it without using it.

	{
	"data": [{
	"id": 0,
	"name": "Apple"
	},
	{
	"id": 1,
	"name": "Water melon"
	},
	{
	"id": 2,
	"name": "Peach"
	},
	{
	"id": 3,
	"name": "Cherry"
	},
	{
	"id": 4,
	"name": "Grapes"
	},
	{
	"id": 5,
	"name": "Pear"
	}
	]
	}
