Create Array of Dates from JSON

Question

I would like to create an array of dates (or of tuples including an index and a data) from the following JSON.

My code is creating an array but instead of creating an array of dates, it breaks up the dates into characters. What do I need to do to create an array just of dates.

JSON looks like:

let json = """
    [{"date":"2017-01-05",
     "price":119.34},{"date":"2017-01-06",
     "price":118.93}];

Code is:

let myprices = try JSONDecoder().decode([Prices].self, from: Data(json.utf8))
let dates = myprices.sorted{$0.date < $1.date}.enumerated().map {Array($0.element.date)}

Code prints to console as:

dates [["2", "0", "1", "7", "-", "0", "1", "-", "0", "5"], ["2", "0", "1", "7", "-", "0", "1", "-", "0", "6"], ["2", "0", "1", "7", "-", "0", "1", "-", "0"]]

Thanks in advance for any suggestions.

Answer 1

Replace

let dates = myprices.sorted{$0.date < $1.date}.enumerated().map {Array($0.element.date)}

with

let dates = myprices.sorted{$0.date < $1.date}.map { $0.date }

Currently you may be making let data:String change it to let date:Date and supply a formatter to the decoder check This
