How to change JSON string to date format in tableview

Question

I'm displaying JSON data using a tableView and I want to convert JSON string to date format in tableView cell.

My JSON date in string format:

"createdDate": "2018-08-16 11:34:59"

I want to convert it into date format in cellForRowAt function.

struct JSONInfo: Decodable {
    let createdDate: String
}

In my cellForRowAt function:

cell.Date.text = JSONList[indexPath.row].createdDate

let createdDate = JSONlist[indexPath.row].createdDate
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
let date = dateFormatter.date(from: createdDate)
dateFormatter.dateFormat = "dd/MM/yyyy"
let IssuedDate = dateFormatter.string(from:date!)

let lastDate = JSONlist[indexPath.row].dueDate
let dateFormatters = DateFormatter()
dateFormatters.locale = Locale(identifier: "en_US_POSIX")
dateFormatters.dateFormat = "yyyy-MM-dd HH:mm:ss"
dateFormatters.timeZone = TimeZone(secondsFromGMT: 0)
let dates = dateFormatter.date(from: lastDate)
dateFormatter.dateFormat = "dd/MM/yyyy"
let DueDate = dateFormatter.string(from:dates!)

It's getting error in lastdate. I get the error here:

let DueDate = dateFormatter.string(from:dates!)

i want in dd/mm/yyyy format and json data is in string and im also using protocol in string — user9772943, Aug 20 '18 at 12:02

You could change your struct to hold a `Date` object and use a `JSONDecoder.DateDecodingStrategy` when decoding your json data, that way you would only need to format once, from Date to String, when showing the value in the cell. — Joakim Danielson, Aug 20 '18 at 12:20
The error means that `dates` is `nil`. And `dates` is `nil` because `lastDate` is not in the format `yyyy-MM-dd HH:mm:ss`. — rmaddy, Aug 20 '18 at 14:09

In which format do you want to convert. Try this one with your desired format

if let dateString = JSONList[indexPath.row].createdDate{

let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
let date = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateStr = dateFormatter.string(from:date!)

cell.Date.text = dateStr

}

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss" //This formate is input formated .
let formateDate = dateFormatter.date(from:"2018-08-16 11:34:59")! //here will be your json string
dateFormatter.dateFormat = "dd/MM/yyyy" // Output Formated
print ("Print :\(dateFormatter.string(from: formateDate))") // Print 16-08-2018

struct ChallanInfo: Decodable { let createdDate: String } – user9772943 Aug 20 '18 at 12:13
@user9772943 put your created date here in argument of this line "let formateDate = dateFormatter.date(from:"2018-08-16 11:34:59")!" – Mahesh Dangar Aug 20 '18 at 12:15
i have json date with created date and last date the code is working with created date and getting error in last date. its saying Fatal error: Unexpectedly found nil while unwrapping an Optional value – user9772943 Aug 20 '18 at 12:49
@user9772943 if it's working with created date then it should work with last date as well the only reason can be if ur data comes null or the last date format comes in diffrent format than created date – Mahesh Dangar Aug 20 '18 at 12:51
@user9772943 print your last date and let me know how it looks – Mahesh Dangar Aug 20 '18 at 12:52
i cant print because its getting error like this Fatal error: Unexpectedly found nil while unwrapping an Optional value let date = dateFormatter.date(from: dateString) dateFormatter.dateFormat = "dd/MM/yyyy" let dateStr = dateFormatter.string(from:date!) here gets error – user9772943 Aug 20 '18 at 12:54
@user9772943 check "date!" variable you must getting it nil it means your dateString coming wrong – Mahesh Dangar Aug 20 '18 at 12:55
yeah its getting nil but json im getting full format like this "2018-08-31 00:00:00" – user9772943 Aug 20 '18 at 12:57
