Cannot call value of non-function type 'String?'

March 12, 2024

I am new to iOS development. I am trying to convert a date value which is in string format(2024-09-22) to 22 Sep 2024.

But I am getting:

Cannot call value of non-function type ‘String?’

while doing date formatting.

I am getting this error in dateFormatter.dateFormat(from : dateString).

I have tried a below code for the formatting.

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MMM-yyyy"
dateFormatter.timeZone = TimeZone.current
dateFormatter.locale = Locale.current
let convertedDate = dateFormatter.dateFormat(from : dateString)

Could someone help me to solve this issue?

>Solution :

You first need to get Date from given String ("2024-09-22" format: "yyyy-MM-dd"). And create one more DateFormatter to convert Date to new String:

let dateString = "2024-09-22"

let dateFormatterToDate = DateFormatter()
dateFormatterToDate.dateFormat = "yyyy-MM-dd"
let date = dateFormatterToDate.date(from: dateString)

let dateFormatterFromDate = DateFormatter()
dateFormatterFromDate.dateFormat = "dd MMM yyyy"
let result = dateFormatterFromDate.string(from: date!) // 22 Sep 2024
