I have a date that is a string that looks like this:
Apr 25 2018 12:00AM
What I am trying to do is convert this date format to yyyy-MM-dd and then convert it back to a string, I have a tried the following:
let formatter = DateFormatter()
formatter.dateFormat = "M dd yyyy h:mm A"
let SLAIssuedFinalGradingDate = formatter.date(from: tableDic["SLAIssuedFinalGradingDate"] as! String)
formatter.dateFormat = "yyyy-MM-dd"
let SLAIssuedFinalGradingDateString = formatter.string(from: SLAIssuedFinalGradingDate!)
But SLAIssuedFinalGradingDate
always returns nil, what am I doing wrong?
Your dateFormat
for Apr 25 2018 12:00AM
is not right. You are using M dd yyyy h:mm A
, but format would be MMM dd yyyy hh:mma
.
Use this link to check date format.
Code Should be:
let formatter = DateFormatter()
formatter.locale = Locale(identifier: "en_US_POSIX")
formatter.dateFormat = "MMM dd yyyy hh:mma"
let SLAIssuedFinalGradingDate = formatter.date(from: tableDic["SLAIssuedFinalGradingDate"] as! String)
formatter.dateFormat = "yyyy-MM-dd"
let SLAIssuedFinalGradingDateString = formatter.string(from: SLAIssuedFinalGradingDate!)
