Swift string format specifier equivalent to %@

I am writing a simple app with a form in Swift, I had the app written in Objective-C to populate an e-Mail with data from text fields in a view, I used the following code to do this: 

NSString *messageBody = [NSString stringWithFormat:@"Name: %@ \nDate: %@", NameField.text, DateField.text];

I am trying to achieve the same thing in Swift, I have the following so far:

let messageBody = NSString(format: "Name: %@ \nDate: %@", NameField, DateField)

I am looking for swifts equivalent to "%@" to make the app look to the format of the string to find the data to place after "Name:".

In Swift you use \(some_printable_object_or_string)

like

let string = "Name: \(NameField) \nDate: \(DateField)"

Or you can use ObjectiveC-style formatting

let string = String(format: "Name: %@ \nDate: %@", NameField, DateField)

Don't just port Obj-c to Swift. Swift has it's own way of doing things.

let message = "Name: \(nameField) \nDate:\(dateField)"

use String Interpolation 

    let firstName = "Hai"
    let date = NSDate()
    let messageBody = NSString(format: "Name: \(firstName) \n Date: \(date)")
    NSLog(messageBody as String)
