How to convert Date to String in Swift [duplicate]

Question

I'm trying to call a function one argument is current time and Date and other is a file name, They both are strings. How can I convert Date() to a string. I tried:

writeToFile(content: Date(), fileName: "jm.txt") 

but it gave me error:

Cannot convert value of type 'Date' to expected argument type 'String'

Answer 1

Something like this:

let df = DateFormatter() df.dateFormat = "yyyy-MM-dd hh:mm:ss" let now = df.string(from: Date()) writeToFile(content: now, fileName: "jm.txt") 

Answer 2

You need to use DateFormatter, as stated in the docs:

Instances of DateFormatter create string representations of NSDate objects, and convert textual representations of dates and times into NSDate objects.

In your case, that would look something like this:

let formatter = DateFormatter()  formatter.dateFormat = "yyyy-MM-dd"  writeToFile(content: formatter.string(from: Date()), fileName: "jm.txt")
